Chapter 1: Introduction  
B&B Electronics 232PCC2 provides two independent RS-232  
asynchronous serial communications interfaces for systems  
equipped with PCMCIA Type II and/or Type III expansion sockets.  
The 232PCC2 is a PCMCIA Type II (5 mm) card and is PCMCIA PC  
Card Standard Specification 2.1 compliant.  
The 232PCC2's serial ports are implemented using 16C550  
Universal Asynchronous Receiver/Transmitters (UARTs) that are the  
recommended communications interface for multitasking  
environments and applications involving high data transfer rates.  
The 232PCC2’s two serial ports are addressable in two modes:  
1. Block Mode: The two serial ports are configured in one 16-byte  
continuous block of I/O address space. The block must begin  
on an even 16-byte division. Both serial ports share one IRQ  
level.  
2. COM Mode: The two serial ports are configured at the standard  
COM port I/O address location. The ports may be configured as  
COM1 and COM3; also, the ports may be configured as COM2  
and COM4. Both serial ports share one IRQ level.  
A special interrupt status register is also available to simplify the  
software required to service multiple serial ports in an interrupt  
driven environment. See the Hardware Information section for  
details.  
NOTE: When installed, a 232PCC2 appears as a DSP-100 by

Chapter 2: DOS / Windows 3.x Installation  
Two configuration software programs are provided with the  
232PCC2: a Client Driver, DSP100CL.SYS, and a card Enabler,  
DSP100EN.EXE. Both of these programs are executed from DOS  
(before entering Windows) and allow operation of the 232PCC2 in  
both the DOS and Windows 3.x environments. For optimal  
operation, however, the Client Driver is the preferred method of  
installation and configuration. The table below highlights the  
differences between these programs.

Card and Socket Services software is commercially available  
from several vendors for most desktop and laptop PCs. If you are  
unsure whether Card and Socket Services software is currently  
installed on your system, install the 232PCC2 Client Driver as  
discussed in following section. When loaded, the Client Driver will  
display an error message if Card and Socket Services software is  
not detected.

232PCC2 Client Driver for DOS  
In order to use the 232PCC2 Client Driver, the system must be  
configured with Card and Socket Services software.  
IMPORTANT:  
Some versions of Card and Socket Services dated before 1993  
do not support general purpose I/O cards. If after careful installation  
of the Client Driver the 232PCC2 does not configure or operate  
properly, an updated version of Card and Socket Services may be  
required.  
Client Driver Installation  
The following procedure is used to install the 232PCC2 Client Driver:  
Copy the file DSP100CL.SYS from the 232PCC2  
distribution diskette onto the system's hard drive.  
Using an ASCII text editor, open the system's  
CONFIG.SYS file located in the root directory of the  
boot drive.  
Locate the line(s) in the CONFIG.SYS file where the  
Card and Socket Services software is installed.  
AFTER the line(s) installing the Card and Socket  
Services software, add the following line to the  
CONFIG.SYS file:  
DEVICE = drive:\path\DSP100CL.SYS options  
where options are the 232PCC2 Client Driver command  
line options discussed on the following pages.  
Save the CONFIG.SYS file and exit the text editor.  
Insert the 232PCC2 into one of the system's PCMCIA  
slots.  
NOTE: Since the 232PCC2 Client Driver supports "Hot  
Swapping", it is not necessary to have the 232PCC2  
installed when booting the system. By inserting the card  
before booting, however, the Client Driver will report the  
adapter configuration during the boot process thereby  
verifying the changes made to the CONFIG.SYS.

B&B Electronics Ltd – Westlink Commercial Park – Oranmore, Galway, Ireland – Ph +353-91-792444 – Fax +353-91-792445  
 
Reboot the system and note the message displayed when  
the 232PCC2 Client Driver is loaded. If the Client Driver  
reports an "invalid command line option", correct the entry  
in the CONFIG.SYS file and reboot the system again. If  
the Client Driver reports "Card and Socket Services not  
found", a version of Card and Socket Services must be  
installed on the system or the 232PCC2 Enabler program  
must be used to configure the adapter. If the Client Driver  
reports the desired adapter configuration, the installation  
process is complete and the 232PCC2 may be removed  
and / or inserted from the system as desired. On each  
insertion into the PCMCIA socket, the 232PCC2 will be  
automatically re-configured according to the command  
line options.  
Command Line Options  
The 232PCC2 Client Driver accepts up to eight command line  
arguments from the user to determine the configuration of the  
232PCC2. If any arguments are provided, the Client Driver will  
attempt to configure any 232PCC2s with the options specified in the  
order they are entered on the command line. Each argument must  
be enclosed in parenthesis and must be separated from other  
arguments by a space on the command line. Within each argument,  
any or all of the following parameters may be specified using a  
comma (no spaces) to separate each parameter:  
Baddress  
specifies the base I/O address of the 232PCC2 in  
hexadecimal and must reside on an even 16-byte  
(10H) boundary. This option must be omitted if using  
the Dmode option. If both the Dmode and Baddress  
option are omitted, Card and Socket Services will  
assign a block mode base address.  
Dmode  
specifies a COM mode base I/O address configuration  
for the 232PCC2. The D1 option configures the  
232PCC2at COM1/COM3 (3F8/3E8), and the D2  
option configures the 232PCC2 at COM2/COM4  
(2F8/2E8). This option must be omitted if using the  
Baddress option. If both the Dmode and Baddress  
options are omitted, Card and Socket Services will  
assign a block mode base address.

B&B Electronics Ltd – Westlink Commercial Park – Oranmore, Galway, Ireland – Ph +353-91-792444 – Fax +353-91-792445  
 
Iirq  
specifies the interrupt level (IRQ) of the 232PCC2 in  
decimal. irq must be one of the following values: 3, 4,  
5, 7, 9, 10, 11, 12, 14, 15, or 0 if no IRQ is desired. If  
this option is omitted, Card and Socket Services will  
assign an interrupt level.  
Ssocket  
specifies which PCMCIA socket the 232PCC2 must be  
inserted into for this configuration argument to be used.  
socket must be in the range 0 - 15. If this option is  
omitted, the configuration argument will apply to the  
232PCC2 inserted into any socket.  
U
instructs the Client Driver to disable the 232PCC2's  
interrupt status register and enable the Scratchpad  
registers of the individual UARTs. This option is only  
required in very rare cases where an application  
program requires access to the UART's Scratchpad  
register. If this option is omitted, the 232PCC2's  
interrupt status register is enabled and the UARTs’  
Scratchpad registers are disabled.  
Example 1  
DEVICE = C:\DSP-100\DSP100CL.SYS  
In example 1, no command line arguments are specified. The Client  
Driver will configure a 232PCC2 inserted into any socket with a base  
address and IRQ assigned by Card and Socket Services. The  
232PCC2's interrupt status register will be enabled.  
Example 2  
DEVICE = C:\DSP-100\DSP100CL.SYS (d1)  
In example 2, a single command line argument is provided. The  
Client Driver will attempt to configure a 232PCC2 inserted into any  
socket in COM mode at COM1/COM3 and an IRQ assigned by Card  
and Socket Services. If address COM1 (3F8) or COM3 (3E8) are  
unavailable, the 232PCC2 will not be configured. If the Client Driver  
can successfully configure the 232PCC2, its interrupt status register  
will be enabled.

Example 3  
DEVICE = C:\DSP-100\DSP100CL.SYS (s0,b300,i5)  
In example 3, a single command line argument is provided. The  
Client Driver will attempt to configure a 232PCC2 inserted into  
socket 0 with a base address of 300H and IRQ 5. If address 300H  
or IRQ 5 is unavailable, the 232PCC2 will not be configured. In  
addition, if a 232PCC2 is inserted into any other socket, it will not be  
configured. If the Client Driver can successfully configure the  
232PCC2, its interrupt status register will be enabled.  
Example 4  
DEVICE = C:\DSP-100\DSP100CL.SYS (i5,e,u,b300)  
In example 4, a single command line argument is provided.  
Because the parameter order is not significant, the Client Driver will  
attempt to configure a 232PCC2 inserted into any socket with a base  
address of 300H and IRQ 5. If address 300H or IRQ 5 is  
unavailable, the 232PCC2 will not be configured. If the Client Driver  
can successfully configure the 232PCC2, its interrupt status register  
will be disabled (Scratchpad registers enabled).  
Example 5  
DEVICE = C:\ DSP-100\DSP100CL.SYS (b300,i5) (i10) ( )  
In example 5, three command line arguments are provided. The  
Client Driver first attempts to configure a 232PCC2 inserted into any  
socket with a base address of 300H and IRQ 5. If address 300H or  
IRQ 5 is unavailable, the Client Driver will proceed to the second  
command line argument and attempt to configure the card with a  
base address assigned by Card and Socket Services and IRQ 10. If  
IRQ 10 is also unavailable, the Client Driver will proceed to the third  
command line argument and attempt to configure the 232PCC2 with  
a base address and an IRQ assigned by Card and Socket Services.  
If the 232PCC2 is successfully configured, its interrupt status  
register will be enabled.

Example 6  
DEVICE = C:\ DSP-100\DSP100CL.SYS (b300,i5) ( ) (i10)  
In example 6, the three command line arguments of example 5 have  
been re-arranged. The Client Driver first attempts to configure a  
232PCC2 inserted into any socket with a base address of 300H and  
IRQ 5. If address 300H or IRQ 5 is unavailable, the Client Driver will  
proceed to the second command line argument and attempt to  
configure the card with a base address and IRQ assigned by Card  
and Socket Services. Since the second command line argument  
includes all available address and IRQ resources, the third  
command line argument will never be reached by the Client Driver.  
It is the user's responsibility to place the command line arguments in  
a logical order.  
Example 7  
DEVICE = C:\ DSP-100\DSP100CL.SYS (s0,b300,i5)  
(s1,b340,i10)  
The type of configuration shown in example 7 may be desirable in  
systems where more than one 232PCC2 is to be installed. In this  
example, the Client Driver will attempt to configure a 232PCC2  
inserted into socket 0 with a base address of 300H and IRQ 5. If the  
232PCC2 is inserted into socket 1, the Client Driver will attempt to  
configure it with base address 340H and IRQ 10. This allows the  
user to force the 232PCC2's address and IRQ settings to be socket  
specific that may simplify cable connections and software  
development. As in the previous examples, however, if the  
requested address or interrupt resources are not available, the  
232PCC2 will not be configured.

Common Problems  
Identifying the 232PCC2  
The 232PCC2 when installed shows up as a DSP-100.  
Generic Client Drivers Generic Client Drivers  
Many Card and Socket Services packages include a generic  
client driver (or SuperClient) that configures standard I/O devices. If  
one of these generic client drivers is installed, it may configure the  
232PCC2 causing the 232PCC2 client driver to fail installation. In  
these cases, the user should do one of the following:  
Modify the operation of the generic client driver to  
disable the configuration of modem/serial port cards.  
Consult the Card and Socket Services documentation  
for availability and details of this feature.  
Place the 232PCC2 client driver before the generic  
client driver in the CONFIG.SYS.  
Available Resources  
One function of the Card and Socket Services software is to  
track which system resources (memory addresses, I/O addresses,  
IRQs, etc.) are available for assignment to inserted PCMCIA cards.  
Sometimes, however, the Card Services software assumes or  
incorrectly determines that a particular resource is used when it is  
actually available. Most Card and Socket Services generate a  
resource table in a file (typically in the form of an .INI file) that the  
user can modify to adjust the available system resources. Consult  
the Card and Socket Services documentation for availability and  
details of this feature.  
Multiple Configuration Attempts  
Some Card and Socket Services have a setting that aborts the  
configuration process after a single configuration failure (such as a  
requesting an unavailable resource). The user should change this  
setting to allow for multiple configuration attempts. Consult Card and  
Socket Services documentation for availability and feature details.  
Older Versions of Card and Socket Services  
Some versions of Card and Socket Services dated before 1993  
do not support general-purpose I/O cards. If, after careful  
installation of the Client Driver, the 232PCC2 does not configure or  
operate properly, an updated version of Card and Socket Services  
may be required.

Chapter 3: 232PCC2 Enabler for DOS  
For systems that are not operating PCMCIA Card and Socket  
Services software, the 232PCC2 DOS Enabler may be used to  
enable and configure the adapter. This Enabler, DSP100EN.EXE,  
will operate on any DOS system using an Intel 82365SL or PCIC  
compatible PCMCIA host adapter including the Cirrus Logic CL-  
PD6710 / 6720, the VLSI VL82C146, and the Vadem VG-365  
among others.  
IMPORTANT  
In order to use the 232PCC2 Enabler for DOS, the system  
MUST NOT be configured with Card and Socket Services software.  
If a Card and Socket Services software is installed, the 232PCC2  
Enabler may interfere with its operation and with the device(s) it  
controls.  
The 232PCC2 Enabler does not support automatic configuration  
of adapters upon insertion, more commonly referred to as "Hot  
Swapping". This means the adapter must be installed in one of the  
system's PCMCIA sockets before executing DSP100EN.EXE. If  
more than one adapter is installed in a system, the Enabler must be  
executed separately for each adapter. Furthermore,  
DSP100EN.EXE should be executed to release the resources used  
by the adapter before it is removed from the PCMCIA socket. Since  
PCMCIA adapters do not retain their configuration after removal, any  
adapter that is removed from the system must be reconfigured with  
the Enabler after re-inserting it into a PCMCIA socket.  
IMPORTANT  
The Enabler requires a region of high DOS memory when  
configuring a 232PCC2. This region is 1000H bytes (4KB) long and  
by default begins at address D0000H (the default address may be  
changed using the "W" option). If a memory manager such as  
EMM386, QEMM, or 386Max is installed on the system, this region  
of DOS memory must be excluded from the memory manager's  
control. Consult the documentation provided with the memory  
manager software for instructions on how to exclude this memory  
region.

Command Line Options  
To configure a 232PCC2 in the system, the Enabler requires  
one command line argument from the user to determine the  
configuration of the card. This argument must be enclosed in  
parenthesis and within the argument, any or all of the following  
parameters may be specified using a comma (no spaces) to  
separate each parameter:  
Ssocket  
specifies which PCMCIA socket the 232PCC2 must be  
inserted into for this configuration argument to be used.  
socket must be in the range 0 - 15. This option is  
always required.  
Baddress  
specifies a block mode base I/O adddress of the  
232PCC2 in hexadecimal and must reside on an even  
16-byte (10H) boundary. Specify only one of the  
following three options: Baddress, Dmode, or ‘R’. Use  
of one of these options is always required.  
Dmode  
specifies a COM mode base I/O address configuration  
for the 232PCC2. The ‘D1’ option configures the  
232PCC2 at COM1/COM3 (3F8/3E8), and the ‘D2’  
option configures the 232PCC2 at COM2/COM4  
(2F8/2E8). Specify only one of the following three  
options: Baddress, Dmode, ‘R’. Use of one of these  
options is always required.  
Iirq  
specifies the interrupt level (IRQ) of the 232PCC2 in  
decimal. irq must be one of the following values: 3, 4,  
5, 7, 9, 10, 11, 12, 14, 15, or 0 if no IRQ is desired.  
This option is required if the 'R' option is not used.  
Waddress specifies the base address of the memory window  
required to configure the 232PCC2. Set address = D0  
for a memory window at segment D000, address = D8  
for a memory window at segment D800, etc. Valid  
settings for address are C8, CC, D0, D4, D8, and DC.  
If this option is omitted, a memory window at segment  
D000 will be used.  
U
instructs the Enabler to disable the 232PCC2's  
interrupt status register and enable the Scratchpad  
registers of the individual UARTs. This option is only  
required in very rare cases where an application  
program requires access to the UART's Scratchpad  
register. If this option is omitted, the 232PCC2's  
interrupt status register is enabled and the UARTs'

Scratchpad registers are disabled.  
Before removing a 232PCC2 from its PCMCIA socket, the  
Enabler should be executed to free the system resources allocated  
when the card was installed. For this operation the Enabler provides  
on additional command line option:  
R
instructs the Client Driver to release the resources  
previously allocated to the 232PCC2. When the 'R'  
option is used, any settings specified by the 'B', 'I', and  
'U'.  
Example 1  
DSP100EN.EXE  
In example 1, no command line argument is specified. The Enabler  
will report an error and display the proper usage of the command.  
Example 2  
DSP100EN.EXE (s0,b300,i5)  
In example 2, the Enabler will configure the 232PCC2 in socket 0  
with a base address of 300H and IRQ 5 using a configuration  
memory window at segment D000. The 232PCC2's interrupt status  
register will be enabled.  
Example 3  
DSP100EN.EXE (i10,e,u,b340,s1)  
In example 3, the Enabler will configure the 232PCC2 in socket 1  
with a base address of 340H and IRQ 10 using a configuration  
memory window at segment D000. The 232PCC2's interrupt status  
register will be disabled (Scratchpad registers enabled) and the  
BIOS equipment list will be updated. Note that the parameter order  
is not significant.

The 232PCC2 is identified as a DSP-100 when installed.  
Memory Range Exclusion  
The Enabler requires a region of high DOS memory when  
configuring a 232PCC2. This region is 1000H bytes (4KB) long and  
by default begins at address D0000H (the default address may be  
changed using the "W" option). If a memory manager such as  
EMM386, QEMM, or 386Max is installed on the system, this region  
of DOS memory must be excluded from the memory manager's  
control. Consult the documentation provided with the memory  
manager software for instructions on how to exclude this memory  
region.

Furthermore, some systems use the high memory area for BIOS  
shadowing to improve overall system performance. In order for the  
Enabler to operate, any BIOS shadowing must be disabled in the  
address range specified for the configuration window. BIOS  
shadowing can usually be disabled through the system's CMOS  
setup utility.  
Socket Numbers  
The Enabler requires the 232PCC2's socket number to be  
specified on the command line and the 232PCC2 must be inserted  
into the socket before the Enabler is invoked. Some vendors  
number their sockets from 1 to N while other vendors number their  
sockets from 0 to N-1. For the 232PCC2 Enabler, the lowest socket  
number in the system is designated socket 0.  
Card and Socket Services Software  
In order to use the 232PCC2 Enabler for DOS, the system  
MUST NOT be configured with Card and Socket Services software.  
If a Card and Socket Services software is installed, the 232PCC2  
Enabler may interfere with its operation and with the device(s) it  
controls. For systems configured with Card and Socket Services,  
the 232PCC2 Client Driver is the recommended method of  
configuration.

Chapter 4: Windows 95/98 Installation  
To allow easy configuration of the 232PCC2, a Windows  
95/98 “INF”configuration file has been written for the hardware. This  
configuration file supports the 232PCC2 in both addressing modes:  
block mode and COM mode.  
Installing a 232PCC2 Under Windows 95/98.  
1. Insert the 232PCC2 into any available PC Card socket.  
2. The first time a new PC Card type is installed, either the  
New Hardware Found window or the Update Device  
Driver Wizard window is displayed. After the initial  
installation, Windows 95/98 will automatically detect and  
configure the card. If the neither window is displayed, skip  
to the section "232PCC2 Resource Settings".  
3. If your version of Windows displays the New Hardware  
Found window select the Driver from Disk option button  
and click OK to continue. An Install from Disk dialog box  
should open. Insert the 232PCC2 disk, select the correct  
drive letter (generally A:), and click the OK button. Windows  
95/98 automatically browses the root directory for an INF file  
that defines configurations for the new hardware, as well as  
the required files.  
4. If your version of Windows displays the Update Device  
Driver Wizard window, insert the 232PCC2 disk into the A:  
or B: drive and click Next. Windows 95/98 automatically  
browses the root directory of A: and B: for an INF file that  
defines configurations for the new hardware, as well as the  
required files. Windows 95/98 will report that is has found  
the driver for the device, click Finish to complete the  
installation.  
During the installation process, it may be required to supply  
the computer with the Windows 95/98 CD or installation  
diskettes. The 232PCC2's serial devices will require the file  
"SERIALUI.DLL". Insert the CD or diskette and click “OK".

NOTE: If the user already has these files installed on the computer,  
or if the installation disks are unavailable, it may not be necessary to  
supply the computer with the Windows 95/98 CD or installation  
diskettes. If prompted for the disks, click "OK". A dialog box with an  
option to skip will appear. Click the "Skip" button and the files will  
not be installed. If the latest version of these files exist in the system  
directory, those files will be used.  
The 232PCC2 PC Card should now be configured and will be  
identified as a Quatech Inc-PCMCIA Dual RS-232 Serial Port Card.  
In the future, Win95/98 will automatically recognize and configure  
the 232PCC2.  
232PCC2 Resource Settings in Windows 95/98  
Windows 95/98 maintains a registry of all known hardware  
installed within the computer. Inside this hardware registry Windows  
95/98 keeps track of all of the computer's resources, such as base  
I/O addresses, IRQ levels, and DMA channels. In the case of a PC  
Card (PCMCIA) type board, Windows 95/98 configures the new  
hardware using free resources it finds within the hardware registry,  
and updates the registry automatically.  
To view and / or edit hardware devices in Windows 95/98 use  
the system Device Manager. To access Device Manager double  
click on the System icon in the Windows 95 control panel, or click  
the My Computer icon on the Win 95/98 desktop with the right  
mouse button and select Properties from the pull down menu.  
Consult Windows 95/98 on-line help for details on the use of the  
Device Manager.  
Windows 95/98 handles the 232PCC2 as a parent/child device.  
The 232PCC2 is the parent device and is listed as a DSP-  
100 under the hardware class Multi-function Adapters in  
the device manager.  
Each serial port is a child device of the parent device.  
There are 2 child COM ports for the 232PCC2 that are listed  
under the hardware class Ports (Com & LPT).

1. Select a Basic Configurations that display “No Conflicts” in the  
bottom display region titled Conflicting Device List from the drop  
down list. Some applications may not be able to access ports  
higher than COM4. To use the 232PCC2 PCMCIA serial ports  
with these applications you might be forced to remove other  
serial communications devices from your system.  
2. Windows 95/98 should have chosen an available Interrupt  
Request setting automatically when the I/O address range was  
configured by a Basic Configuration selection. This default  
Interrupt Request setting should not need changing as long as  
“No Conflicts” is displayed in the bottom display region titled  
Conflicting Device List. If you are satisfied with Windows  
95/98 selection then skip the next step.  
3. To modify the Interrupt Request setting click the resource name  
and click the Change Setting button. An Edit Resource window  
will open up. Inside this window click on the up/down arrows to  
the right of the Interrupt Request value. This scrolls you through  
all of the allowable resources for your hardware. Pay attention  
to the conflict information at the bottom of the window. Do not  
select a value that causes a conflict with any other installed  
hardware.  
4. If any changes have been made to the 232PCC2’s configuration  
the card will automatically be reconfigured to the new resources  
specified. Any time a PCMCIA card of this type is inserted  
Windows 95/98 will attempt to configure the card at these  
resource settings. Click the Use Automatic Settings box to  
reset this card type for automatic configuration.

Chapter 5: Hardware Information  
The 232PCC2’s two asynchronous serial ports are implemented  
using 2 standard 16C550 UARTs. Each of these UARTs requires 8  
bytes of I/O space and when enabled which requires the 232PCC2  
to be located on an even 16-byte (10H) boundary (e.g. 300H, 310H,  
320H, etc.).

Channel  
Address Assignment  
Channel A  
Channel B  
Base Address + 0  
Base Address + 8  
Each 16C550 UART contains 8 I/O registers. The last of these  
registers, located at (Base address + 7), is referred to as the  
'Scratchpad Register' and provides no functionality to the UART. In  
place of this Scratchpad Register, the 232PCC2 implements an  
interrupt status register which can be accessed at (Base address +  
7) of any UART. The purpose of the interrupt status register is to  
give the software programmer an easy way to inspect the interrupt  
state of the entire 232PCC2 with a single input operation. The  
format of the interrupt status register is shown below:  
D7

D6  
0
D5

D3

D2

D1  
D0  
Intr B Intr A  
When one or more UARTs have interrupts pending, the  
associated bit(s) in the interrupt status register are set to logic 1.  
When all the pending interrupts have been serviced for a specific  
UART, its interrupt status bit will be cleared to logic 0 automatically.  
When all the pending interrupts from all UARTs have been serviced,  
the entire interrupt status register will return logic 0. The application  
program should not exit its interrupt service routine until all pending  
interrupts from all channels have been serviced (interrupt status  
register = 0) or no additional interrupts will be received.  
If an application requires the UARTs' Scratchpad Registers, the  
interrupt status register can be disabled. Disabling the interrupt  
status register is supported by the 232PCC2 configuration software,  
which is operating system dependent. Refer to the relevant  
operating system installation section for specific usage of this  
feature.
