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
Quatech, Inc.

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.
Table 1. Client Driver vs. Enabler for DOS/Windows 3.x.
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 [phone] – Fax [phone]
•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 [phone] – Fax [phone]
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'

B&B Electronics Ltd – Westlink Commercial Park – Oranmore, Galway,Ireland – Ph [phone] – Fax [phone]
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.

Example 4
DSP100EN.EXE (s0,b300,i3,wd8)
In example 4, the Enabler will configure the 232PCC2 in socket 0
with a base address of 300H and IRQ 3 using a configuration
memory window at segment D800. The 232PCC2's interrupt status
register will be enabled and the BIOS equipment list will not be
updated.
Example 5
DSP100EN.EXE (s0,b300,i5,r)
In example 5, the Enabler will release the configuration used by the
232PCC2 in socket 0 using a configuration memory window at
segment D000. The base address and IRQ parameters are ignored
and may be omitted.
Example 6
DSP100EN.EXE (s1,r,wcc)
In example 5, the Enabler will release the configuration used by the
232PCC2 in socket 1 using a configuration memory window at
segment CC00.
Common Problems
Identifying the 232PCC2
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.

B&B Electronics Ltd – Westlink Commercial Park – Oranmore, Galway,Ireland – Ph [phone] – Fax [phone]
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

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.
