APPENDIX B
PC COM DEVICE
DRIVER FOR MS/DOS B.1 PCCOM Software
The PCCOM software is a high
performance, easy to use RS232/RS422 device driver for PC/486, Pentium
or compatibles. Under MS/DOS environment, you can set up your serial
ports by PCCOM device driver, and these serial ports can be treated as
COM1: and COM2: devices. The setup procedure provides flexible
functions to specify the configuration of multi-serial card, that is,
the hardware configurations of I/O port number, I/O port address,
interrupt and interrupt vector are user selectable.
After the device driver is installed, It takes over communication
between CPU and multi-serial cards such as four port card, eight port
card, ... etc. For each I/O port, the service routine handles a ring
buffer to keep track of all I/O data. Moreover, the PCCOM software
provides library routines (C, PASCAL, BASIC, FoxPro) and DOS
communication interface (DOS device driver, BIOS call) for several
access levels.
For more details, please refer PCCOM manual.
B.2 Software Installation
When the board is installed, please install software drivers as follows:
STEP 1: Prepare PCI.OPT file
ThePCI.OPT file contents are :
/B:4
/D:COM3
/P:[:4:(2k:9600:N-8-1:RTS+DTR:XON) * 4]
|
STEP
2: Prepare CONFIG.SYS file
Insert statement into CONFIG.SYS file
For
normal speed
DEVICE = PCCOM.SYS @c:\pci.opt
|
For high speed
DEVICE = PCCOMH.SYS @c:\pci.opt
|
The syntax of PnP function is
The Card_id
field is defined as 1 or 2 or 3 or 4 or nil, if you use PnP mode, just
fill nil in card_id field that like step 1, otherwise you can specify
card_id to match the card identifier switch. The Portno field is used
to specify number of ports in this adapter. The Port field is defined
as PCCOM V2.0.
If more than one PCCOM board is installed, Please repeat directive /P of the step 1.
