APPENDIX B
PCCOM98 DEVICE DRIVER FOR MS/DOS
B.1 PCCOM Software
The PCCOM V2.0 is a high
performance, easy to use RS232/RS422 device driver for PC/XT, PC/AT,
PC/386, 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.
The PCCOM V2.0 is an upgrade
version of PCCOM V1.0 software, it combines with PCCOM V1.0 and SERIAL
DRIVER utilities. Each serial port may be either 8250, 16450, 16550, or
16650 chip that was detected automatically.
For more details, please refer PCCOMV2 manual.
B.2 Hardware Configuration
B.3 Software Installation
When the board is installed, please install software drivers as follows:
STEP
1: Prepare PCCOM2.OPT file
The PCCOM2.OPT file contents are :
/B:2
/D:COM3
/A:[5:2A0,1,0,LO:(2k:9600:N-8-1:RTS+DTR:XON) ],
[10:2A8,1,0,LO:(2k:9600:N-8-1:RTS+DTR:XON) ]
STEP 2: Prepare CONFIG.SYS file
Insert statement into CONFIG.SYS file
DEVICE = PCCOM.SYS @c:\pccom2.opt
The PCCOM2.OPT file contents are :
/B:2
/D:COM3
/A:[5:2A0,1,0,LO:(2k:9600:N-8-1:RTS+DTR:XON) ],
[10:2A8,1,0,LO:(2k:9600:N-8-1:RTS+DTR:XON) ]
STEP 2: Prepare CONFIG.SYS file
Insert statement into CONFIG.SYS file
DEVICE = PCCOM.SYS @c:\pccom2.opt
If more than one PCCOM board is installed, Please refer to PCCOMV2 manual.
