Dudes,
I have here a COM01.SYS compatible driver that will use a third or fourth
serial port on your AT. This particular file is configured as
follows. (ie. the sample COM01.SYS driver is set up for...)
Your mouse must be on COM1 if it's a serial mouse.
Modem #1 (in my case, the external modem) COM2, IRQ3, port 02F8.
Modem #2 (in my case, the internal modem) COM3, IRQ7, port 03E8.
Following is the patch list. Use the OS/2 system command PATCH to modify
this to suit your needs. The values in () are what I have changed the
values to in this version of the driver. I am running this under 1.3,
and I haven't tested it under 2.0.
Execute this OS/2 command to patch the driver...
PATCH COM03.SYS
Address Type As delivered What is it
020D Char '1' (2) Character for device name of device A
0227 Char '2' (3) Character for device name of device B
0E05 Word 0000 (0001) Port number (0..3) of device A
0E0E Word 0001 (0002) Port number (0..3) of device B
20E8 Word 03F8 (02F8) I/O address for device A
20F4 Word 02F8 (03E8) I/O address for device B
211F Byte 00 (01) Port number (0..3) of device A
216F Byte 00 (01) Port number (0..3) of device A
20EF Byte 04 (03) IRQ level of device A
2101 Byte 03 (07) IRQ level of device B
Add this line to your CONFIG.SYS
DEVICE=C:\OS2\COM03.SYS
And you're ready to rock and roll. If you have two dual port serial cards
and a BUS mouse you can modify this driver and load it twice to support all
4 of your serial ports. Use IRQ 3,4,5 & 7.
Thanks to Wayne Conrad who's patch list I'm using.
