To all the Xenix people out there: I am looking for a used but working 4 or greater port serial card. It doesn't necessarily need to be smart. However, I would like to have the docs and xenix 2.3.2 drivers. Also, I would prefer the db-25 connectors and modem control lines. One other thing, I have a card having two serial ports which can use irq lines 2 3 4 and 5. I looked in the mkdev serial stuff and there are provissions for com3 and com4. So, I added 2 entries in the sioconf.c file. com3: irq5 minor4 com4: irq2 minor12 I also replaced the irq3 and irq4 (33 34) entries in the master file with 5 and 2. Since the parellel driver likes irq5, i replaced this with 0 and put 1 in the second column. I then typed make. after linking, I copied the new file to /xenix.test. When rebooting, I got the message bad magic number. after booting with /xenix, i copied /xenix to /xenix.try and removed /xenix.test. When booting xenix.try, I still got bad magic number. Since xenix.try is a copy of xenix, I figured it would reboot ok. I even tried branding xenix.try but, to no avail. Lastly, I reinstalled the link kit (no effect). If anyone can inform me as to the cruel and enjust punnishment I have enflicted upon my computer or maybe help me with a serial card, I would sure appreciate it.

However, I would like to have the docs and Here is my 2 cents - I would suggest the Digiboard dumb board. The 16450's are socketed so at which time SCO updates the driver with FIFO support, you could replace the chips with 16550A's. The key it to use the SCO asy driver which works quite well. I tried using the Digiboard smart (12.5 mhz) as well as the CompuTone smart board with the provided drivers - and neither board worked well with bi- directional communications with modem control (all my ports are using for high speed modems). I currently am using a Hostess board which works just fine.
