Every system needs one

Answer #1:
Driver version mismatch. Using a Xenix 2.2.0 or greater driver with
a pre 2.2.0 Xenix or vice-versa is a no-no.
SCO changed the size of the CLIST struct when it changed from
2.1.3 to 2.2.0.
Call concensus and verify your drivers. This problem occurs with
ALL 'intelligent' I/O boars using DMA to blow data directly into the CLISTs.
Answer #2:
If a "blue AT" is a fast, old box (16-20MgHZ 386 or 12-16MgHZ 286)
then you MUST use update 'K' of 2.1.3.
Answer #3: (best bet)
Update your Xenix and drivers to the most recent matched versions.
Not only will your system now work, but you will cure some fairly serious
bugs involving modem-control ports, the partial open hack, and Xenix 2.1.3.
