I'm having a hard time getting telix to work with COM3
on my PS/2 386.  COM1 and COM2 work, but COM3
just doesn't exist to telix.  Com1 is on the mother
board and Com2/Com3 are a dual async card.  This
is a real IBM card and it works with windows 3.0 terminal,
kermit 3.01and the wincomm demo.

In kermit I just use:
set port 3
set baud 2400

and it works!  Terminal and wincomm were even easier.
Telix wants the base address and irq #, but I haven't been
able to find a pair that works.  The default 3e8 / 4
sure doesn't.  I also tried 220 / 4 and 220 / 3.  Somewhere
I heard that the PS2 used 220 for the base address.  What
am I doing wrong?

With debug I get:
-d 40:00
0040:0000 F8 03 F8 02 20 32 00 00 - xx xx xx xx xx xx

I did try 3220 / 4 as well.

Nothing works.  How is kermit working?

Thanks,
Mark
