I know about the problem with the CHASE serial boards. I have had a
CHASE AT8 for about 5 month. Within this time nobody was able to get
it run under the MircoPort or Interactive UNIX ond the iPAX386.
I always got the same message  "Card is not installed" or
"Card is not responding". You should note that there is a new driver
on the market 3.09 I got from Specialix, but it does not work as well.

I tried out all kind of Interrupt and DMA jumper combinations, but this
did not help. The failure must be in the device driver NOT in any kind
of hardware or clock-rate due I ran the board under XENIX-286 on the
same machine. Even there it was not running as well as I wanted to have
it. I noticed that the AT8 does not even have modem control lines.

The best way is to send back the board to Sphinx. I now have an
Computone board (Intelliport 16) it is priced at about $1000 with 16
ports. For the CHASE AT8 they wanted to charge me $1300 ! The Computone
is very very good. It has LEDs and jumpers for standalone diagnostics, 
128-256 KRAM, an iAPX186 at 10MHz on board and a i8031 inside an external box.
The hardware wiring is done much better due to an outside box. Your can
program any port for modem control and best off all is the device driver.
The driver is able to allow two virtuell terminals on each serial port also
you can setup an exchange table for each function key, replace character sets
and setup control-sequenzes for your printer and and and...

All I keep from the CHASE AT8 are the expensive long-distance calls to Sphinx
or Specialix and the unreliable support over there.
