I'm not sure the 2 HOSTESS 8 port cards I have are identical to yours, but
all I needed to do was use setserial to get them identified. The two systems
I have them installed in are down right now, so I can't get at the rc.serial
file. E-mail me if you want the info, I may not be able to get to it for a
day or 2.
The cards I have are 8*16550A UARTS on 2 boards sandwiched together with 2
cables running out to a large box with 8 25 pin connectors. There is no
visible P/N on mine (or I missed it when I took a quick look) but the date
is 1987.

If you just use setserial it will probably use polling mode (thats what
it would do on mine anyway). If you want to use interrupt driven I/O
(which you do) you need to run a little program first to enable interrupts
on the board. I wrote a program to do this, email me if you need it.
I was going to release it, but I'm not sure if it will work on a 16-port
version, and Comtrol still hasn't gotten back to me with info.

Yep, that's the "HOSTESS 550". They came in 4, 8, and 16 port varieties.

How can you tell if it's in interrupt or polling mode?
In our setserial we specify the port and the interrupt,
and all seems hunky-dory with our 8-port controller (all 8 lines plugged
works fine ASFAIK)
What exactly does this program do?
