We have a computer here in lab that needs com port help.
The 1st com port is working, but the second is not.
Both com ports are running from a card, labeled as
follows: (PTI-2278 FCC ID: ID2-W837575) It's an old ISA
card, which sockets into one slot, and then occupies
another card spot with 2 other comm ports connected by
ribbon cables. (for a total of 4 com ports, 2 male and
2 female) The hard drive and the floppy drives are both
running through this board. Evidently the current pin
setting disables com2 so a modem can be run. We no
longer need the modem, but we need the com port. What
I need is the jumper setting. (there are 9 jumper
locations, all in a row, 4 of which are jumpered now.)
Anyway, If anyone has the jumper settings for this board,
I'd really appreciate it. If possible, could I get an
email response?

I found your jumper settings; they are contained in
a demo version of a program called Support Source
from Micro House. The card you have is listed as a
Kouwell kw556n controller card (Winbond bought
Kouwell). You can download the program at:
Look for the 7 day trial version of the Micro House
technical library.

Try putting all jumpers on the top position (1-2).

What you have is called a multi i/o controller card.
It was made by Winbond in 1992/3. They provide no
support for this card on their site, however, an e-mail
to support might yield results as far as jumper
settings are concerned. Try:
The card probably has five separate pinouts:
IDE, Floppy, Com1, Com2, and Game,plus an LPT1
(parallel) port wired directly to the back of the
card. Com1 is for your mouse. Com2 is probably the
25 pin female connector that is on the outboard
connector plate. Set your modem to com3 if you can,
or remove it altogether.
Run msd.exe from real-mode dos to see if com2 is
present (click on "ports"). If it's there, see IRQ
for info on which interrupt com2 is using, and set
the driver for your serial device to match. If it
is not present, then your com2 probably is disabled.
If you can't get the jumper settings for this card,
try trial and error. Just make sure that you write
down the current settings so that you can always
return to the original configuration. In any case,
controllers are cheap. You can probably get a used
one for $10-15 and save yourself a lot of time and
