Hi,

I have been trying to add a 28.8k internal modem to my (Linux) PC box,
with no success so far, and I'm starting to wonder if it's even
possible.

The first thing I thought I would try was to just replace the old 14.4k
card with the 28.8k, to make sure the new card worked.  This is not
working.  The docs for the new card say that COM3/IRQ5 is really COM7.

I don't know what that means.  Is it COM3 or COM7?  And how do I change
which /etc files to reflect that difference.

Furthermore, when I tried to disable the second serial port on my I/O
card, and have both internal modems installed at the same time, there
seems to be some kind of IRQ contention, even though I thought that was
sorted out.

Here is my current configuration, I think:

I/O card:
   serial port 1:  COM1 / IRQ 4
   serial port 2:  disabled (no jumper, instead of selecting COM2 or COM4)
   printer IRQ:    7

Internal modem 1 (14.4k):
   COM3 / IRQ5

Internal modem 2 (28.8k):
   COM2 / IRQ3

When I boot up, the keyboard eventually locks up, and screen save is not
working, so I think the OS is completely hung.  If I remove the new
card, I am back to normal.


So, does anyone have any experience/advice about this?


thanks,
tw
