Modem Jumper Question
|

| Bryan L. 2002-06-29, 5:25 am |
| I got an old ISA Modem for a friends computer. Getting it to work is
really a good lesson in resource conflicts.
The Modem has jumpers. You can either set the jumpers to PnP or
Non-PnP. I tried setting to PnP and it didn't work. (It kind of
worked, just found an unknown device).
So, I switch the jumpers to the default (pictured in the install
guide). This sets it to com2, irq3.
On bootup it has a I/O conflict with 2F8.
I want to change the jumpers to a different COM port but I don't know
how. The manual offers no help. Just shows you what the default is.
Here is a diagram of the jumpers.
: = Off
I = On
PnP Jumpers Settings
SW1 1 2 3 4 5 6
: : : : : :
Non-PnP Default
SW1 1 2 3 4 5 6
: I I : : :
There is also JP1 and JP2. These are used to switch between PnP and
Legacy.
How do I set those jumpers to a different COM Port??
Thanks,
Bryan

What kind of modem is it? If you are not sure you can look it up using
the fcc id at:
http://www.fcc.gov/oet/fccid/
Or you could just disable COM2 in the bios.
