that are a lot of trouble to make work, if you can make them work at all.
The only problem I have had with modems on Red Hat is that most of their
tools assume you have a link in /dev named /dev/modem that points to the
proper device, and yet they never make such a link. With the ISA modems,
I just stick one in to /dev/ttyS1 (on my machine). I.e.,
ln -s /dev/ttyS1 /dev/modem
First thing to do is to read the user doentation that comes with your
modem, if any. It should tell you how to configure the thing. Many
modems have jumpers to set device address and IRQ. At least the ISA ones
do. AFAIK, the PCI ones do not need that. How do PCI modems come up
anyway? They sure do not use an RS-232 connector.
I have a USR 5610B "56K* Performance Pro Modem" PCI modem that should
work with Linux, but the computer it goes in does not work yet (no
motherboard, no processors, no memory, little things like that), so I
cannot tell you first hand.
