This is a draft I'm developing of a generic answer to a general request like
yours. It will give you an overall idea of what you need to try and, if you
run into a problem, what you will need to tell the list if you want to get
any focused help. I'd welcome comments from others on the list about how to
improve this -- I think we need a brief description of the basic steps, one
that is briefer than the Modem HowTo even at the price of its being less
thorough, since questions like this one come to the list pretty regularly
(and the Modem HowTo is somewhat tough going for a true beginner) .
Here are the basic steps to follow:
1. If the modem is internal, make sure it is NOT an HSP modem ("Winmodem").
Chack this at URL http://www.o2.net/~gromitkc/winmodem.html . In general,
pci-bus modems are almost surely HSP, while isa-bus and pcmcia modems may or
may not be HSP. No external modems are HSP. HSP modems CANNOT be used with
Linux -- if you have one, you have to replace it with something else that
will work.
2. Figure out what port the modem is connected to. If you have a PnP modem,
you may need to do some configuration work at this step; see the Plug and
Play HowTo. The presence of an internal real (non-HSP) modem will usually be
detected by the kernel, which will see it as a serial port (use "dmesg" to
review the boot-time messages from the kernel). If you've been using this
system with some version of WIndows, WinXX equivalences are:
COM1 = /dev/ttyS0
COM2 = /dev/ttyS1
COM3 = /dev/ttyS2
COM4 = /dev/ttyS3
3. Make sure you don't have a conflict with the IRQ on the port. (S0 and S2
share IRQ 4, and S1 and S3 share IRQ 3, so this is possible.) The conflicts
to watch out for are a mouse on the other serial port that uses the same IRQ
and (especially on older systems) a NIC (Ethernet card) using IRQ 3. Check
IRQ assignments with "more /proc/interrupts".
4. Use setserial to try to find the modem, by probing the /dev where you
think it is. For S0, for example, you would enter: "setserial /dev/ttyS0".
When it responds, see if a UART type is reported. If it is, you'vefound your
modem. IF not, you have a problem.
5. If you've found your modem, then make /dev/modem a symlink to that /dev .
Using S0 as an example, you would do this with the command "ln -s /dev/ttyS0
/dev/modem". (If you get a response that the link already exists, do "rm
/dev/modem" then make the symlink.)
5. Now try to use minicom to dial out to someplace. If it works, you have a
working modem.
6. If you need to go on to set up a PPP connection to an ISP (a common thing
for Linux systems), begin by consulting the PPP HowTo.
HowTos can usually be found on a Linux system somewhere in /usr/doc, but the
exact location varies by distribution and version. HowTos and mini-HowTos
can also be found on the Web at URL
