These modems are
cheap because they have very little functionality, and they require the
computer to make up for their shortcomings. Unfortunately, this means they
are complex to program, and manufacturers generally do not make the
specifications available for developers.
If you have a modem with its own on-board circuitry or an external modem,
you should have no trouble at all.
On GNU/Linux systems, the serial ports are referred to as /dev/ttyS0,
/dev/ttyS1, and so on. Your modem is almost certainly connected to either
port 0 or port 1, equivalent to COM1: and COM2: under Windows. If you
don't know which your modem is connected to, run the program wvdialconf to
try to detect it (see below); otherwise, just try both and see which
works.
If you want to talk to your modem or dial your ISP without using PPP, you
can use the minicom program. You may need to install the minicom package
to make the program available.
The Easy Way: wvdial
The simplest way to get PPP running is with the wvdial program. It makes
some reasonable guesses and tries to set things up for you.
