Configuring Your Modem
Your modem is a peripheral device to Linux, like a CD-ROM drive,
hard drive, or a mouse. Your modem will be connected to a serial port,
which means that one of the serial devices in the
/dev directory actually points to your modem. You
may notice that there’s also a file,
/dev/modem, which serves as a placeholder for
your modem. Initially this file doesn’t point to anything. To
simplify your operations, so that applications like
minicomand seyon need only refer
to /dev/modem, you can create a symbolic link
from the serial device connected to your modem to
/dev/modem.
To do so, login as root and issue the command:
ln -sf /dev/ttySX /dev/modemwhere X is replaced by the number
corresponding to the serial device that points to your modem. Table 11-1 shows how the proper command
corresponds to the device by which your modem is known user DOS and
Linux.
