Enabling Dial-In Service

Linux supports dial-in service. This means that you can call in from another computer and log in over the phone. If you have two modems and phone lines for your computer, you can log in and then either dial out on the spare phone line or use Internet services if the spare line maintains an active Internet connection.

Setting up Linux for dial-in service requires the following:

  • An incoming phone line

  • A serial port and attached modem

It also requires that you do the following:

  • Configure the modem.

  • Edit the system initialization table.

  • Restart Linux.
