Chapter 1: Terminals and Modems

This chapter describes some of the software and hardware considerations for setting up terminals and modems. This information also applies to most generic serial devices. It does not cover specialized devices (such as the Dial & Button Box and the Spaceball). For more information on these devices, please contact Silicon Graphics. "Dumb" serial printers are also connected using the TTY subsystem, but they are covered in Chapter 2, "Printers."

Serial communication between users and serial devices, such as modems and terminals, is supported by the TTY subsystem. This chapter tells you how to administer the TTY subsystem with respect to terminals and modems. It includes information about:

How the TTY subsystem works. See "About the TTY Subsystem".
Connecting an ASCII terminal. See "Installing an ASCII Terminal".
Connecting a modem. See "Installing a Modem".
Information on managing the TTY subsystem. See "Managing the TTY Subsystem".
Serial port cabling and pin signals for the standard serial ports. See "Serial Port Pin Signal Tables".

To connect peripherals that are not covered in this chapter, refer to the documentation that accompanies the peripheral.
