TTYTYPE(5)						     Linux Programmer's Manual							TTYTYPE(5)

NAME

       ttytype - terminal device to default terminal type mapping

DESCRIPTION

       The  /etc/ttytype  file associates termcap/terminfo terminal type names with tty lines.	Each line consists of a terminal type, followed by
       whitespace, followed by a tty name (a device name without the /dev/) prefix.

       This association is used by the program tset(1) to set the environment variable TERM to the default terminal name for  the  user's  current
       tty.

       This  facility was designed for a traditional time-sharing environment featuring character-cell terminals hardwired to a Unix minicomputer.
       It is little used on modern workstation and personal Unixes.

FILES

       /etc/ttytype
	      the tty definitions file.

EXAMPLE

       A typical /etc/ttytype is:

	      con80x25 tty1
	      vt320 ttys0
