ttytype — data base of terminal types by port




ttytype is a database that identifies the kind of terminal that is attached to each tty port on the system. The file contains one line per port, and each line contains the terminal type (as a name listed in terminfo(4)), a space, and the name of the tty device file, less the initial /dev/. For example, for an HP 2622 terminal on tty02:

2622 tty02

This information is read by tset and by login (for remote logins) to initialize the TERM variable at login time (see tset(1) and login(1)).


ttytype was developed by the University of California, Berkeley.


login(1), tset(1).


Some lines are identified simply as dialup or plugboard.
