TTYTYPE(5) File Formats Manual TTYTYPE(5)
ttytype - data base of terminal types by port
Ttytype is a database containing, for each tty port on the system, the
kind of terminal that is attached to it. There is one line per port,
containing the terminal kind (as a name listed in termcap (5)), a
space, and the name of the tty, minus /dev/.
This information is read by tset(1) and by login(1) to initialize the
TERM variable at login time.
Some lines are merely known as "dialup" or "plugboard".
