NAME

ttytype - data base def ining terminal type1 used for associating terminals with serial ports

DESCRIPTION

The ttytype data base is used to associate a manufacturer's terminal with the different serial ports on the system.

Each line contains the name of a terminal, a tab character, and then the XENIX device entry for the serial ports associated with that terminal. The terminal name must

correspond to an entry in /etc/termcap.

Making an entry in the ttytype file for your terminals allows the system to make maximum use of terminal features for certain system facilities that use full screen capabili ties. Among these programs are vi (1), bsh (1), and ua (1) •

FILES

/etc/ttytype SEE ALSO

USAGE

vi(l), bsh(l), ua(l), termcap(5)

A typical line in the tty type file might look like ndumb /dev/tty3 n or nwyse /dev/tty5.ⁿ The first says that serial port 3 is connected to a terminal described in /etc/termcap as having no special characteristics such as cursor move-ment. The second entry tells XENIX that serial port 5 is connected to a terminal manufactured by Wyse Technology that is described in termcap under the name nwyse.ⁿ The terminal name is the name found between the first and second vertical bars of the appropriate entry in /etc/termcap.
