tset - set terminal modes

tset [-] [-r] [-e] [-E] [-k] [-d type] [-p type] [-b type] [-h] [type]

Tset causes terminal dependent processing such as setting erase and kill characters, setting or resetting delays, and the like. It is driven by the /etc/ttytype and /etc/termcap files.

The type of terminal is specified by the type argument. The type may be any type given in /etc/termcap. If type is not specified, the terminal type is read from the environment unless some of the -h, -d, -b, or -p flags are set. In this case the type is read from /etc/ttytype (the terminal code to terminal type database). The terminal id is specified by a ttyn (3) call on the diagnostic output.

If the type turns out to be a dialup and the -d flag is specified, the terminal type is taken to be the named type. Similarly, if the type turns out to be a plugboard and the -p flag is specified, the terminal type assumed is taken to be type . The same applies the the -b flag on a bussiplexer port.

On terminals that can backspace but not overstrike (such as a CRT) the erase character is changed to a Control-H (backspace). The -e flag sets the erase character to be the named character c on all terminals, so to override this option one can say -e #. The default for c is Control-H. The -k option works similarly, with c defaulting to Control-X. No kill processing is done if -k is not specified.

The - option prints the terminal type on the standard output.

The -r option prints the terminal type on the diagnostic output.

Tset is most useful when included in the .login file executed automatically at login, with -d used to specify the terminal type you most frequently dial in on.
