NAME

tset − set terminal modes

SYNOPSIS

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

DESCRIPTION

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.
