In each window
screen opens, it sets the
screen by default, unless no description for
screen is installed in the local termcap or terminfo data base.
In that case it pretends that the terminal emulator is ‘vt100’.
This won’t do much harm, as
screen is VT100/ANSI compatible. The
use of the
term command is discouraged for non-default purpose.
That is, one may want to specify special
$TERM settings (e.g. vt100) for
screen rlogin othermachine command. Use the command
screen -T vt100 rlogin othermachine rather than setting
and resetting the default.
