The termcap entry for terminal type ‘emacs’ is ordinarily put in the ‘TERMCAP’ environment variable of subshells. It may help in certain situations (e.g., using rlogin from shell buffer) to add an entry for ‘emacs’ to the system-wide termcap file. Here is a correct termcap entry for ‘emacs’:
emacs:tc=unknown:
To make a terminfo entry for ‘emacs’, use tic or
captoinfo. You need to generate
/usr/lib/terminfo/e/emacs. It may work to simply copy
/usr/lib/terminfo/d/dumb to /usr/lib/terminfo/e/emacs.
Having a termcap/terminfo entry will not enable the use of full screen programs in shell buffers. Use M-x term for that instead.
A workaround to the problem of missing termcap/terminfo entries is to
change terminal type ‘emacs’ to type ‘dumb’ or ‘unknown’
in your shell start up file. csh users could put this in their
.cshrc files:
if ("$term" == emacs) set term=dumb
