XThis is hacked version of the "vtem" program. It is intended to
Xwork on the AT&T Unix-pc and provides a vt100 terminal emulation.
XIt has been enhanced to handle the alternate character set of
Xthe vt100. Other than the alternate character set it should work
Xfine on any unix machine. To test it cat the file test.cat.

X.TH VTEM 1 1986-01-24
X.SH NAME
Xvtem - a VT100 emulator based on termcap
X.SH SYNOPSIS
X.I vtem
X.SH DESCRIPTION
X.I vtem
Xruns on BSD4.2 and works by starting a sub-shell and then translating
Xoutput escape sequences. It's function is limited by the capabilities
Xlisted in the termcap database and the capabilities of the actual
Xterminal that it is being run on.
X
XIt has been tested with Per Lindberg's excellent verifier "vttest" and
Xhas been found to give acceptable results on the following terminals:
X
X Sun windows
X.br
X PC-Kermit in h19 emulation mode.
X.br
X VT100 (!)
X
XOn a Sun, you can use the following Suntools rootmenu entry:
X
X.nf
X"VT100 Tool" shelltool -Ww 80 -Wh 24 -Wl " VT100 Tool" vtem
X.fi
X.SH BUGS
XRelease 1.0 of vtem has the following bugs and limitations:
X
XRegion scroll will only work on terminals with
Xcs or al/dl.
X
XIt will never write in the last position of the screen,
Xbecause of the unpredictable behaviour of many terminals.
X
XVT102 capabilities are not yet implemented.
X
XNo soft scroll.
X
X132 width not supported.
X
XInput is not translated, which means no function key emulation.
X
XNo double height or double width lines.
X
XNo alternate character set, meaning no graphics.
X
XNo printer support.
X
XNo status reports, answerback messages, etc.
X
XNo SETUP mode.
X
XNo LEDs.
