>From BUGS.TXT and the BUGS page in the HTML Manual:
253. HINT: Using SCOANSI emulation with SCO hosts
There is a type of terminal emulation commonly called ANSI, which is
used by BBS's. It is very simple -- essentially nothing more than
what you get with ANSI.SYS on a PC. Then there is the highly evolved
and complex version of it used on the SCO (and Linux) console. Kermit
95 supports both; the first emulation is called ANSI; the second is
called SCOANSI. However, the *name* SCOANSI is unknown on SCO
systems. They call it just ANSI. So if a Telnet client such as
Kermit 95 comes in announcing its terminal type as SCOANSI, the SCO
host doesn't recognize it. In Kermit 95 1.1.8 and later, the Telnet
terminal-type negotiation feature will cause Kermit 95 to change to
another terminal type, most likely "plain old" ANSI. To work around
this problem in Kermit 95:
set terminal type scoansi
set telnet terminal-type ansi
set terminal character-set transparent
Or on the SCO system:
Copy the /usr/lib/terminfo/terminfo.src entry for ansi to an
scoansi.src file, changing "ansi" to "scoansi" in that file, and then
run tic on it. In /etc/termcap, add "scoansi" as an alternate name in
the "ansi" entry.
SCO will add "scoansi" as an official terminal type (or, more
precisely, a preinstalled synonym for what it now calls "ansi") in its
next OpenServer release. (However, as of OSR5.0.4, they have not yet
done so).
