terminal emultators

[Sam Carleton]

I have been using VanDyke's SecureCRT for a while now
as the primary terminal to my NetBSD machine. Today
I discovered that it will display color for me when
I tell it to use the Linux terminal type.

Now, vim seems to work fine, as does many other apps,
but when mutt displays messages in threads, the
characters used nolonger looks like the little
arrows they use to look like. I was wondering if
there is some way to fix this for mutt and other
app that would have the problem?

I have been using VanDyke's SecureCRT for a while now as the primary
terminal to my NetBSD machine. Today I discovered that it will
display color for me when I tell it to use the Linux terminal type.

secureCRT reports its term type as vt220, which is a black & white
terminal. the color version in the vt220-series (according to
http://vt100.net/) was vt241, but that terminal type doesn't appear to
be in either terminfo or termcap as distributed by NetBSD.

TERM=xterm-16color gives color with secureCRT set to vt220.

Now, vim seems to work fine, as does many other apps, but when mutt
displays messages in threads, the characters used nolonger looks like
the little arrows they use to look like. I was wondering if there is
some way to fix this for mutt and other app that would have the
problem?

what you normally see with secureCRT set to vt220 under mutt are not
supposed to be little arrows: they're line-draw characters -- the
arrowheads shouldn't be there.

this gets even screwier with secureCRT set to linux, which uses IBM
character set if I'm not mistaken.

I thing what secureCRT really wants to be is a vt340 or vt340+, which is
color and uses ISO Latin 1 encoding. vt241 would work too, if secureCRT
can actually get their character mapping straightened out. a workaround
would be to allow the user to change the TERM string passed to the
server when opening a session.

likewise termcap and terminfo should add color for vt340, and an entry
for vt241. (I guess I should file a PR...)

Yes and no. The Vt241 have four colors, but you don't select them with the
ansi attribute escape sequences... (and neither on the VT340 which have 16
colors).

Unless you really check out how to select different colors, don't do
this. They don't support the ansi color attribute sequences.

wow. so there were never any VT-series terminals which had ansi color
support?

time to pester the makers of secureCRT to get their TERM setting
straight... ;)

I seem to remember that the VT500-series finally supports this.

There are, unfortunately, very few good terminal emulators. I still use
KERMIT, which is definitely the best I've found.

in securecrt, just change the font to 'vt100' or terminal

make sure $TERM is set to xterm-color

Other people have suggested ways of setting the proper terminal type,
and I'm sure that is the "correct" way of fixing it. But for the sake
of completeness, if you were to encounter a terminal emulator that just
did not have the modes you need to display those "arrows" correctly, in
mutt you can set the "ascii_chars" variable which should work with any
terminal type. They don't look as good as the normal drawn-characters,
but they'll work everywhere. HTH.
