There is more than one potential problem - here're a few:
ncurses' default configuration doesn't support 256 colors ("only" 16,
which was more than the standard 15 years ago). It supports 256 colors
as a binary-incompatible extension of ncursesw, which could be provided
in a port. With/without the extension, infocmp would show the 256.
zsh may be looking in the termcap interface, which iirc on FreeBSD is
using a separate database.
FreeBSD may still be using a tput that's not based on ncurses.
"145" is puzzling here, too.

That works better in a couple of ways, so I'll go with that. I do, however, still have one small problem. I can't seem to get mutt to see that my urxvt has 256 colors enabled. infocmp shows "colors#256" for rxvt-256color, but if I do 'export TERM=rxvt-256color' then zsh complains "can't find terminal definition for rxvt-256color" (though it lets me set it anyway).

It was WITH_SLANG, not WITH_MUTT_SLANG. That solves the problem, and has the added benefit of being able to use my default text color (SpringGreen) instead of having to stick to the 8 normal colors. I thought that might have also opened up urxvt's 256-color support, but mutt still thinks I have only 8 colors. At least I can default to my urxvt settings for normal text, though.

You could build mutt with 'slang' support instead of ncurses. Put the
following in /etc/make.conf:
.if ${.CURDIR:M*/mail/mutt}
WITH_MUTT_SLANG=yes
.endif
OTOH, I'm using mutt-devel built with the system ncurses library
(libncursesw.so.8) in an rxvt-unicode terminal window without problems. I do
have 'LANG=en_US.UTF-8' and 'LC_ALL=en_US.UTF-8' set in my environment, 'set
charset="utf-8"' in my ~/.muttrc and am using the
'Rxvt*font: -misc-fixed-medium-r-normal--14-130-75-75-c-70-iso10646-1' font
set in ~/.Xresources.

Thank you - this is probably the incantation I need along with the

Yes it is certainly possible, i have done this recently myself and like
you i couldn't find how to do it in any man page. Fortunately i could find
the answer in the xorg-server source code.
You just open one of the virtual terminals and issue the VT_ACTIVATE
ioctl:
fd = open("/dev/ttyv9",O_RDONLY);
ioctl(fd,VT_ACTIVATE,10);
> and then use this as the display page.

Well, the above code only switches the active vt...
If you want your program output to go to a certain vt you probably have
to open the specific vt and replace the stdin and stdout file descriptors
of your program with the one of the one of the vt you just opened.
But there are probably some caveats to this method, so best is to take a
look at the getty source code and maybe add your program to /etc/ttys.

It must be possible, because it's what xdm (the X-windows login screen) does. Check out the ttyv8 line in /etc/ttys. (xdm puts the vt into a graphic mode rather than leaving it in text mode, but the allocation and control issues are presumably similar.) ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
