Recently having installed 2.2.6, I have noticed a problem with
terminal settings.
Xterm is being run from a second machine (OpenBSD 2.1 on Pmax
hardware), invoked from a window manager running on X11R5 there,
although the xterm is X11R6. (This is the normal configuration for
this machine/OS).
xterm is started with a line like so:
xterm -T "Castor" -n "Castor" -wf -e rlogin -8 -l username castor
I.e., xterm is executing on the pmax.
When the rlogin completes on host castor (the Freebsd host),
/sometimes/ the LINES variable is set to 24, which agrees with the
size of the window. At other times, it is set to a larger value,
namely 65. This is unpredictable, sometimes occuring in several
successive openings, sometimes not being seen for days. The 65
value is the one listed in /etc/termcap under xterm, "li:65". In
all cases, the TERM variable is correctly set to xterm.
The same invocations of xterm have always returned a consistently
correct LINES setting when the rlogin host was Linux or NetBSD.
An obvious workaround is to alter /etc/termcap to the "old" li:24
entry, and I would like to do that. But F'bsd uses an unfamiliar
(libmytinfo) terminal info system, that combines terminfo and
termcap in a single /usr/share/misc/termcap.db, the interface to
which I incompletely understand to be tconv. But is there a fix?
What is the righteous procedure to change the definition of xterm,
so that it is reflected "everywhere"? (i.e. so that all apps get
the li:24, regardless of whether the app queries via a termcap
routine or a terminfo routine).
Ah, yes, the shell in use on the FreeBSD is bash 2.02. (The problem
was evident with 2.01, as well). Could this be a bash problem?
TERM=${TERM:-cons25} appears in user's .profile
I have commented out these lines:
# make mail(1) happy:
# export crt=24
since I do not care about mail's mood, and have no idea what crt
is about, and do not export variables I have never seen before.
