Is there anything I should fix in xterm termcap? On the remote machine place the same line into your .profile. For example, my .profile has the following stuff in it: if [ "$TERM" = xterm -a "`tty`" != "not a tty" ]; then echo "sizing terminal...\c" eval `resize -u` echo "done" fi This even works when connected via serial lines (cu) to other systems (assuming you have those lines in the .profile file on the system you are connected to). -- Conor P.

My Unfortunately I'm not a termcap hacker so I can'te tell you how to write a fixed termcap. However, I have the same problem under Esix and I can "fix" it by setting the environment variables COLUMNS and LINES to the sizes after you resize your xterm. ...Martin Martin Schedlbauer (mschedlb@ulowell.edu) Institute for Visualization and Perception Research Department of Computer Science University of Lowell, Lowell, MA 01854 (Tel: (508) 934-3612)

My >TERM is set to xterm. Why is this so? My sparc station doesnt seem to do >this at all. Your TERM variable, in this case, doesn't matter. Under BSD-based systems (and some SysV systems, but not all, by any means), resizing a window causes the window program (xterm, in this case) to send a SIGWINCH to the process group running in that window; if the program has been written to accept it, it will then do an ioctl(fd, TIOCGWINSZ, &buf) to get the size of the window. (I think that's the ioctl.) However, SysV does not have this for normal pseudo-tty's (which is what most xterms use). The STREAMS-based ptys, which are unsupported (and, I believe, undocumented), *do* support the necessary ioctl, but I don't know of any X implementation that uses them. > Another problem is that if you do rlogin and then vi on the >remote machine from an xterm, the vi window is always 25x80 no matter >what size your xterm is. Is there anything I should fix in xterm termcap? export LINES=<lines> COLUMNS=<rows> SCO ships a program called resize, which I tend to use as eval $(resize) (I use ksh); this spits out a TERMCAP, I believe, as well the LINES and COLUMNS variables. (I don't know if resize is a standard program or not.) Note, however, that you would have to quit vi to take advantage of a resized window. -- Sean Eric Fagan | "I made the universe, but please don't blame me for it; sef@kithrup.COM | I had a bellyache at the time." -----------------+ -- The Turtle (Stephen King, _It_) Any opinions expressed are my own, and generally unpopular with others.

Speaking of weirdness with xterm... I am running ESIX Rev D with the Motif package. When I send mail from a normal shell, the mail header shows it as being sent by me. If I send the same mail from an xterm window, it shows up as sent by root. Any ideas? -- Dan S.

I also do rlogin from one UNIX machine to another all the time. I always can at least manually tell vi, emacs, less, more etc to adjust to the right window size by typing (or including in appropriate login initialization files, depending your shell): stty cols c# rows r# [enter] where c# is the desired column number (100 for example) r# is the desired row number (42 for example) Hope this helps Regards Chin Fang Mechanical Engineering Department Stanford University fangchin@portia.stanford.edu

Since they are not supported, vi, more, and all other utilities distributed by the vendors (well, SCO and AT&T at least) do not support it; I can make emacs and less support it, but it would be futile, since only the STREAMS ptys would allow the ioctl. Instead, use the LINES and COLUMNS variables; terminfo utilities, at least, will use this; I forget whether or not termcap checks it. -- Sean Eric Fagan | "I made the universe, but please don't blame me for it; sef@kithrup.COM | I had a bellyache at the time." -----------------+ -- The Turtle (Stephen King, _It_) Any opinions expressed are my own, and generally unpopular with others.
