=>OK, I just tried to reproduce the results under OW 2.0 and 3.0, but it

=>and I'm currently experiencing it under X (from MIT, X11R4), so I assumed
=>the problem was present under OW also.

=>I have been able to reliable reproduce the results under X and Sunview,
=>but only under certain circumstances.  Here's what I do:

=>1)  Start up X or sunview

=>2)  In addition to whatever xterms or cmdtools (or shelltools) opened
=>    when you started X or sunview, respectively, open two more.  For
=>    example, say that you started X with two xterms which use /dev/ttyp0
=>    and /dev/ttyp1.  You want to open two more xterms so that they
=>    use ttyp2 and ttyp3.

=>3)  Resize the first of the two windows you opened in 1) (the xterm
=>    using ttyp2 in the example above).  stty -a should reflect the new size.

=>4)  Exit the window which you just resized (ttyp2)

=>5)  From any of the other windows (or from another machine), telnet
=>    into the machine so that your login uses the same ttyp used by
=>    the window you just resized and quit (ttyp2, in this example).

=>6)  If you now type stty -a, the number of rows and columns reported
=>    will match the size of the window you had just resized and quit.

=>Observations:

=>  Assume ttyp(n) is the ttyp which has be resized for the following:

=>  -I see this behavior only if ttyp(n+1) is in use.  For example, say
=>   ttyp0, ttyp1, ttyp2, ttyp3 and ttyp4 are in use.  This behavior
=>   won't be seen if ttyp4 is the one resized.  It will happen if ttyp2
=>   is the one resized.  ttyp(n-1) may also have to be in use, but I
=>   haven't tested this in all cases.  (Hey, I've got work to do!! (-: )

=>  -It seems that this only happens with even numbered ttyp's, but again
=>   I haven't tested this extensively.

    Hmm,
    I have a 4/490 running SunOS 4.1.1 which is forever getting what I
    call 'whacked out ptys'.  Seems to always be even numbered ptys.
    Typically 0 but sometimes 6.  Sometimes you can't even login on the
    telnet port.  After entering your password it just says 'connection
    closed'.  Other times the terminal is in noecho mode.  Other times
    it is in the mode where you get no <CR> just linefeeds across your
    page.  If anyone knows of a patch I'd really like to hear about it.

    Email please I don't get to gnus as often as I'd like.
