I've been looking through the telnetd code a lot recently as
I'm removing the pty handling and trying to replace it with something
a bit more portable. I haven't had any expericnce looking through the
client, bout I would guess the coding styles are somewhat similar.
The server tended to make a lot of BSD-specific calls, special
casing sysvish systems when they were noticed. I found several places
where it accidently forgot to use a BSD-specific ioctl for terminal
handling or something, even while using Posix termios at the same
time. (Not nearly as bad as rlogind in this regard, mind you, but
still annoying).
Because it is display related, it might be a similar problem.
Alternatively, it may be a problem with the way our autoconf
configuration is setting up the preprocessor symbols for Solaris.
Check the output of configure in that directory and see if anything
looks bogus.
Of course, these are guesses; it may just be completely
unrelated to anything any of us think of.
