From: secsu@ariel.lerc.nasa.gov (Ralph O. Clark) Subject: vt100 emulation, garbaged screen Date: 12 Feb 1993 17:43 EST
Greetings.
I was logged in to a remote system and inadvertently sent a binary file
to my screen (under Kermit, SLS 0.99pl4). The most immediate result
was that, from that point on, that virtual console mapped characters
very oddly. My screen was full of box-drawing characters and other
nonsense. Some non-alphabetic characters (such as the kermit prompt '>'
and the shell prompt '#') were preserved, as well as upper-case letters,
but the rest was nonsense. I couldn't find an option to setterm to
restore normal operation.
The other result was that, when I used ps to find the pid of that session
so I could kill it, ps printed out the expected stuff and then dumped
core. Actually, I don't know if this was a result of the garbaged screen
or not. My system has been running for about 10 days without rebooting.
I guess I could use gdb on the core file, but what I really want is
some explanation/solution to the screen garbage problem.
ad(thanks)vance.
