Hello,
I have an Ultra 2 server, and I use it in standard text mode (no GUI).
The problem is that some times, but not always, after quitting the
Veritas Netbackup 'bpadm' menu interface, the terminal starts to behave
strangely.
When typing UNIX commands and looking at the standard output, the
text first runs to the bottom of the screen, which is normal, and then,
instead of shifting each line up one space (and losing the top line) to
display the new line, it shifts everything about 15 lines up and runs to
the bottom of the screen again, to shift 15 lines up again and so on.

I tried to change 'stty' parameters to see what happens, but nothing
happens. I'm even unable to change 'rows' and 'columns' parameters. stty
seems to accept the value I give to these parameters, but when I type 'stty -a'
afterwards, I see it's keeping the old values of 34 rows and 80 columns and
never accept my values.

Now, just rebooting the machine will return to normal, but I'd like to see
and understand what's happening and fix the problem, without having to
reboot, because some of our servers can't reboot at any time.

Thanks for any help.

Louis-Luc
