I certainly haven't seen that sort of trouble, but it puts me in mind of a
problem that I *do* run across sometimes - that the console driver doesn't
get reset between logins.  For instance, if I run a program that sets a
restricted scrolling region, and that program core dumps (or more likely,
if it is on another system and the telephone line hangs up), I would expect
to be able to log out and log back in and have the console back in a normal
mode.  Not so.  Perhaps someone at Microport could fix this.

Why do you do that?  You should claim to be an ansi.

The ansi terminfo entry that comes with 2.3 is defective.  I posted a fixed
one a month or two ago.  Don't disable these things, fix them!  I don't know
about the one on Microport's BBS, but the values I use are:

 hpa=\E[%i%p1%dG	(addition of %i)
 vpa=\E[%p1%dd
 ll=??			(what is ll??)

I'm using a modified ansi terminfo entry without any trouble at all.  The
full entry is:
