Grex Info Item 287: stuck in all caps...
Entered by wjw on Mon Jul 1 17:05:24 UTC 1996:

i presume that when grex gets a captial letter as the first character of a 
login it assumes you are on a terminal that only puts out caps, and goes int
a mode where it reflects all characters back as caps, and when a real cap
is needed it puts a slash in front of it like /this.

so every once in a while (like right now) this happens to me due to 
line noise or something...  when this happens, how do you get it back to
normal.  i presume it's some sort of environment setting.

Yes, when a Unix system sees upper case characters in the login
id, it assumes that you're on a terminal that can only handle
upper case.

As far as I know, the only way to fix it is to log back out
and log in again normally.  One of the real Unix experts may
know something that I don't, though.

Thanks, I'll try that next time.

Hmm, I thought that "stty -lcase" would *always* do it. (unless the
line noise is so bad that you can't even enter the command. In
which case, Plan A is indicated.)

Hmm, I'm familiar with iuclc & olcuc, but not with lcase ... but I'd have
*expected* the "-" to have the reverse action of that stated.

In any case, Rob's formulation of the problem is right, not the one in the
initial question.  The whole first line received by login has to be upper case
for things to get confused.  The approach is a kludge in any case (pun not
intended); it has the unreasonable effect that you can't issue any commands
which have any uppercase components, since *everything* gets translated.
Better than no kludge at all, I guess.

Not true!  If you're in upper case mode, you can send the system
an "upper case" letter by putting a \ in front of it.

(For this, I paid U of M countless thousands of dollars...  >8)

<sigh>  Rob, I should have known that ... since that's the way it
differentiates upper & lower case on *output* - it shouldn't have taken much
of a guess to think of that.  Thanks for the correction, which may yet save
my elbow some day ...

Hey, glad to help.  You never know when you may *need* that
information.
