I would like to be able to send a one line message to all users but for that
message to appear on a specific line so that the user's vt200 screen isn't
corrupted.

Is there any way of using e.g. wall to do this?

TIA

Stephen

You might be able to use wall if you send the appropriate VT200 ESC
sequences. Just a thought.

Does ^L work on the terminals? If so, just mention in your message
for the user to use ^L to rerender the screen.

If everyone has the same terminal type (vt200) you can
embed some escape sequences, like someone else mentioned.
I'm not sure if you can do this via wall or not. But
the vt200 has good save and restore cursor sequences. These
are a big help.

We have a product called PEEK that lets you see what someone
is doing and type on their behalf (remote support, demos,
that kind of thing). We embedded in there a thing called
"status line message". We stuff the escape sequence in the
user's buffer and can do what you want, and can handle
different or mixed terminal types. You can get details on
PEEK with a message to peek@computron.com or visit
www.computron.com

Good luck!
