[Omitted example showing interspersed echo and sleep commands piped
into ccr.]

I just tried the same thing on Ultrix 3.1, but with DECServer 2.0
software, and it works perfectly!  After messing around with it a bit,
I discovered that the sleeps aren't needed at all.  I have a file
with DECServer commands such as this:

ccr.commands:

access
mjb
show server
show sessions all
show users

(That's six lines total, including the first blank line used to get the
initial "#" prompt for the remote console.)

You can then issue the command "cat ccr.commands | ccr DSRV04", and it
will work perfectly.  Use of the pipe is the important thing, simple
input redirection, such as "ccr DSRV04 <ccr.commands" does *not* work,
as ccr will get "stuck".  Apparently ccr is doing some sort of ioctl()
which fails on a file, but not on a terminal or pipe.

Note that I also checked this on Ultrix 2.3, and it does *not* work.
The ccr program appears to want input from a terminal, and a terminal
only, under 2.3.

Anyway, since we're running Ultrix 3.1, it's a good solution for us.
Thank you, George, for the inital info leading to this!  It's going
to make our DECServer management a lot easier.  [And we won't even
have to buy VMS and that multi-million dollar Terminal Server
Management software! :-) ]
