Writing telnet scripts using the Unix telnet command can be tricky and
unreliable.

You need to remember that as soon as the Unix side tries to send something to
the 3000 side, it gets transmitted whether or not the 3000 (or any other
machine) is ready for it.  So if the remote end isn't doing typeahead
buffering, you have problems.

The solution is sort of a kludge, but I've done this for certain simple
applications:

(sleep 3; echo "hello manager.sys"; sleep 3; echo "passwd"; sleep 3; echo
"command"; sleep 3; echo "bye"; sleep 3) | telnet lx8

The concept here is that you need to build in sufficient pauses between the
data you're trying to send so that the remote side will be ready to receive the
next chunk.
