Thanks for the response. We looked at using pexpect (I'm a UNIX guy at
heart), but we have variable command prompts, that may or may not show up,
with this program, so expect/pexpect would be difficult. John's suggestion
was to add some sort of unique ID as a good idea, but won't work in this
situation. I guess in the end, doing something with pexpect would be the way
to go if I needed to. This issue has been resolved in another way (per my
last message to the list).
Thanks again for the response,

This is a common problem. The Unix folks have traditionally used a
program called "Expect" to automate talking with interactive external
processes. There's a Python equivalent to Expect: take a look at the
'pexpect' module. Here you go:
The documentation on that page has a few examples that should help you get
started. Best of wishes to you!
