It might be possible to hack up something using ckermit. Kermit has
a fairly powerful programming language, obtuse though it may be.
Check out the kermit web pages at http://www.columbia.edu/kermit/
for lots of documentation. I'd think you've probably already got
kermit on your box, or at least on the CDROMs, though I haven't
personally checked FCx for its presence, it is present on RHEL.
