I did come across a Perl script that seems to do what I want for the
time being after a couple variable modifications:

We tried the 'cat /dev/ttyS?' route on a SCO box, but it would time out
every so often. Besides, we're ditching all SCO since The Debacle and
want a more graceful solution on Linux.

Well, I don't know much about telephony, but I do know it is an SMDI
stream simply because that's what is labeled on the cable :-)

Thank you for your suggestions and pointing me in the right direction!
