I continued looking into this and found some stuff out. I still hold to
that I know almost nothing about SNA but heres what I think I learned
today.. In order for an IP host to talk to an SNA mainframe you need a
gateway and also some sort of software (like a 3270 emulator) on the IP host
to talk to the gateway. The gateway talks IP to the host and SNA to the
mainframe. The only way to do this without needing a gateway is if you use
a Cisco 7000 series router with a card called an ESCON card which can
function as a gateway. Heres a good link on what I learned. I'm still
reading it but I thought you might find it interesting. It basically talks
about how SNA is on its way out the door being replaced by IP and how a lot
of businesses are doing the migration in 4 steps.

Wow, thanks! I appreciate the compliment. As I mentioned, I'm not much of
an SNA guy, I know just enough to be hazardous. That one server I talked
about is the only time I've ever seen a Windows-type Intel-based server
speak SDLC. It's completely vendor-controlled, we just hooked it up to our
network and like any of our other SNA devices at they configured it.
Because of that, I have absolutely no idea what they have running under the
hood. I was basically handed a serial cable and they said "Connect this to
your router." :-) If I run across some info on it, though, I'll pass it
along.
