IBM most certainly does have TCP/IP... at least for VM/CMS.  In fact,
they just announced a new version of it a month or two ago.  It uses a
DACU (Device Attachment Control Unit - a "7170", I think).  It seems
to understand subnets and the whole deal; Purdue has it running on
their 3083 and one of their 4341s.  I use "tn3270" to go from my Sun,
through about three gateways, and onto the 3083 regularly with no
problems.  If you're truly desperate, I could dig up the product
numbers and things for you, send me mail.

FTP seems to work quite well.  TELNET is there, but you have to run in
ECMODE (full-duplex instead of half-duplex).  TELNET'ing to a UNIX
system using a 3270 block-mode terminal is "interesting", to say the
least.  It's usally easier to log in on UNIX and use "tn3270" (makes
a serial terminal look like a 3278).
