The problem is that there are no "good" ways to connect IBM O.S.
to the outside world.  IBM is working on TCP/IP for VM and MVS but
the availability is 6 months to a year (I think).  IBM wants everyone
to talk SNA and the hardware/software from outside vendors isn't there
yet.  (DEC is getting fairly close according to Computerworld).

Oracle can run networked databases between UNIX boxes and UTS
(currently in Alpha using TCP/IP).  We should have MSDOS to
VM/MVS running this fall (using a 3270 interface I think).
I doubt there will be anything for UNIX to VM/MVS in the near future
(there isn't much market demand for it yet).

Gregory Minshal wrote a program called tn3270 which provides a TELNET
interface between IBM machines and UNIX machines.  It is found in
the user contributed software on our Pyramid and has a University
of California copyright.  It handles the mapping between the 3270 and
dumb terminals quite well.  It is heavily dependant on the BSD TELNET
interface.  (If anyone has adopted this to run on an EXCELAN telnet
interface (on VMS) I'd like to hear about it.)
