 Except that VM/Passthru won't talk to anything but another VM/Passthru
 via CTCA (or virtual CTCA).  I'd love to hear someone tell me otherwise,
 but as far as I can tell you are "trying to do the impossible".  The
 IBM response would seem to be: Just run VM/VTAM.  A suggestion that I
 find quite repulsive... :-)

 -jj

 BTW -- That's why we have our VM/SP and MVS/SP guest operating systems
 talking to each other over a bisync link that goes out one 3705 line
 set, into a modem eliminator, and into another 3705 line set!  In all
 fairness, the two 3705's used to be attached to different CPU's.  But
 now that MVS and VM both run on one CPU under VM/XA, I'd really like
 to do something more reasonable.  Which of course leaves out VM/VTAM. :-)
