We run the BBN/Purdue IP/TCP under 4.1bsd on a Vax-11/780 talking to an LHDH, 
talking to an ECU, talking
to a 56kb DDS link to another ECU at a far away IMP.  Our IMP sponsor 
says they will have trouble supporting our connection since there are 
no diagnostic routines running on Vaxes for the ECU's.  ACC (the
ECU manufacturer) gives the same story.  We have no spare
PDP-11's around to try things out on.  My questions are:
has anyone else run into this lack of diagnostic routines and
what did you do about it?  Has anyone else heard of the version
of RT-11 which runs on Vaxes in emulation mode, (if so, where can
I get it?) and since there is ECU diagnostic software which runs under 
RT-11, would this be a possibility for getting around the
problem?  Thanks in advance.
