Hi!

I have been playing with DECnet task-to-task communication between
DECnet-VAX and DECnet-Ultrix, and have run into a few problems. I
was wondering if anyone out there can set me on a straighter path.

Ultrix to VAX seems to work somewhat. Using the c function:
dnet_conn("vmsnod/user/passw","remfil p1 p2",0,0,0,0,0,0)
will open the file VMSNOD::REMFIL.COM in sys$login and pass the two
parameters. I am having some problems sending information across
to the VMS machine and back via SYS$NET and the Ultrix socket, but
I think this can be gotten around.

However, VAX to Ultrix won't work at all. The FORTRAN open statement

OPEN(UNIT=10,FILE='ULTNOD"user passw"::"TASK=remfil")
returns:

 %FOR-F-OPEFAI, open failure
   unit 10  file ULTNOD"user password"::"TASK=remfil"
   user PC 00000611
 -RMS-E-CRE, ACP file create failed
 -SYSTEM-F-NOSUCHOBJ, network object is unknown at remote node

and
OPEN(UNIT=10,FILE='ULTNOD"user passw"::"remfil")
returns:

 %FOR-F-OPEFAI, open failure
   unit 10  file ULTNOD"user password"::"remfil"
   user PC 00000611
 -RMS-F-SUPPORT, network operation not supported
 -FAL-F-RAT, record attributes field rejected

In other works, VMS TASK is not supported under Ultrix, and the Ultrix
default isn't supported under VMS. Is there any way to get around, under
or through this?

Ian.
