>Does anyone have experience getting "Dialup Dynamic Asynchronous DECnet" to >work? I am trying to get a MicroVAX (VMS V4.2) to communicate with an 11/780 >(VMS V4.2) by this method with no success.

There is a known problem with Asynch DECnet in VMS 4.2, which is fixed in 4.3, so you should at least upgrade to 4.3 before trying again. The problem would cause the 780 to crash in NETACP, with NO STATE TRANSITION (not exact words) bug. I was told at Dallas DECUS that it was because that the uVAX-II is too fast for the 780, and some timing logic caused the NETACP to go into an impossible (supposedly) state. -- Portia Bjorndahl UUCP -- {allegra|ihnp4}!scgvaxd!engvax!portia Hughes Aircraft Co.
