The Question is:
VMS Version 4.5 DEC Vax 630 Q5
I have a VAX/VMS 4.5 Microvax II with 16 serial ports on the back plane. I want
to use one of the serial ports to communicate with an NT server running server
version 4.0 or 5.0 (latest). I thought about TCP/IP, DECnet and serial line
nication methods. The best I think would be to use Async Decnet between the PC
and the MicroVax. I am looking for suggestions on the PC side, on what product
to use for establishing DECnet on Windows NT. I also would like to know what
components are neede
d on the MicroVax to establish the DECnet link with Windows NT. Alternative
suggestions are welcome.
The Answer is :
Acquire a DELQA Ethernet controller -- point-to-point serial connections
are not usually worth the time and effort, particularly if the systems
involved are located within the supported diameter of an Ethernet network.
A DEQNA Ethernet controller is another alternative given the vintage of
this system, but the DELQA is the prefered controller and the DEQNA itself
is not supported starting in the V5.4 and the V5.5 releases of OpenVMS VAX.
There is a DECnet stack for Windows NT available as part of the PATHWORKS
Client product, though the OpenVMS Wizard would typically recommend the
use of IP on both hosts.
It might also be simpler and easier (and faster) to replace the circa 1986
MicroVAX II with a more recent VAX system or to OpenVMS Alpha -- the
MicroVAX II is the slowest VAX still supported by OpenVMS VAX.
The OpenVMS Wizard will assume that you are aware that an operating system
release as old as MicroVMS V4.5 (released in 1986) will require an uprade
to something rather more current (eg: V5.5 or V7.2), as acquisition of
layered product software (such as a TCP/IP stack) will be quite difficult.
The OpenVMS Wizard is not in a position to recommend PC products.
