Basic configuration of a DECserver 200/MC

Given: A VAXcluster with one VAXserver3600 and one VAXserver4100 running OpenVMS 7.1 and DEcnet-OSI 7.1. A DS200 (System Image PR0801ENG.SYS) which should send and recieve commands from a stored program controller - but doesn't right now...

When connected to that port via a terminal before the technical problem there I could see the command sent from the application and there was a answer from the SPC.

The first problem was, that the original DECserver had a broken logic board. Then I replaced it with another DECserver 200. The new DECserver boots the system image via MOP. I even setup the servers name and port settings I thought might work.

On the VMS side there is a LTA device, which I newly created, but now the application (Fortran77)still can't communicate with the SPC.

MCR LATCP
CREATE PORT LTA65: /NOLOG
SET PORT LTA65: /APPLICATION /NODE=DS200 /PORT=PORT_2
EXIT

SET TERMINAL LTA65: /NOECHO /SPEED=(1200,1200) /ANSI_CRT /NOEIGHT_BIT /PERM

Since the previous company in charge of that system didn't have a documentation I am kind of lost for a configuration that might work.

Is a basic configuration I have to setup so the DECserver should work in that kind of environment?

Adrian,

have you also set up the port on the DS200?

I have attached an example for a setup file for BDE devices we use, yours may look a little different.

Adrian,

if you manage your server manually you should consider using TSM software, shich is now freeware (you can find it via the HP Openvms site). It is for manageing LAT connected servers and allows for setup files, which can easily reset a server to known settings.

(My example above is from TSM).

Re: Basic configuration of a DECserver 200/MC

The setup on the DECserver I did:

DEFINE SERVER NAME DS200
DEFINE PORT 2 SPEED 1200
DEFINE PORT 2 PARITY NONE
DEFINE PORT 2 CHARACTER 7
DEFINE PORT 2 AUTHORIZED ALL ENABLED
DEFINE PORT 2 PREFERRED VAXCLUSTER

Local> sho port 2

Port 2: Server: DS200

Character Size: 7 Input Speed: 1200
Flow Control: XON Output Speed: 1200
Parity: None Modem Control: Disabled

Access: Dynamic Local Switch: None
Backwards Switch: None Name: PORT_2
Break: Local Session Limit: 4
Forwards Switch: None Type: Soft

Preferred Service: VAXCLUSTER

Authorized Groups: 0-255
(Current) Groups: 0-255

Enabled Characteristics:

Autobaud, Autoprompt, Broadcast, Input Flow Control, Loss Notification,
Message Codes, Output Flow Control, Verification


VAXCLUSTER = LAT Service Cluster Alias (It is shorter in real configuration. I replaced the original name since it is a classified system)

It would be usefull to me also if there is a way to talk to that LTA65: device from DCL somehow. That means can I set the SYS$OUTPUT to that LTA65: Device for testing?

It should be no problem to read/write from DCl to a LT port, we once drove digitizer tablets via a DCL routine.

When loading "moving message" displays connected to DECServers in the distant past, we were able to use COPY x.lis LTAnn: quite happily.

Re: Basic configuration of a DECserver 200/MC

How should I read/write to the LT Device?

ASSIGN LTA65: SYS$OUTPUT didn't work...

Re: Basic configuration of a DECserver 200/MC

$ open/read/write lun LTAxxx:
$ write lun ...
$ read lun ...

should work.

Try $ set host/dte lta65:

Everything you type will be directed to the SPC and
everything it responds with will appear on your terminal.

control-\ to exit back to DCL.
