The Question is: Dear Wizard, the DECServer 200 connected to our old LN03-printer has just died. Now I am trying to connect the printer to the port of another DECServer 200. Could you please tell me how I have to configure this port? Unfortunately I can't ask the old server, it doesn't say a word ... Regards Martin The Answer is :
The configuration usually entails enabling the port for access remote and
queued, and with a line setting that matches the expectations of the
printer -- matching baud rate, character size, parity, and similar.
To this end, enable privileged access on the current terminal server port
via the "SET PRIVILEGE password" command.
Use SHOW SERVER to display the current server information, and use DEFINE
and SET to set the SERVER NAME to match your requirements.
Now use SHOW PORT to examine the specific port, the port the printer is
hooked to. The PORT name can be changed, but often simply leaving it as
the default PORT_n value makes it easier to associate with the specific
physical port used.
The terminal server port should not have the AUTOBAUD, AUTOCONNECT or
AUTOPROMPT characteristics enabled. Preferred service should be NONE.
The following commands will usually enable remote access to the port:
SET/DEFINE PORT x ACCESS REMOTE
SET/DEFINE PORT x Characteristic DISABLED
The OpenVMS Wizard generally recommends that all enabled
characteristics be disabled, save for INPUT FLOW CONTROL
and OUTPUT FLOW CONTROL. On a DECserver 300, only the
OUTPUT FLOW CONTROL setting should be enabled.
SET/DEFINE PORT x QUEUE ENABLED
This option is intended for environments with more than
one LTA0: device (on the same or on multiple systems)
sharing the same terminal server port.
SET/DEFINE PORT x SPEED nnnn PARITY pppp CHARACTER SIZE s
SET/DEFINE PORT x PREFERRED NONE DEDICATED NONE
SAVE PORT x
On the DECSERVER 500/550 only.
LOGOUT PORT x
SHOW PORT x
If you have more than one host LTAu: device -- either on the same node
or on multiple nodes -- ensure that the port is set for queued access.
Ensure that the SERVICE GROUPS settings match those of the host system(s)
involved in the connection.
You can often use TEST PORT x to trigger a test between the DECserver and
the device connected to the serial line -- this can help localize the
problem to the connection between the host and the DECserver, and the
connection between the DECserver and the printer.
In the various commands, some DECserver terminal servers will use DEFINE,
while others will use SET. Check the HELP text for the current DECserver
device for specifics.
Further, ensure that the broadcast characteristic is disabled both on the
DECserver port and on all LTAu: host terminal devices that are associated
with the particular DECserver port.
When working with print queues, the OpenVMS LATSYM print symbiont is the
most common and usually most appropriate queue processor -- PRTSMB will
work, but will tend to monopolize connections to the printer, and this
behaviour may be incompatible with sharing the printer among multiple
LTA0: device targets (on the local node, or on multiple nodes).
