CHAPTER 4: Host Configuration
$ RUN SYS$SYSTEM:LATCP
LCP> CREATE PORT LTAnnnn/APPLICATION
LCP> SET PORT LTAnnnn/node=nodename/port
=portname
LCP> SHOW PORT LTAnnnn
LCP> EXIT
Above, nodename is the name of the EPS (EPS_xxxxxx) and portname is the
name of the EPS print port to use (Port_1 is the serial port, Port_2 is the
parallel port). The SET PORT command actually maps the LAT port to a
service connection on the EPS, so that data sent to this port will be
transparently forwarded to the EPS. You do not use the service names
(EPS_xxxxxx_S1, etc.) in this example.
LAT is disabled by default on the EPS services out of network traffic
considerations—active services result in LAT multicasts. If you do enable LAT
on the EPS services, you can then use the EPS’s service names instead of the
port name. For example
LCP> SET PORT LTA1278/node=EPS_00452a/port=Port_1
can also be set up as
LCP> SET PORT
LTA1278/node=EPS_00452a/service=EPS_00452a_S1
because Port_1 is the name of the port that service EPS_xxxxxx_S1 (the serial
port service) refers to. This method can also be used to reference Port_2, the
parallel port. If you change the port or service names on the EPS1, you will
need to modify the LATCP SET PORT command to reflect the new names.
Also, LATCP ports are not permanent on the host, so you will need to
configure them after every reboot or add the configuration to the host’s
startup file.
For example, if you want to create a new LAT device LTA1234 that accesses
print service EPS_043ea1_P1 on the EPS1 named EPS_043ea1 using VMS
queue EPS_PARALLEL enter the following commands:
$ RUN SYS$SYSTEM:LATCP
LCP> CREATE PORT LTA1234/APPLICATION
LCP> SET PORT LTA1234/NODE=EPS_00452a/SERV=EPS_00452a_P1
LCP> EXIT
Then start the VMS queue with the command:
$ INIT/QUEUE/START/ON=LTA1234:/PROCESS=LATSYM
EPS_PARALLEL
