Obtains access to the host remote console of a workstation.
Description |
 |
This command obtains access to the host console of a workstation. While
you have access to the console, the console mode prompt that you have
configured for the workstation is displayed on the screen in place of
the usual NRJE prompt. (The console mode prompt is configured in the
NRJE Configuration: Workstation Data screen.)
The following conditions are necessary for this command to
be issued successfully:
You must have NM capability, or if
you do not have NM capability, this command must have been "allowed" on
the NRJE Configuration: Workstation Data screen.
The communications line for your workstation must
be open; the workstation must be connected to the host job entry
subsystem.
The console facility must be free or available.
Up to 28 users can access the console simultaneously.
Note that since you cannot specify a Wsid in this command, you can obtain access to the console
of the default workstation only.
Once you can access the console, you can enter host console
commands. Each of these commands must begin with the configured
host command prefix character configured on the NRJE Configuration:
Workstation Data screen. For example,
where CONS> is the console mode prompt configured for the workstation,
and $DA is a JES2 host command. (The $ is the host command prefix character.)
While you have access to the console, you receive all console
messages issued by the host. So, you can receive console messages
in response to your own commands, as well as messages in response
to commands by other users. You also receive all other output sent
by the host to the remote console. This includes host "Job
Received" messages sent by some host systems when a job
is received from a remote workstation. NRJE writes this output to
your job or session output device, $STDLIST.
Node Management Services can also log messages (CLAS0013 in SUB0002)
sent to the host remote console of your workstation. If no user
has access to the console, you can retrieve a lost message by using the
Node Management Services utility program NMDUMP. See the SNA
Link Services Reference Manual (for MPE V) or Using
the Node Management Services Utilities (for MPE XL)
for more information about this utility.
If you currently have access to the console and no longer
need it, issue a RELEASE command. That command terminates your access to the console
and frees that facility for use by other users.

Programmatic access to the host remote console is provided
by these manager intrinsics:
NRJEConsole: obtains access to the console.
NRJESendCmd: transmits a console command.
NRJEConsCheck: determines whether any outstanding host remote console
messages are waiting to be received.
NRJERcvMsg: receives a console message.
NRJERelease: relinquishes access to the console.
These intrinsics are described in the SNA NRJE
User/Programmer Reference Manual.
