1    /ECHO

       /ECHO
       /NOECHO (default)

    Enables partial tracing of received and transmitted downline
    load messages (the first 32 bytes of the data portion of
    each message). Note that the last one or two MOP messages
    are displayed in full: the memory load message with cluster
    parameters, and the parameter load with transfer address message,
    where present in the load.

    The data is written to a log file SYS$MANAGER:LAN$node-name.LOG.

    To obtain the entire contents of each message, use the /FULL
    qualifier as follows:

    SET ACP/ECHO/FULL

2    /FULL

       /FULL
       /NOFULL (default)

    When /ECHO is enabled, displays the entire contents of received
    and transmitted downline load messages.

3    /OPCOM

       /OPCOM (default)
       /NOOPCOM

    Enables OPCOM messages from LANACP LAN Server process.

    Messages are generated by the LANACP LAN Server process when
    a device status changes, load requests are received, and
    loads complete. These messages are displayed on the operator's
    console and included in the log file written by LANACP,
    SYS$MANAGER:LAN$ACP.LOG.

4    /STOP

    Stops the LANACP process. It can be restarted by reexecuting the
    SYS$STARTUP:LAN$STARTUP command file.
