/DEVICE_SPECIFIC=(FUNCTION="xxxx",VALUE=(n1,n2,n3...n16))
       /NODEVICE_SPECIFIC

    Allows some device-specific parameters to be adjusted. These
    are useful for debug purposes or for experiments while doing
    performance measurements. Like other LANCP commands which affect
    devices, this command requires SYSPRV privilege.

    Specify the negated qualifer to clear all device-specific
    parameter data.

    These functions are described in a text file on the system,
    SYS$HELP:LAN_COUNTERS_AND_FUNCTIONS.TXT.
