       /DEVICE=device-name

    Specifies the LAN controller device name for a LAT data link (for
    example, XEB0:). Only one LAT data link can be associated with a
    LAN controller. If you enter the CREATE LINK command without the
    /DEVICE qualifier, LATCP attempts to find an available controller
    by using a list of possible LAT data link device names. Digital
    advises that you specify a default device name by defining the
    LAT$DEVICE logical name.
