Defines the mapping between a communication controller device and
    its corresponding Internet interface. Each mapping or controller
    definition is stored as a record in the configuration database.
    To modify an existing controller definition, you must delete the
    old controller definition from the configuration database (using
    the DELETE COMMUNICATION_CONTROLLER command) and then define
    the new controller definition (using the DEFINE COMMUNICATION_
    CONTROLLER command).
    Internet devices are uniquely identified using 2-character names.
    The first character is determined by the /INTERNET_INTERFACE
    qualifier. The second character is determined by the controller
    type you specify with the /TYPE qualifier, as follows:
    Controller
    Type             Second Character of Interface Name
    ETHERNET         E
    FDDI             F
    PPP              P
    SERIAL           L
    TOKEN_RING       T
    For example, with the following command, the communication
    controller EW maps to the interface WE:
    TCPIP> DEFINE COMMUNICATION_CONTROLLER EW -
    _TCPIP> /INTERNET_INTERFACE=W /TYPE=ETHERNET
    Related commands: LIST COMMUNICATION_CONTROLLER,
    DELETE COMMUNICATION_CONTROLLER, all INTERFACE commands

                                       [ /DESCRIPTION=text ]
                                       /INTERNET_INTERFACE=character
                                       /TYPE=(option[,...])
