/DIAL=(NUMBER:number[,MODEM_TYPE:modem-type])
    Allows a modem attached to the outgoing terminal line to be
    autodialed using the autodial protocol of that modem.  The
    NUMBER keyword is the telephone number to be autodialed and
    is a required parameter.
    Before you can dial a new number, you must first log out of the
    current remote system.
    The MODEM_TYPE keyword is optional. It can be used to specify
    any of the following modem types:
    o  DF03 (default)
    o  DMCL (any modem that uses the DEC Command Language)
    o  DF112
    Each modem-type requires a specific modem dialer code.  Check
    with your system manager which modem dialer codes are installed
    in your system.
