/TRANSPORTS="transport-string"

    Specifies the transports that this proxy server monitors for
    incoming client requests. If the /PARTIAL qualifier is not
    used, all transports specified by this qualifier must initialize
    successfully; or the proxy server fails to initialize with the
    server number in use, and the next server number is tried (as
    discussed in the description of the /SERVER qualifier).

    The default is /TRANSPORTS="LOCAL,DECNET,TCPIP".
