A.5. Many-to-One Specification

    # Here is an example of multiple sources going to a single destination.
    # It is also possible to cause a message from a single source to be sent
    # twice or more to the same destination (if the line "icp0port0 > icp6port3"
    # were repeated several times, for instance).
    #
    # icp0port0 > icp6port3
    # icp1port0 > icp6port3
    # icp2port0 > icp6port3
    
    #--------------------------------------------------------------------------#
    # The examples above illustrate switch specifications which the            #
    # Message Switch will perform autonomously, without any client             #
    # session connection; it simply switches packets between data streams.     #
    # Client sessions may be used simultaneously, as long as no client         #
    # sessions attempts to connect to a device and port which is already in    #
    # use by the Message Switch (for example, if the Message Switch is         #
    # connected to icp1port0, then no other client may use that device).       #
    #                                                                          #
