Note that for the Conn_Names option, the default value is different for RTgms than it is for an RTserver. The pgm prefix results in RTgms using the PGM link driver. For example, in UNIX, the PGM link driver creates a server-side connection on TCP/IP, port 5104 on _node and also on local, port 5104 on _node. RTgms sends data out either on a multicast address (if the number of receivers meets the value set in the Group_Threshold option) or on the TCP/IP or local connection of the client.
