Format:	START TRANSPORT /GROUP=n

 Grouping is a method for segmenting LANs such that services associated with
 certain nodes will not be by seen by other nodes.  An example of such an
 environment would be an extended LAN.  Here, a network manager may wish
 to restrict nodes to services offered on their own LAN segment.

 When specifying a group, the user should enter a number between 0 and 1023
 inclusive.  The default group is group zero.
