The CONNECT command, which may be abbreviated to "C",
instructs the router to make an outgoing (downlink) AX25 level
2 or 4 connection with another system.
If the target is a known node (i.e. one which is in the nodes
table) a port number is not required, and will be ignored if
supplied. The router will attempt to make a NetRom level 4
connection with the target, using information from the routing
tables. However, a level 2 connection with an immediately
adjacent node may be forced by using the target's alias with
an arbitrary SSID, specifying a port number if required (e.g.
C 4 MLVN-1)
If the target is not a known node, the router will attempt to
make a level 2 connection. On multi-port systems, a port
number must be specified.
The "V" (via) parameter allows up to 7 digipeaters to be
specified, e.g.: "C 3 G6YAK V G8NTU G8EPR"
The "S" (stay) parameter, e.g. "C <nodecall> S" causes the
uplink session to stay connected when the downlink session to
the target node is terminated.
