UDP to the Remote. Upon receiving the packet, the Remote strips the
data out of the UDP packet and sends it out its
COM port. Likewise, data
presented at the Remote’s
COM port is packetized, sent to the Access
Point, stripped, and sent out the Access Point’s
COM port. Note, this
configuration does not use multicast addressing.

Note that in this example, the TCP mode does not involve the Access
Point. Thus, the transceiver in a single network can run in both modes at
the same time. In other words, some Remotes can be configured for TCP

1. Either COM port can be used, but they must be the same ones at both ends
of the link. Both COM ports can be used simultaneously for two independent
data channels.
