Detailed Description

Simple Point To Point Channel.

This class represents a very simple point to point channel. Think full duplex RS-232 or RS-422 with null modem and no handshaking. There is no multi-drop capability on this channel – there can be a maximum of two point-to-point net devices connected.

There are two "wires" in the channel. The first device connected gets the [0] wire to transmit on. The second device gets the [1] wire. There is a state (IDLE, TRANSMITTING) associated with each wire.
