ABSTRACT:
In a modem that transmits signals to and receives signals from a remote device at a multiplicity of communication rates, the quality of the channel is monitored, a communication rate is selected based on the channel quality, the desire for an increased rate is indicated, and the increased rate is implemented by the modem when the remote device concurs.
