131 busy. This is the task of the DCD circuitry/software. The driver may either
132 utilise a software DCD algorithm (options=1) or use a DCD signal from
136 ser12 if software DCD is utilised, the radio's squelch should always be
137 open. It is highly recommended to use the software DCD algorithm,
