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,
141 par96 the software DCD algorithm for this type of modem is rather poor.
