120 busy. This is the task of the DCD circuitry/software. The driver may either
121 utilise a software DCD algorithm (options=1) or use a DCD signal from
124 ser12: if software DCD is utilised, the radio's squelch should always be
125 open. It is highly recommended to use the software DCD algorithm,
129 par96: the software DCD algorithm for this type of modem is rather poor.
