121 hardware DCD, par96 implies software DCD).
127 Hardware DCD versus Software DCD
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.
143 a reasonable DCD algorithm in software. Therefore, if your radio
144 feeds the DCD input of the PAR96 modem, the use of the hardware
145 DCD circuitry is recommended.
