Something magical would be needed > to additionally connect CASS WRITE. You could do it like the hands free kits where the answer buttons use in band signalling. So something like hookup cass write to the mic input when the motor is running & have some signal level that is used to tell the device that the motor is stopped. As long as the tablet can detect the difference between your motor stopped value and what is signalled on cass write during playback or recording, then you're done. You may be able to do cass sense in a similar way, rather than dedicating one ear to cass read and the other to cass sense.Received on 2019-01-18 15:00:03
