Upon further investigation with the m700pro, I noticed that when trying a clone read using the remote jack, I get clone error in the ex2100 program, but the radio
has in fact received the clone request and is sending the data, but only on the clone port. Same thing happens when doing a clone write. The radio is in clone mode waiting for data but the data has to be received over the clone port, not the remote jack. Still haven't checked the m802.
BTW, if you have some soldering skills, the required clone cable/circuit is easy to make with just a few parts
