Rig control not working with Yaesu FT-747GX and DigiRig Mobile

[Smiles79]

I've got CubicSDR running on DragonOS, trying to use it as a panadapter with my RTL-SDR V3 and my Yaesu FT-747GX. I've got the SDR side of things working but I cannot get rig control working on my HF radio. I have selected "control rig," "follow rig," "floating center," and "track modem." I have selected my radio from the list, 4800 baud, and the control port is selected as "/dev/ttyUSB0."

These settings allow for rig control through WSJT-X and JS8Call.
