I am having an I/O communication issue with DXL Commander, N1MM+ etc. Cable is not issue. Connection is over Com 8 using FTDI driver. PC says COM8 is working OK.
Here are the symptoms:
1. K3s / Commander Commander is receiving VFO A data but not mode. I must enter mode manually into Commander. Commander cannot control K3s. Commander does not read VFO B. I have tried several baud rates and polling rates.
2. N1MM+ cannot discover radio at all.
Hard to imagine K3 I/O board failed. Has anyone experienced that? If it were Windows port failure, OS would tell me port failed.
In short I am totally stumped
