Ok, I have MMTY receiving and think I have the COM port set correctly. I
don't have a 13 pin connector for ACC2 ( is there a source other than
Kenwood for those darn things??) so I tried PTT using the rig control. Rig
control seems ok and PTT will key but wont unkey. As I read the MMTY help
file the "\" in the buffer should unkey the rig. What did I miss?
