[Xastir] Trouble with my KAM+

[Eric Christensen]

Well, just for kicks I put the KAM+ in KISS mode and tried to configure 
Xastir to do a multi-port KISS TNC.  Now it transmits on the VHF side 
but not the HF side!  I have changed the "radio port" number from 0 to 1 
to 2 but haven't been able to get it to switch from the VHF side to the 
HF side.  Anyone have any ideas about this one?
