[Ham-Mac] Mac mini serial conntction to TNC

[Bob]

I have a Mac Mini and have been trying to operate my PC-9612. I connect 
it with a usb 2.0 to serial adapter and downloaded and installed the Mac 
drivers for it.  I have tried running MacTNC and Zterm but have not been 
able to define or find a serial port.

When go to modem preferences the only options I get is 
Bluetooth-PDA-Sync and Bluetooth-modem. If I use bluetooth modem, I get 
a message Error: 16 while trying to open selected port.
