[OZAPRS] TNC Trace mode

[Colin Matten]

Hi Andrew, 

You need to bit shift each character to the left by 1. 
        
0x82 -> 10000010 -> 01000001 ->  0x41 = Ascii A 

Decoding the 7th Byte or SSID of the Destination, Originate and Path
nodes. 
// SSID Bitmap 
// 76543210 
// H         Has been Repeated 
//  R        Reserved, Set to 1 
//   R       Reserved, Set to 1 
//    SSID   SSID 
//        E  HDLC Extension bit 
//                0 more header to follow 
//                1 last byte of header 

   A  P  U  2  5  N  SSID
