What's the chance once you get this going,  of a spinoff device that 
would replace the TX/RX audio in/out of the T2 with a serial port?

I'm thinking of what would essentially be a protocol converter that 
could go inline between an existing D710/D700/TH-D7 or a KPC3 and the 
Nuvi, allowing the Nuvi to act as an intelligent terminal for existing 
TNCs.   I'm thinking that the existing board layout could be re-used 
with the on-board radio-interface DB9 connector re-purposed to be a 
RS-232 serial interface instead.     Or does the CPU only have one 
hardware serial port?
