Are you referring to the notorious D700 bug where it gets stuck in the 
"Opening TNC" state when the computer connection is lost while the 
D700 is reading a NMEA sentence from the GPS? 

If so, there is a way to clear that state without resetting the D700, and
a way to avoid causing it --- Xastir has had those commands in its startup 
and shutdown D700 configuration scripts for over two years, so it should be 
very rare now (as in, only when you have a computer crash or shut down without 
letting xastir go through its shutdown script, or you set it up to not use 
those scripts).

For an explanation, see:

I think this is a different problem than Robert and Andrew are describing 
(since Robert says that APRS mode works), but the D700 "Opening TNC" issue is 
easily fixed without resorting to a hard reset and losing all your programming.
