In a future revision, I wonder could the XBEE -RESET be activated from a processor port.
The XBEE skt supports a number of pluggable modules, some of them are very sophisticated. Sometimes these modules become unresponsive, in an ideal world maybe you could figure out what set of commands resulted in their demise.
A practical way is to apply a reset to the module and then it should behave determinstically. Of course if the module power supply can be greated then that of the processor it may need to be decoupled with an Open Collector FET arrangement.
Some processors support a - RESET pulse coming from the processor reset line if there is an internal reset, but I couldn't see this on the mega1284.
