Some development boards use the RTS and DTR lines to effect reset and 
ISP modes. Make sure that your serial set-up is not driving these in 
a way that will force a reset.

One simple way to do this is to make a simple D9->D9 cable that only 
passes through RX, TX and GND for use while testing the code.
