A while back I designed a PIC based TX system based around GPS and EasyRadio

One of the draw backs was that the GPS I was using required me to have a MAX232 chip to make the GPS into USART compatible data 

I was looking at Scott's GPS GPS GT-320FW - Would that be USART compatible ?

In that the idle is active high 5 volts, and then goes to zero.

Where as RS232 is -7 volts idle and + 7 volts
