PC Software

The PC software used is PC Remote Control.  As it does not require the use of the RX line on the USART.  

It is better for experimentation as it lets you generate TX data only and it does not check whether the microcontroller is active by querying the microcontroller (generating data to the Rx port of the microcontroller) i.e. you only have to generate TX data and not worry about RX data so it's  easier.  Some control programs won't proceed unless the microcontroller gives the correct response.
