Paul, Roger, et al,

While you are thinking about getting a PCB put together, please try and include an RS232 DB9 connector and MAX232 chip to connect to the Tx Rx of the atmega16.
This will be VERY useful for both the 144volt controller and Rogers air conditioning motor controller.

Here is a site that shows the very schematic and........tadah!.......source code to use for input and output. Have a look. It is very simple and straight forward, right up our alley!
