Michael,
It depends on what type of software you are running on the PC.
If you are talking directly to the serial port (or USB port) on the
PC side, then you don't need to adhere to any specific packet
type, you can invent your own (if that's what you want to do).
Or, you can use the RCX or LNP packet formats. It's up to you.
Perhaps you can describe what the PC side will be doing so
it would be easier to give a more specific response.
