//* Title: AVR068 - STK500 Communication Protocol
//* Filename: command.h
//* Version: 1.0
//* Last updated: 31.01.2005
//*
//* Support E-mail: avr@atmel.com
//*
//The communication between the STK500 and the PC is done over RS232
//(PC COM port). The STK500 uses: 115.2kbps, 8 data bits, 1stop bits,
// no parity. The PC should be set up similarly for the communication to work.
