I have just done a simple test All 2313 port B set to output. do Portb=FF delay 5 seconds Portb=00 delay 5 seconds loop programmed with serial method (AVRPROG) connected a led to 5v rail and tapped the cathode to each portb pin in turn - all worked as they should - with or without the programmer left connected. regards, George Smith
