I built an AVR910 compatible programmer but had trouble getting it to work.  When attempting to program flash, AVRDude indicated that the programmer failed to repsond to an LED command.

According to the the table in avr910.asm from Atmel, the x and y commands are to be accompanied by a data byte.  The firmware in my programmer was waiting for that byte but it is apparently not being sent by AVRDude.  After I commented out the call to read the extra byte in my programmer's firmware everything started working.

So, the question is: should AVRdude be sending an extra byte after the x and y commands before waiting for the programmer's response?
