mega 2560 does not work as an ISP about mega-isp HOT 3 OPEN

[deleted comment]

I have now fixed this problem with a change to avrdude and a change to mega-isp 
- the correct patch is detailed below.  The idea is to flush the receive queue 
in ArduinoISP so that case '0' - signon does not respond to multiple signon 
attempts from avrdude it only responds to one signon attempt.  Without this fix 
ArduinoISP is not in sync with avrdude because it sends multiple signon 
responses and the second and third signon response are incorrectly interpreted 
as responses to subsequent avrdude messages.  The fix in avrdude is included 
fyi so that you can test this change.

Note I have also created a bug in the avrdude project for this issue see
