I run into this problem when I mess something up, and it's pretty annoying to wait for 10 not in sync timeouts before I can try some different method.
...
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x85
How can I set the number of "attempts" to say 2 instead of 10? Or how can I safely interrupt the upload process in the IDE?
