Patch name: patch.increase-serial-timeout
Author: Bryce Denney <bryce@tlw.com>

Detailed description:
When programming an ATmega with self-programming, the erase command 
sometimes takes more than 1 second.  The serial timeout causes the 
operation to "fail" even though it's actually doing exactly the right
thing.  Increasing it to 2 makes it work on my system, but it presumably
depends on the clock speed of the target processor.  I suggest that we
increase the timeout to 5 to be safe.

If the timeout was increased just for the erase command, that would 
work too.
