[avrdude-dev] [patch #7680] Fixing timeout problem in ser_recv in ser_win32.c

[Rene Liebscher]

Follow-up Comment #1, patch #7680 (project avrdude):

Some measurements when using the bus pirate without a connected mcu (so it
fails to initialize it and returns with error, but to do this it already send
several commands to the bus pirate.)

* original code:
** binary mode :        *0m20.329s*
** ascii mode :         *4m11.766s*

* patched code:
** binary mode :        *0m1.156s*
** ascii mode :         *0m3.547s*


Command line for binary mode:

$ time ../avrdude -c buspirate -p m8 -P com7

Detecting BusPirate...

**  Bus Pirate v3b
**  Firmware v5.10 (r559)  Bootloader v4.4
**  DEVID:0x044F REVID:0x3043 (24FJ64GA002 B5)

BusPirate: using BINARY mode
avrdude.exe: initialization failed, rc=-2
             Double check connections and try again, or use -F to override
             this check.


avrdude.exe done.  Thank you.
