There is some problem with USB serial!
I have Arduino IDE v1.6.5 and trying to convert my micro to ArduinoISP with sketch from examples. It compiles well but isn't work with avrdude!
$ avrdude -C c:/temp/avrdude.conf -patmega328p -b19200 -cavrisp -Pcom22 -U flash:r:test.hex -v -v
avrdude.exe: Version 6.0.1, compiled on Apr 15 2015 at 19:59:58

System wide configuration file is "c:/temp/avrdude.conf"
Using Port : com22
Using Programmer : avrisp
Overriding Baud Rate : 19200
avrdude.exe: ser_recv(): programmer is not responding
avrdude.exe: stk500_recv(): programmer is not responding
avrdude.exe: stk500_getsync() attempt 1 of 10: not in sync: resp=0x03
I cheked it with PuTTy and "Serial Monitor" by sending "1 "(one and space). It respond with "AVR ISP" and this looks nice but then I tried to do the same using HTerm and it gave no reply!
I checked what happened with SysInternals PortMon and discovered that neither HTerm nor avrdude sets SERIAL_DTR_CONTROL. So I downloaded source of avrdude:
$ svn co svn://svn.savannah.nongnu.org/avrdude/trunk
and changed line in avrdude/trunk/ser_win32.c:
-dcb.fDtrControl = DTR_CONTROL_DISABLE;
+dcb.fDtrControl = DTR_CONTROL_ENABLE;
recompiled and it works like a charm!
No public wish lists :(
