I think your solution is the correct one: use the buffer signal. This
one is supposed to be active all the time while AVRDUDE has the ISP
connection open.

The program LED is really only meant to be active while AVRDUDE is
writing to the AVR. Changing its meaning now might alarm other users
who are used to the current behaviour, making them believe they might
change something in their AVR inadvertently when they are actually
only reading.

We have a mux controlled by the pgm_led signal that disconnects the ISP port when not used (pgm_led high). For programming we are using the PONY-STK200 programmer connected to an ATmega128.

avrdude 5.1 does not set the pgm_led to ON during initialize (bitbang_initialize), resulting in that the AVR is not detected.

The current solution is to change the avrdude.conf file to control the pgm_led as if it were the buff signal. A better solution would be to always set the pgm_led ON when accessing the AVR (as PonyProg does?).
