I concur. This ought to be configurable in a similar way to the serbb programmer, with a reset and (why also not) a power statement that can be mapped individually to dtr and rts to allow either signal and either polarity to control the reset state.

Currently two different programmer types (arduino and wiring) each individually implement RTS/DTS toggling for automatic reset into a bootloader on a target board.

I'd like this to be a generic option that could be applied to any serial-based programmer, either as a command-line option or programmer config feature.

It would be useful for bootloaders like xboot (
http://alexforencich.com/wiki/en/xboot/start) which implement avr109 as a protocol. Currently I've patched butterfly.c to do auto-reset, but it seems more sensible to make it a generic feature.
