[bug #42324] Feature Request: Refactor rts/dtr toggling as generic option

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.

Thanks!

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.

This seems to be a nice feature if it can be done.

Issue #1262 is more or less the same as this one.

I will close this one and further discussion can be done in #1262.
