This should be good for non-Windows platform. I will check on Windows platform later.

avrdude_pr1555 error: unable to open port com1 for programmer urclock
Possible candidate serial ports are:
  -P COM4 (via ch340 serial adapter)
  -P COM9 (via ch340 serial adapter)
Note that above ports might not be connected to a target board or an AVR programmer.
Also note there may be other direct serial ports not listed above.

avrdude_pr1555 done.  Thank you.

I wonder whether it makes sense to handle the -C option in a way that it defines the sole config file(s) to use – rather than invent another option.

Oh, and since that's a change that breaks backwards compatibility (even though in a way that nobody might notice), it would be a reason to bump the major version number. ;-)

handle the -C option in a way that it defines the sole config file(s)

Only just now saw this; AVRDUDE has a very elaborate configuration file processing: it allows to redefine the system-wide one, it allows a personal one, and it allows additional config files to be processed after the system one and personal ones using -C +.... I wouldn't want to change that mechanism as some users could rely on this.

rather than invent another option

We could parse -C no-rc to mean what -N does in this PR. Technically, this is incompatible with previous use but would only affect the user who likes to replace the system-wide config file with their own file called ./no-rc; I wouldn't bump the version number for that.

What is the preference here, -N or -C no-rc?

I would definitely prefer -N

Same here. I think this PR is good to go now.
