:) What about this something like this in the config file for a part:
:)
:) ...
:) serial = yes | no;
:) parallel = yes | no | nohiv;
:) ...
:)
:) The result of setting these would be to set some single bit flags that

:) values to the stk500.
I think that is more complicated than it needs to be. If a device
doesn't support serial programming, then set parallel = yes, otherwise
default to serial.
:) parallel = yes | no | nohiv;
This doesn't make sense. hiv is not an option when parallel
programming since you _must_ take reset to 12V in order for the device
to switch into parallel programming mode.
:)
:) Is it the case that _all_ devices support serial so maybe including
:) that would be redundent.
Some of the older parts (e.g. at90s8534, I believe) don't allow serial
programming. If you want to support all devices, it's not reduntant.
