Re: [avr-gcc-list] avrdude, read fuse bits?

File type `m' is an immediate value: the value is not taken from a
file but present on the command-line directly (in place of a file
name).  Obviously, this only makes sense for write (to the AVR)
operations, not for read operations.

All informational output is sent to fd 2 (stderr).  Drop stderr, and
use stdout for the output file:

$ avrdude -p m128 -c ponyser -P /dev/cuaa6 -U lfuse:r:-:r 2>/dev/null | hd
00000000  fe                                                |þ|
00000001

Not yet.  There's been the idea to have a combined fuse memory space,
but that hasn't been implemented by anyone so far.

avrdude -v (and no other parameters)
