That's normal. Single-byte write operations did only work on old AVRs
where the flash write was not paged. If someone is seriously
interested, terminal mode could probably be rewritten to cache
single-byte writes, and coerce them into a page update, but I'd
consider that fairly low priority.
If you use the -U option (just -U flashfile is OK, the full form were
-U flash:w:flashfile:format), it causes avrdude to use paged write
operations which is supposed to work.

Never trust an operating system you don't have sources for. ;-)
