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.
