Agreed. I've already fixed it in cvs. [-dparallel -> -dhiv].

I have no idea what's going on there since that was added before I
showed up. It seems to be some kind of parallel port type programmer,
which is confusing, since I thought Atmel's AVRISP was a serial
programmer compatible with stk500. Was there some Atmel appnote that
talked about this type of programmer? [Just looked and didn't see
one]. I'll change it, but I don't know what to change it too. ;-)

Known problem. From the TODO file:

 - The handling of fuse and lock bits needs some serious work. As it
   stands it does not work with Hi-V parallel programming (on stk500).
   I've started working on this, but it was way too intusive a change
   to do just before a release. [TRoth/2003-05-27]

uisp is not too high in my work queue right now. I have a huge partial
patch for the hi-v/fuse stuff, but haven't worked on it for a while.

Would not surprise me if old firmware was buggy WRT to the tiny11. I
don't have a tiny11 for testing; do have some tiny15's although I'm
haven't used them yet and don't know what the diffs are.

I'm always willing to accept test samples as donations... ;-)

I have no idea. You're the first I've heard from.
