You did what?!?! Wow, didn't expect that this works.
Thanks for the info.

But now you spoiled your dongle and lost guarantee, hehehehe...

Nah, seriously. I'll publish our dongle firmware, which
is completely in assembler. I'm just a little bit scared,
because dongle problems are reported most often by people
who bought Starter Kits. Since their first release, we
never changed the firmware, if I remember correctly.
What would happen, if modified releases are floating

Btw. there is a serious problem with it. Our dongle will
not work with targets running on 8 MHz or below. Jan Rehak
reported this recently and we also failed to program older
systems with 3.6864 MHz crystals. Jan plans to design a
newer version using an AVR with more RAM.

>Which version of dongle firmware are you using ?

uisp version 20030827cvs
