Bluetooth adds non-trivial latency though, as I recall. The KD protocol is (highly) latency sensitive. Even adding 10ms makes things significantly more painful.

Doron,
115K baud is a 115K regardless of how you connect it.
If he is talking about the BlueTooth cable replacements then they look just like a real serial port on both ends.
We use them and they are just as good as long cable.

Do us all a real favor if you can. Get a KB out for XP that fixes the firewire driver to work with VIA chipsets and or add USB to XP.
For the for see able future, the "rest of us" still have to debug with XP, and unless you have the magic firewire chipset, most of use use 115K serial links.

Ya, I know - I'm dreaming.

Jim

Why would even want to run over bluetooth? The debug speed would be abysmal. The target side (i.e. the machine being debugged) needs to see a UART at the hardware level, not the software/emulation level.

Interesting question; unfortunately, I don't know the answer. It seems like it should work as the target side would presumably see
a UART, lack of which is usually the deal breaker for WinDbg transport alternatives. Where you lose me is the part about needing
one on the host side, because it seems like you would have to, as WinDbg can't connect over Bluetooth, but I think that I'm missing
something.


Good luck,

mm
