(More complicated possibilities abound, such as putting another custom circuit in the line that sends the @ character before the RC has a chance to foul up the baud rate.)

I've tried for some time to get it to work without baud rate detection, but it's running at an unknown system clock rate, which makes it really hard to fix the baud rate to something like 115200. :)

I was able to fix it by adding a delay of about 1 second, however. Thanks!

Re: why does it say"IFI>"?

I believe that the Controller outputs this to indicate it is running (yes I know someone already said that) and that the microprocessor has initialized. (the printf statement is just to say that that part of the code had run...)
On the controller I am using, it shows up on every reset, although not for "programming mode". I believe that it is also meant to indicate to the IFI loader something, because the loader needs the code to be stopped, and program mode allows direct access to the memory?:confused:

I would think that a custom Loader program could explain this, but seeing as there is none around that anybody has had a need to make, I have no further information.

When you press and hold the Prog button it diplays IFI> in the console.
