Here's something I saw about this:

I'd like to add this as a macro.

What type of peripherals are available on the MISO pin?

Ian; I have developed an automatic baud rate detection macro for the BP. 
Attached is a .hex file with the new UART macro. Also includes the 1wire 
library I created for BP. test it out; if you like it I will hand the source 
over to you.

Forgot to mention; it outputs the actual calculated baud rate (using a 32bit 
timer; much like the getfreq function in auxpin.c. and it also outputs the 
'nearest common baud rate' like:

Actual Baud Rate: 9683
Nearest common baud: 9600

its pretty sweet. Cannot measure above 16000000bps because the BP speed. but 
thats the the hiest end of baud anyhow so it shouldnt be an issue. I just have 
the function tell the user; baud to high must use a logic analyzer or somthing 
of that nature.
