'$' no longer causes bus pirate to reset to bootloader about dangerous-prototypes-open-hardware HOT 4 OPEN

I traced this back to revision r1955. In that revision, the "wait for TX done" 
line that is ran after $ is changed. It used to read:

    while (UART1TXRdy == 0); //wait untill TX finishes

But since that takes the address of the UART1TXRdy function (which is always 
non-zero) this comparison would always be false and this loop would never 
block. After r1955, the line reads:

    while (0 == UART1TXRdy()); //wait untill TX finishes

So now the function is actually called. I presume that for some reason that 
loop never finishes. Perhaps the TX never completes because it doesn't use 
interrupts on the BPv3 (that's just a guess, though).

In any case, if I comment out this while loop, the $ command works as expected 
again.

Cool, thanks :)

I think I found a solution for the issue:
Change 
while (0 == UART1TXRdy()); //wait untill TX finishes
To
while (U1STAbits.TRMT == 0); //wait untill TX finishes

This way we wait to empty the WHOLE TX buffer before jumping to the bootloader.
