Micrtochip AN1310 for USART2

[cerr99]

Hi There,

I've been unlicky trying to modify Microchip's AN1310 bootloader to be used with USART2 instead of USART1. Did anyone suceed porting thatcode over to be used with USART2?
I have changed all the registers that referred to USART1 to USART2 I believe but still can't get it working.
Help would be appreciated!

Thank you very much!
Ron

Changed the DigitalInput macro in preprocess.inc to clean up with the analog input issues on my 18f86k22:

DigitalInput macro
#ifdef __18F86K22
    #if BOOTLOADER_ADDRESS == 0
    nop                         ; start up GOTO instruction errata
    #endif
	bcf	ANCON2,	ANSEL18
	bcf	ANCON2,	ANSEL19
#endif

But that didn't get it going yet either...
