Thank mister e for the MultiCalc, I use it often.

Play with the above to get started with the USART. Notice they did not use DEFINES.

The program will echo your keyboard with one PIC connected to a PC. The terminal program that is part of MCS is good for this setup. I think the above sample is for 4Mhz. So check the values with MultiCalc.

Keep us posted...
