Hi,

If you have a look at RB7 it is also called TX. This is the HARDWARE port for the serial communication. HSEROUT or HSEROUT2 will be the tool for this :-)

When you use the hardware serial port you only need to put a byte in the transmit buffer and then the PIC will send out the 10 bits for you with proper timing (start bit, 8 data, stop bit) so the interupts will not trash your data.
