/* PIC 18 Software UART library header

 * The I/O pins must be specified for the software UART. The
 * corresponding TRIS bits must also be specified. The notation is:
 *     PORTx,y  where x is A,B,C etc. and y is the bit 0-7
 *     TRISx,y  where x is A,B,C etc. and y is the bit 0-7
 * This is in assembly language notation because assembly is
 * used to initialize the software UART.
