Thanks guys for the help, but I seem more confused than ever before about
this serial (UART) stuff now.

Would someone please be able to a have a quick look at my code (below), and
tell me (exactly) what I need to change to get it working? I realise this
maybe a large ask, but once I can get the serial stuff working I can start
using it to debug other stuff back to a computer screen.

All I need to do is send data through the uart to HyperTerminal on a
computer at 9600bps, using a 18F8720 chip and Htsoft PIC18 C compiler?

Could someone please help I am really desperate?

CODE:
#include <pic18.h>
#include <stdio.h>

#define BAUD_RATE 9600
#define CLOCK_FREQ 19660000
#define USARTGET (RCREG1)
#define DATA 1

static void usartput(unsigned char c);

static void usartput(unsigned char c)
{
while(!TRMT1)
TXREG1=c;
}

bit kbhit(void)
{
unsigned char b;
if(RCIF)
{
if(FERR1||OERR1)
{
b = RCREG1;
CREN1 = 0;
CREN1 = 1;
return(0);
}
else
return(1);
}
return(0);
}

void
main(void)
{
TRISC7 = 1;
SPBRG1 = (((CLOCK_FREQ/BAUD_RATE)/64)-1);

TXSTA1 = 0b00100000;
RCSTA1 = 0b10010000;

do
usartput('s');
while(DATA == 1);
}
