take a look at this code (this is just the main part)

void main()
{
serial_init(); //initialises the serial port
for(;;)
{
sendCharacter("TEST");
DELAY();
}
}
it works perfectly through the direct to Com 1 port on the UART screen in my compiler without the DELAY(). Once the DELAY is introduced it just seems to freeze. I have tried everything. I am quite new to this area but I need to finish this as part of a college project. I REALLY need some help, I have tried everything. is there anyone I could e-mail for help?
