    Have you checked the PC port or the signal from the cable?

    I'm using COM1 to send/receive data to the PIC, and i'm also using COM1 to program the PIC (using only one program at a time of course). So there's nothing wrong with the COM port because it programs the PIC fine.

    I've tried another computer also, with no different results.

    I have PORTA.1 connected directly (with a resistor) to the RX pin on the serial port COM1 (pin 2 if I remember correctly) and using Hyperterminal for the time being.

    Do I use 'Driven True' (T300) or 'Driven Inverted' (N300)?

    skimask, you suggested Driven True. Is this right for my setup?

    Thank again.

    If your pic is directly connected to the PC, you need inverted (idle low)
