Greg,

    Funny you should ask about how to detect the CD line through
    the serial device, I too am about to do it....  Anyway, it looks
    like you need to send the serial device a CMD_QUERY command
    and then look at the io_Status word when the command completes.
    Bit 5 is the Carrier Detect (active low).

Regards,
