Hi people, could some kind soul show me some code to detect the status of the CD line (carrier detect) on the modem/serial port. I've looked in the RKM: libraries and devices V1.2 but haven't been able to find anything that would work. At least I don't think I have. Does the io_SerFlags have anything to do with it? Seems that these only set it???? Thanks! A0NJ@UNB.CA

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).
