Does anyone know if it is possible to get LabView (ver 7.0) to look at the individual RS232 pins. I am wanting to detect a switch operation without the use of a DAQ card by monitoring the RTS or CTS line. I am not sending or receiving specific bytes of information. Just wanting to detect a voltage. Any assistance will be gratefully appreciated.

Does anyone know if LabView 7 allow access to read the individual pins of the RS232 (serial) input? I am wanting to write a vi which will detect a pulse, measure its duration and increment a counter. I would like to connect the input switch directly into the RS 232 socket and read one of the lines (RTS or DTR for instance) rather than taking in a byte of data. Any help or opinions will be gratefully appreciated.
