I'm using the mscomm control to communicate with a newport meter with and RS232 card. I can send and recieve strings to and from the meter. My problem is decoding the signal that I recieve from the meter. Using Hyperterminal if I set the properties to force 7 bit ascii for the incoming string, I get the correct format back. How can I force 7 bit ascii in VB or what can I do to the incoming string to decode it into 7 bit ascii?
