How are ASCII Serial Communications handled in a Maple Systems HMI?
The Free Protocol driver along with Macro commands can be used to send and receive ASCII data on an HMI. The OUTPORT macro function is used to send an ASCII string out of your HMI's serial port, and the INPORT macro function allows you to receive an ASCII string to your HMI.
Examples of both of these macro functions are included in the Sample Project "ASCII Serial Communications," and are explained in Tech Note 5126, “ASCII Serial Communication”.
