AUX Serial Port

RonRioux1

I have an app that requires writing out a short string to the AUX Serial Port but I am having trouble getting started.  The documentation states: "The AUX functions are only called if the layer has declared that it requires the use of the AUX serial port."  However, I have not been able to figure out how to get a layer to declare that it requires use of the AUX port.  Any help in pointing me in the right direction would be greatly appreciated.

Hello Ron,

Not sure you're aware ArcPad Studio Help is now Online as announced earlier this month on ArcPad Team Blog. I suggest reviewing documentation on ArcPad Layer Definition File Schema, AUX event and OnClose, OnComm, & OnOpen attributes, and COMPORT element as well as the sample ArcPadPrefs.apx.

Here is a sample from past DevSummit presentation - Read and Parse AUX port example:

function ReadAUXForTemp ()
{
// called in OnComm event to read data from AUX port

  // read from the AUX port
  var strRawData = AUX.ReadLine();

  // parse the comma-delimited data
  var arrParsedData = strRawData.split(",");

  // if data is valid, return the temperature
  if (arrParsedData [0] == "$PTEMP")
      return (parseFloat(arrParsedData [1]));
  else
      return (NaN);
}

Hope this helps get you started,
Denise
