Description
Sets the data available handler for this serial port.
When new data arrives, this script is called, so you can call SerialPort.Read functions.
Be aware that script may be called when just a few bytes are in the read buffer. So the data message you wait for may only be available partly. In that case, please read available bytes, check if whole packet/message arrived and if not, store read data for later and wait for next script call.
With plugin version 6.0 or newer the script name can be a script ID number. In that case the plugin queries the script name for the given script ID. This allows to call scripts by ID and avoid problems if scripts are later renamed.
FileMaker 19.2 adds a fmplugin extended privileges. You my need to add such an extended privileges to allow the plugin to trigger scripts. See FileMaker product documentation for details.
Examples
Set data available handler script:
MBS( "SerialPort.SetDataAvailableHandler"; $port; Get(FileName); "SerialPortDataAvailable" )
