(HelloDevice 13xx or Ethernet-serial devices only)
When this button is pressed, applet or application will send a serial data to specified network device (HelloDevice or any other). If the property "Receive protocol symbol" is assigned, it will wait for the other party to reply according to known receive protocol. You can repeat above procedure by setting "Event repeat" property "True". If the "Event repeat period" is too short (less than around 1000), the event will not happen with expected time period.
Note : When the connected device is HD1100 or HD1200, this component will not have any effects any more.
