Using two Serial Smart Boards, it’s possible to link two modules together using the Serial Link action. The two modules can be anywhere on the Internet forming a virtual connection between them, making it possible to relay messages back and forth and having the ability to access the resources of ioBridge at the same time.
You can also use the Serial Link Action to link one Serial Smart Boards Tx/Rx together. This link would mean any data sent into the serial board will be sent out of the serial board acting as a virtual loop. This would be usefull if you had a serial display attached to the module and you wanted data to be displayed.
