Remarks
This exception is only thrown after 5 attempts, each with a 1 second timeout, have been made to
acquire the serial port. It may indicate that you have more than one thread attempting to access the serial
port and that you have not synchronised these within your application. The serial port can only handle
one transaction at a time e.g. Serial.Receive or Serial.Transmit etc.
