SerialCommunicationTest - send and receive bytes over a com port.

Documentation This is a simple test program for the mitk::SerialCommunication class It opens a com port, sends two strings and receives two messages with different timeout modes - first it waits indefinitely until all characters are received, next it waits not more than 6 seconds. you can use the windows program HpyerTerminal to receive text from this program and send text back to it.
