* This class is one end of a test pair of programs

* SimpleRead.class is the other end.
|
|
* To run the test requires two com ports
|
|
* and a null modem cable.
|
|
* Start SimpleSnuV1 and then run SimpleRead
|
|
* on the other machine/com port.
|
|
* This code is supplied for demonstration purposes only.
