2 | * This class is one end of a test pair of programs
|
||
3 | * SimpleSnuV1.class is the other end.
|
||
4 | * To run the test requires two com ports
|
||
5 | * and a null modem cable.
|
||
6 | * Start SimpleSnuV1 and then run SimpleRead
|
||
7 | * on the other machine/com port.
|
||
8 | * This code is supplied for demonstration purposes only.
|
||
9 | * You are free to use it as you please.
