| 2 | * This class is one end of a test pair of programs
|
||
| 3 | * SimpleRead.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.
