| 19 | .SH DESCRIPTION | |
| 20 | .I Lptest | |
| 21 | writes the traditional "ripple test" pattern on standard output. | |
| 22 | In 96 lines, | |
| 23 | this pattern will print all 96 printable ASCII characters | |
| 24 | in each position. | |
| 25 | While originally created to test printers, it is quite | |
| 26 | useful for testing terminals, | |
| 27 | driving terminal ports for debugging purposes, | |
| 28 | or any other task where a quick supply of random data is needed. | |
| 29 | .PP | |
| 30 | The | |
| 31 | .I length | |
| 32 | argument specifies the output line length if the the default | |
| 33 | length of 79 is inappropriate. | |
| 34 | .PP | |
| 35 | The | |
| 36 | .I count | |
| 37 | argument specifies the number of output lines to be generated if | |
| 38 | the default count of 200 is inappropriate. | |
| 39 | Note that if | |
| 40 | .I count | |
| 41 | is to be specified, | |
| 42 | .I length | |
| 43 | must be also be specified. | |
