| 30 | .SH DESCRIPTION | |
| 31 | .I Lptest | |
| 32 | writes the traditional "ripple test" pattern on standard output. | |
| 33 | In 96 lines, | |
| 34 | this pattern will print all 96 printable ASCII characters | |
| 35 | in each position. | |
| 36 | While originally created to test printers, it is quite | |
| 37 | useful for testing terminals, | |
| 38 | driving terminal ports for debugging purposes, | |
| 39 | or any other task where a quick supply of random data is needed. | |
| 40 | .PP | |
| 41 | The | |
| 42 | .I length | |
| 43 | argument specifies the output line length if the the default | |
| 44 | length of 79 is inappropriate. | |
| 45 | .PP | |
| 46 | The | |
| 47 | .I count | |
| 48 | argument specifies the number of output lines to be generated if | |
| 49 | the default count of 200 is inappropriate. | |
| 50 | Note that if | |
| 51 | .I count | |
| 52 | is to be specified, | |
| 53 | .I length | |
| 54 | must be also be specified. | |
