.SH DESCRIPTION
.sp
.LP
The \fBlptest\fR utility writes the traditional \fIripple test\fR pattern to
the standard output. In 96 lines, the ripple test pattern prints all 96
printable \fBASCII\fR characters in each position. The ripple test pattern was
originally created to test printers.  It is also useful for testing terminals,
driving terminal ports, debugging, and performing tasks that require a quick
supply of random data.
