dahdi_test \(em Test if the DAHDI timer provides timely response
.SH "SYNOPSIS"
.B dahdi_test
.I [ \-v ]
.SH DESCRIPTION
.B dahdi_test
dahdi_test runs a timing test in a loop and prints the result of each loop.
The test is as follows:
It reads 8192 bytes from the DAHDI timer device (\fI/dev/dahdi/pseudo\fR).
This should take exactly 8000 ms . It uses calls to
.I gettimeofday(2)
before and after that read to check that indeed exactly 8000ms have passed.
Values of 100% and 99.99% Are normally considered a definite
.I pass.
Values of 99.98% and 99.97% are probably OK as well.
