NAME

       dahdi_test -- Test if the DAHDI timer provides timely response

SYNOPSIS

       dahdi_test [ -v ]

DESCRIPTION

       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 (/dev/dahdi/pseudo).  This should take exactly 8000 ms . It uses calls to 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 pass.  Values of 99.98% and 99.97% are probably OK as well.

OPTIONS

       -v
	      Be more verbose: print one line per test.

       -c count
	      Run for count times instead of running forever.

FILES

       /dev/dahdi/pseudo
       The device file used to access the DAHDI timer.
