This is a small test program which I have had around since we wrote
|
|
the RFC 2783 API.
|
|
|
|
Options:
|
|
-a capture assert flank
|
|
-c capture clear flank
|
|
(if neither -a -c: capture all available flanks)
|
|
-A output on assert flank
|
|
-C output on clear flank
|
|
(if neither -A -C: output on all flanks)
|
|
-e enable echo (all possible flanks)
|
|
-u unbuffered output.
|
|
-v verbose.
|
|
|
|
The output looks like:
|
|
|
|
# ./ppsapitest -C /dev/cuau4
|
|

Columns:
|
|
|
|
assert seconds (tv_sec)
|
|
assert nanoseconds (tv_nsec)
|
|
assert sequence number
|
|
clear seconds (tv_sec)
|
|
clear nanoseconds (tv_nsec)
|
|
clear sequence number
|
|
|
|
(If the -C option had not been specified, twice as many lines would
|
|
be output:
