endrun — EndRun
Technologies native time-of-day message timedelta sensor
This line discipline interfaces serial EndRun Technologies devices.
The line discipline is enabled by the following sequence:
#include <sys/ioctl.h> int ldisc = ENDRUNDISC, fildes; ... ioctl(fildes, TIOCSETD, &ldisc);
The byte stream is unaltered by the line discipline which maintains a timedelta sensor using the EndRun data. The timedelta sensor will appear as endrun* in the list of sensors and the delta (in nanoseconds) between the received time information and the local time can be accessed through the sysctl(8) interface.
The quality of the timedelta is reported as the sensor status:
The status of a second sensor is used to report the status of the device itself using the Time Figure Of Merit (TFOM) character:
