Hi,
I have a time receiver that sends time information in MSTS format to the
serial port of an OpenBSD system.
The receiver sends 1 PPS pulses on the DCD pin and I'm trying to use
these pulses to increase the accuracy (not that a simple DCF77 receiver
will ever be very accurate, but at least I can try to get the most out
of it).
However, there seem to be no difference when I start ldattach with or
without the -t dcd option.
When reading the source of ldattach.c, I noticed this piece of code:
/* line discpline specific setup */
switch (ldisc) {
case NMEADISC:
case ENDRUNDISC:
if (ioctl(fd, TIOCSTSTAMP, &tstamps) < 0) {
warnx("TIOCSTSTAMP");
goto bail_out;
}
tty.c_cflag |= CLOCAL;
/* FALLTHROUGH */
case SLIPDISC:
tty.c_iflag = 0;
tty.c_lflag = 0;
tty.c_oflag = 0;
tty.c_cc[VMIN] = 1;
tty.c_cc[VTIME] = 0;
break;
}
As you can see, MSTSDISC is not mentioned here. I'm not a programmer
and I don't understand much of this, but it seems odd that MSTSDISC is
missing here.
Does this mean that the -t dcd option has no effect for MSTS?
regards,
Maurice
