[LinuxPPS] gps_nmea error

[Ritter, Nicholas]

Ok...I loaded up minicom, I see the NMEA messages and I see minicom
going online and offline which indicates (if I am correct) that DCD is
being seen on the serial interface which means the serial interface is
seeing the PPS pulse. 

We hooked up a scope to the electronics between the GPS unit and the
serial port (which is just a breakout box containing the LED for PPS
events and power to the GPS via a USB hookup, etc.) and we see the PPS
pulse.

I unloaded the pps related modules and reloaded them and noticed that
the kernel does not see any PPS pulse unless the ktimer module is
loaded, us this the way it should be?

I think that until I can get the ppstest command to show output that
represents an assert and a clear that my problem is in the kernel?

[root at RMSQSN1001 pps]# ./ppstest  /dev/pps0 
trying PPS source "/dev/pps0"
found PPS source "/dev/pps0"
ok, found 1 source(s), now start fetching data...

Thanks Udo for the config example. I have confirmed that my GPS unit is
set to 200ms.
