[LinuxPPS] FW: Linux PPS with Garmin 18xLVC using 2.6.35.7 linux Kernel

[Venu Gopal]

Hello Kent,

NTP requires NMEA messages and the PPS signal.
If I am not wrong, the GPS receiver is connected to the PC via USB
(/dev/ttyUSB0),
though which the NMEA messages are read. And how is PPS connected to the PC
if it doesn't have serial ports ?

I have used uBlox GPS receiver with both USB and serial connectivity.
You need to create soft links for NMEA and PPS as shown below:

1. For NMEA data:
ln -s /dev/ttyUSB0 /dev/gps0

2. For PPS:
ln -s /dev/ttyS0 /dev/gpspps0

You need to have PPS signal reaching to PC either over a serial port or a
parallel port.

Regards,
Venu
