OpenBSD + gpsd + Garmin Geko 201



Here are my notes on getting the
Garmin Geko 201 GPS handheld working with the OpenBSD gpsd port.

On the Geko 201:

1) Page to and select "Setup" option.
2) Select "Interface" option.
3) Set "I/O Format" to "NMEA"
4) Set "Baud" to "4800"

I'm using a serial to USB converter (unknown type) that looks like:

uftdi0 at uhub4 port 1 "FTDI FT232R USB UART" rev 2.00/6.00 addr 2
ucom0 at uftdi0 portno 1

The associated device file for this ucom(4) is/dev/ttyU0 which I provide to gpsd:

dennis@ipa:~$ sudo gpsd /dev/ttyU0
dennis@ipa:~$

Then I test everything with the cgps (no command line options) client.
