(Feeling rather stupid after the blank email, apologies)
I grabbed an older GPS from that Microsoft Streets and Trips software and plugged it into my laptop to try the nmea sensor stuff. The sticker says it's a GPS-360, mfg by Pharos USA with a SiRF chipset. There looks to be a small bug in the dmesg display (it runs into my USB headset): uplcom0 at uhub0 port 1 uplcom0: Prolific Technology Inc. USB-Serial Controller, rev 1.10/3.00, addr 2 uaudio0 at uhub1 port 2 configuration 1 interface 0ucom0 at uplcom0 : Logitech Logitech USB Headset, rev 1.10/10.13, addr 2 uaudio0: ignored input endpoint of type adaptive uaudio0: audio rev 1.00, 6 mixer controls audio0 at uaudio0 uhidev0 at uhub1 port 2 configuration 1 interface 3 uhidev0: Logitech Logitech USB Headset, rev 1.10/10.13, addr 2, iclass 3/0 uhid0 at uhidev0: input=2, output=0, feature=0 After some fiddling trying to figure out the proper port to use: # nmeaattach cuaU0 # sysctl hw.sensors hw.sensors.0=nmea0, GPS, -0.66 secs, WARNING, Thu Oct 19 17:28:19.435 Would I be correct in assuming the warning is probably due to a weak fix by the GPS device? -- Jon
