shr- GPS howto?

[Fernando Martins]

No luck:

- I've setup date and timezone;
- GPS is on, per /sys/class... incantation
- demon fso-gpsd is on, checked with ps
- telnet comunicates with gpsd but no good data
- tangoGPS doesn't find GPS device

I have no idea of the reception capabilities of om (or GPS devices in 
general): is it supposed to work indoors?

Any further suggestions?

Thanks for all the help so far,
Fernando
