Hi,
I am trying to use rtkrcv (for the first time) in librtk with a oemstar
board. I think the oemstar is compatible with oem4. I have used oem4
in rtkrcv.conf. rtkrcv appears to be communicating with the oemstar
because when I issue status and obverv commands, I see satellites, but
no valid satellites.....

rtkrcv> error
17:28:32.00: point pos error (lack of valid sats ns=4)
17:28:33.00: point pos error (lack of valid sats ns=4)
The only setup I am doing on the oemstar is changing to 57600 baud...
COM COM1 57600 N 8 1 N OFF ON
Then I close the terminal and start rtkrcv with the attached rtkrcv.conf
file...
./rtkrcv -o rtkrcv.conf -t 2
Any suggestions for a newbie?
