No GPS or no GPS fix

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Watch Config->System->Internal GPS->SW Port (COM4)
                                     ->HW Port (COM3-4800bps)
2. Start Gcc and config 'Read GPS data directly: COM4, Baud rate:4800
3. Start tracking or set on the GPS

What is the expected output? What do you see instead?
After a while is supposed that any GPS daat will be received but nothing 
happens. The 'Info tap' shows a 'no data from GPS' message and the 'GPS tap' 
shows a red square and a 'no gps data' message. If I config the GPS port to 
COM3 same applies.

If I config Gcc not to 'Read GPS data directly' the 'Info tap' shows now a 
'GPS:On d0 tllahs xxx' message where xxx is an incremental number growing avery 
second. The 'GPS tap' shows a red square and 'S-/- Snr- T- Dh-'. Nothing 
changes but every xxx is 18x the red squares change to grey and again to red 
and the 'Info tap' shows 'gps opening...' (I thought) during an instant.

What version of the product are you using? On what operating system?
I'm using gcc 4.8 over Windows Mobile 5.0 in a ACER C531 ppc.

Please provide any additional information below.
'log raw NMEA' don't produce the tmp.txt file in the root directory so I can't 
see if gcc is receiving any gps data.

Did you have any other SW which uses GPS successfully? Which com port does this 
application use? Usually the hardware port is com1. If you use windows setting 
to split the com data (automatically manage GPS port) for use with more than 
one application, it will be usually com4. But this does not work on my device 
(Asus P320, WM6.1). I use a third party com splitter "VirtComNG.dll 
VirtComMgr.exe  in VirtCom.zip". But try first the hardware port (com1 or 
com0). Sometimes it helps to hard reset the device.
'log raw nmea' only works with 'read GPS data directly'.
If there are errors, a file GpsCycleComputer.log is created in the application 
directory - are there any entries?

Hello Klaus,

* Yes I use other GPS applications successfully, ie TOMTOM6. In this 
application the port that goes is labeled has GPS PORT and if I select COM4 
(which is the applications port in windows config) it doesn't detect the GPS. 
Other SW I use is TwoNav, this software has a more complex GPS config options 
but basically the port used is labeled has 'COM7: GPS Port' NMEA protocol and 
4800bps.... Jo Jo Jo! writing these lines I hav just try the COM7 port and ¡it 
rules!

There were no entries in the log file you mention. I'll go out of the building 
right now in order to see if it can get a GPS fix.

Thanks  Klaus for rapid answer and clever indications.

In a short test I get fixed the position, not so much precise but the GPS in my 
Acer C531 is not very precise...is a Sirf Star III ¿any ideas to improve the 
precision?

Thanks again and if you need something I could do don't hesitate to ask.

Usually after a few minutes GPS operation, it gets more precise.
You can use averaging (AVG = 2 .. 4).
