No GPS Found on Panasonic CF-19

Try com 4, 5 etc. You will see on the setup setting the port that is in use, do not use those only the free one. Try one at a time, btw. in com 3 did you set resources too to what I instucted. Do it also one at a time until you hit the jackpot, Lol.

Ok, I'll try other com ports.
Sorry, English not my native language, I didn't find your instructions about changing resources on COM3 so I changed configuration, when I already changed COM3 to COM7

Same here , man! English is not my mother toungue too! but that is not a problem. They are all good people here.

Thanks
I'll try to check hardware tomorrow and try other COM ports, I've deep night here already...

Ohlip, I am suspecting it is his antenna, or antenna cable. It sounds like his GPS engine is working fine, and you have him on what should have been a non-conflicting COM port. We should try Mnem's trick of twisting the antenna connection on the PCB back and forth to ensure a good connection that is not dirty and maybe keep it outside with a good clear view of the sky and the antenna cover off?? COM3 or COM7 sounds like the correct choices with your alternate configs; we just need a signal to get to the unit now (hence the antenna).

What do you think?

I'll try to reconnect antenna cable to GPS board... Here is two images of my notebook inside

I'd try plugging the patch antenna cable directly onto the GPS board just long enough for a testing session outdoors. Of course, reassemble/reconnect the GPS board.

Remove everything that isnt a GPS...

You mean remove BT and 3G board?
I plugged cable directly on GPS board, reconnect connecting cable that connect GPS with sound board...
I removed BT and 3G board and start GPSinfo with only GPS board connected, still no effect... unfortunately the weather is cloudly here and I cannot try notebook outdoor on clear aky

Clear sky refers to no solid obstructions, trees, buildings, bridges and the like. really heavy weather like major snow or really heavy rain will degrade the signal a bit but the GPS should still stream data, even before it finds its first satellite.

Ok, thanks. I'll try to test GPS outdoor... hm... my Samsung wave internal GPS doesn't work too... so I need outdoor test of both gadgets

Sorry. My postscript was meant as a joke; like what the stonecarver says when someone asks how he did it. "Start with a block of stone, remove everything that isn't a (whatever the heck we're talking about)."

It wasn't meant as actual direction at this point; I'm unsure whether removing those things can disrupt the data path you're trying to identify.

GPS will stream data whether it has a satellite signal or not; it's a simple serial datastream, so even frames with no useful data will contain the header and tail that defines the frame, as well as identifier information specific to the device.

I suggest you try connecting to each Com port using HyperTerm or PuTTY; you'll see a repeating datastream that updates regularly whether or not you're moving the cursor or typing on keys, and it should have an identifier string that includes the GPS model/chipset name.
