I can't switch my LD-3W to SiRF protocol in SirfDemo. It is connected, NMEA data is transfering, but it is stoped when I try switch to SiRF protocol, and I see the message "Error... Cannot create UART handle. Comm port is not available or may be in use."
I tried connect with Leadtek GPS Monitor (I don't have other software like SirfDemo and this), so it was connected, switched to SiRF protocol, Leadtek GPS Monitor received SiRF settins from GPS, but when I change any settings, switched back to NMEA and disconnected no changes is saved. I reconnect again and see the old SiRF settings.

Welcome
Your question isn't clear. First you say you can't switch it to SiRF protocol then you say you can't switch it back to NMEA from SiRF. Or is this a problem with the two apps you are trying to use?
The first error (NMEA data stops when in SiRF) is to be expected. The error you say is shown could be that the com port you are using can't handle the binary SiRF data - but that doesn't seem too likely as you can apprently see SiRF data with the Leadtek s/w. (You ARE seeing valid SiRF data in this mode aren't you?)
Unless you have very specific reasons for running SiRF protocols then the recommendation would be to leave it in NMEA mode to guarantee wider operability with GPS apps.
As for switching it back to NMEA- do you have to 'store' the new settings before quitting the app - or power cycle the device.
If you can't get it back to NMEA - remove batteries or leave on, to dischage internal batteries, leave for a day and try again. This usually resets the device to the factory defaults. _________________ Phil

Yes, this is a problem with two apps. I can't switch LD-3W to SiRF protocol with SirfDemo, but I can with Leadtek GPS Monitor. So, then I say about Leadtek GPS Monitor.

I set new settings (I can see the new values in the Response View window), switch back to NMEA and then exit the app. I don't see any "store" button or menu command in the app.

LD-3W UserGuide says that I can press power button for 10 seconds to reset the device.
Thanks. I'll try to use the apps listed in the linked post.
