Hello, i will write in english, my german is not very well, i hope that's not problem I have problem with gps setting in my T5355. Its model with Qualcomm MSM7200A & windows 6.1 pro. Can you help to set correct ports in windows mobile (hardware and software ports)? I've install VisualGPS and try to connect, but nothing happens. VisualGPS detects few ports: COM1: - Drivers\BuitIn\Serial_Modem COM2: - Drivers\BuitIn\Serial_BT COM3: - Drivers\BuitIn\Serial_GPS COM6: - Drivers\BuitIn\Serial_AGPS When I select COM1 or COM6 program communicate error: "Could not initialize communication buffer size" & "Unable to open port. Please close the application accessing the communication port" Can you help with this? Thanks for answers.
