XPort XPort Serial COM port splitter for Windows XP, Vista and Windows 7 (32-bit only).  Windows 8 now uses a shared sensor interface making XPort obsolete.  Since donations dropped to 3 in 2013 it's apparent that this software has outlived its usefulness.	Custom made timers at low cost.
Compatible with all GPS and Navigation software. Used by Military, Fire/EMS, Police, and consumers everywhere around the world. Recommended by Microsoft, USGlobalSat, Pharos, and others.  GPS and OBD-II DirectShow Filter, MiniCam, and XOBD		Compass. GPS and OBD-II Display plus GPS log playback through XPort.

XPort features:

• Free version is limited to a measly 128 virtual, bi-directional ports for simultaneous application usage.
• New interface for easy access to GPS data.  Develop GPS applications quickly.  Unlimited direct connections. No buffers. No delays. Even allows XPort to be closed while apps are running.  Finding GPS, baud rate, COM port reading, NMEA/SiRF parsing, and hibernation/standby handling is a thing of the past!
• Optimized to use very little memory.  Much smaller than any other solution available.
• Scans and repairs the COM port arbiter to free up unused ports after drivers leave them allocated.
• Scan is only compatible with NMEA 0183 and SiRF Binary protocols, but the splitter handles any form of data transparently as long as it's continuous.
• Fixes most hibernation issues.  Any USB device, including hubs can be automatically stopped and restarted when hibernating.

Version 1.54 -  5/10/13: Proper read timeouts

How to use:
When starting XPort, there will be no window if it's currently installed.  Just a tray icon (that's for rebooting without any annoying popups when it starts).  Double-Click on the tray icon to open the configuration dialog.  Scan for your GPS or set the input manually if you already know, and set an output to an unused COM port, then hit "Enable Ports" and it's ready to go.  This is all automatic on first run. You may now close the dialog.  XPort will continue to run in the task bar and will start when Windows starts (Windows Vista/7 users see note below).  Connect GPS applications to one or more of the new virtual COM ports.  Multiple applications can use the same port or a separate port.

How to uninstall:
      If XPort is running, uncheck "Enable Ports" and close the window, then delete the XPort.exe file.

Notes:

• XPort will auto configure and enable the virtual ports on first run.  No need to do anything.
• VERY IMPORTANT: "Enable Ports" must be ticked in order to use the virtual ports. Other applications cannot receive GPS data without connecting to these ENABLED ports.
• The config window will open if XPort is run a second time (started from 2 places).  XPort automatically runs from the explorer shell startup, so take it out of the Startup folder, your frontend and all the other places it tends to wind up.
• When connected to the input port, you will see status information such as "SiRF Stream | 3D Fix | 4 SVs :59".  This does not mean data is being sent to the other ports.  The ports must also be enabled.
• iGuidance users must choose at least one single digit port number in the virtual ports on XPort and use that for iGuidance.  Otherwise iG will truncate to 4 characters, saving "COM234"  as "COM2" in the registry.
• You must take the files out of the zip and put them on your hard disk in order for it to work properly.
• Cursor sometimes jumps all over the screen clicking left/right?  Here's the fix:  Open Regedit. Navigate to
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SerMouse, and change the value "Start" from 3 to 4.  Reboot.
        Or click here and Open
• When running under Windows Vista or Windows 7 you will need to give XPort Administrative rights.
• If you see "This application is being blocked by another computer" by a firewall installed on your computer, click "Unblock."
• XPort does not enhance or hinder reception or satellite locks. Getting a faster or slower fix has no relation to the use of XPort.
• Multiple applications on the same port may not function if they don't open the port as shared (if 1 appears to not read anything).  Use a separate port in this case.

Find GPS Click this to scan all ports and locate an NMEA or SiRF GPS.  Yes, it may only take 1-2 seconds but scans all 255 ports. Enable Ports Click this to enable the virtual port driver which all external application can connect to. Select any of these ports in your navigation app instead of the original GPS port. The 8 ports below are the assigned virtual ports.  The indicator to the left of each are green in the center when 1 or more applications are using the port. The outer ring will flicker red/blue when applications are reading from it. Input Port/Baud Rate are assigned to the GPS.  The indicator next to it will be green when connected and flicker when data is being read. NMEA Filter filters all noise/non-NMEA/SiRF data from the virtual ports. Read Only (2-8) allows only the top port to send data to the Input Port. Other ports are read-only. Battery Saver keeps XPort from opening the GPS when no virtual ports are in use, mainly for battery powered bluetooth GPS devices. Video Reset briefly turns the monitor off and back on.  This helps in the car PC when the monitor is blank when starting or resuming Windows. Auto Time Sync sets the system time with GPS time when a fix is acquired. Just below these is the log output.  Enable the check mark to start logging data from the GPS. The device list at the bottom works much like DevCon, and is for devices that have trouble with hibernation.  Check only the devices you have trouble with.  XPort will stop the driver before hibernation, then start after resume, then retry any driver that fails to start a few seconds later. Use with caution.  Some devices may freeze XPort or fail to disable or enable.  Test each device by disabling/enabling in Device Manager. The status line shows current status: NMEA, SiRF or Unknown data.  "No Data" if it's not reading or times out. The seconds display is data, it's not tied to any clock even though it may look like it. Use this to verify speed and accuracy of data throughout the stream.

Tray Status Icon: Black=Not Connected  Connected-No data   Valid GPS-No Fix   2D Fix  3D Fix

MTKSet instructions:   Mediatek MTK chipset only   i.e. i-Blue GM-2

    Apparently the manufacturer software (GpsView) has inaccurate bandwidth calculations and the AGPS update doesn't work.  i.e. notice no change when adjusting sentence frequency.
    The rest appears to work.

    With XPort running and connected to the GPS, start MTKSet and select desired option (Baud rate, Update rate, NMEA frequency) and click the associated button to the right/below.

    DO NOT set set combinations that will use more than 100% bandwidth.

    Note: For MS Streets & Trips, if not using XPort use 4800 baud and 1Hz only.  Or use XPort to allow for higher speeds.
