Trying to download apps but it won't register the fact that my calculator is connected


Use the TI USB Silver cable or a standard USB to Mini USB. The calculator shipped with one or both cables.
Before it can be recognized you must install the drivers. Download TI connect and install it on the computer before connecting the calculator. If you use the Graph link (black cable) you need to have a serial port on the computer.
COM3 is serial communication port. On newer computers (laptops) that port is no longer available.

Modem in use


Try the following:

-Open the Control Panel
-Open System
-Click on Device Manager
-Click on Modems
-Highlight and right click on the listed modem
-Select Uninstall

Close out anything open and Restart.

IF (!) Windows is cooperating, it should 'find a new device' and reinstall the Winmodem (it's only software and a little telephone line matching).

If Windows fails to recognize the 'new device,' you will have to manually reinstall it via the 'add new hardware' path in the Control Panel.

As with any Windows stuff - rotsa ruck!

Missing COM port 1


It is not easy to give you a proper answer. The only thing that I can suggest you is to check TomTom support site. If you use some non Toshiba external device or software the best solution is to check support or FAQ page of device manufacturer.
