Find Serial Port Name
=====================

Serial and USB Serial devices use an identifier to identify a port.

.. Note::
   The Optec USB Serial cable uses FTDI drivers.
   These should be installed or will install automatically with Windows Update.
   If the COM Port is not found try installing the FTDI driver directly.

.. Note::
   The Optec ThirdLynx uses USB CDC which is built into Windows 10.
   For Windows 7 installations Optec provides a native driver.

All Platforms

The drivers show the available Serial ports.
Before plugging in the USB cable note what ports are available.
