For most devices, the Ports device setup class and the Serial function driver provide the functionality required to operate serial ports and COM ports. To install serial ports and COM ports using these system-supplied components, do the following:
All devices operating in MTP mode are supported. Note: The MTPdrive is not a replacement for the device's factory (or Windows default) device driver. You must be able to connect your device to the computer and have it visible in the Windows Explorer, before it can be mapped as a drive letter using the MTPdrive. Select the VCP (Virtual COM Port) driver type for downloading. Installing the USB Driver: After the driver has been downloaded and saved, right-click on the file and select 'Run As Administrator'. This will launch the driver. Tektronix USB instruments use and require a generic USB Device Driver, referred to as a USB Test & Measurement Class driver or USBTMC driver. USBTMC is a subclass of the USB specification.
Provide an INF file that specifies the Ports device setup class and the Serial function driver as the service for the port.
To configure a serial port as COM port, comply with the requirements that are defined in Configuration of COM Ports.
