When you troubleshoot issues with a serial device, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
Sep 20, 2019 The chipsets for USB slave converters, manufactured by Future Technology Devices International, are able to convert any RS232 port data to Universal Serial Bus (USB) port. Each FTDI adapter contains a USB microcontroller which talks a proprietary protocol via USB and transforms that into the regular UART signals and vice versa. Industrial FTDI USB to High Speed 921.6kbps 1 port RS232 Adapter converter with 10cm Cable Windows 10 driver supports USB-A.

To test your setup components, try the following:
Usb To Serial Ftdi Driver
Use the serial cable, serial port, and serial device in another setup to see if the problem is with the components or the setup.
Use a different serial cable, serial port, and serial device in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
When you test your cables, it is recommended that you do the following:
Ftdi Usb Serial Port Remote Desktop Windows 7
Test each cable individually.
Use short cables when you are testing.
When you test the serial ports and serial device, it is recommended that you do the following:
Press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager. Check to see if your device is listed under Ports (COM & LPT).
Make sure that the COM port number is the correct number for the serial device and that the software being used to connect the computer to the serial device uses the correct COM port number.
If you do not see the COM port number in Device Manager see this FAQ for PCI/PCIe expansion cards: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#pci-pcie-cannot-boot-os-or-detect-windows
or this FAQ for USB devices: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#usb-cannot-detect-windowsIf the device is listed with an error, follow the instructions on the website to reinstall the drivers.
Note: Some serial devices work only if the COM port number is between a certain range. For example, COM1 to COM4.
