the FT232RL driver
To verify if the
FT232RL driver is properly installed and determine the COM port assignment of the
FT232RL by Device Manager:
- Go to
Manager. Double-click on Ports (COM & LPT1).
In the following picture you should see the
USB Serial Com Port (COM4) under the Ports. This also means that the Device
has assigned the adapter to COM4 port.
The COM port assignment of the USB to Serial adapter varies on your PC
Device Manager will randomly assign a unused COM port number to the
COM4 is just an example here and it could be a different COM port on
adapter can be assigned to different COM port numbers by different PCs
IDE software in your PC might not work with COM4 so you may need to
reassign the COM Port of FT232RL to another port
number to work with your IDE. You can double-click on the device shown
on the above picture, USB Serial Com Port (COM4) to view
properties as shown below:
reassign the COM port number, click on the Port Settings tab,
then click on the Advanced button.
Inside the Advanced Settings, you will see the COM port number,
latency timer, settings for Receive Buffer
and Transmit Buffer
Click on the COM Port Number and check what
other port numbers are unused. If you know what COM port that the IDE uses in
your PC, you can just reassign the COM port of the adapter to that COM
port number, otherwise you may try to reassign it to COM1 or COM2. Click OK when finished. If your PC indicates that COM1 or COM2 are not
available but you know they are available, you can ignore your PC's warning and
just select COM1 or COM2 anyway.
