You can still do that in Windows 10:

• Run Start > Device Manager

• Double-click the type of device to configure, for example "Ports (COM & LPT)"

• Right-click the device to configure and select Properties

• Select the Resources tab

• Click to clear "Use automatic settings" (it's unavailable and appears dimmed for devices for which there are no settings to configure or are controlled by Plug and Play)

• In "Settings based on" select the hardware configuration to modify, for example "Basic configuration 0000"

• In "Resource settings", select the resource to modify, for example "IRQ"

• Click "Change Setting"

• In "Edit Resource" type the new value and then OK

• Repeat the above for all the resource settings that you want to modify

• Quit Device Manager and reboot.

A COM port is simply a serial communications port. It can have a physical external port, or can connect to an internal device to provide a simple interface for software to use.

In your case the COM port connects to a motherboard management interface, in order for a software tool to manage your motherboard firmware.

"Old" COM ports used a UART that was physically connected to the CPU BUS and used memory addresses to communicate with the CPU. These addresses got associated with particular COM ports so that they were consistently given the same port number.

USB is a protocol rather than a CPU addressed device, as such there is no way to know that one device being plugged in is the same as a previous device. As a result the USB device may get a different identifier when plugged into a different socket and as a result Windows will assign it a new COM port.

How many COM ports there are depends entirely on your system. A modern system may have none at all. A system with USB to serial converters could have hundreds. It depends.

I was unable to directly figure out the problem however went a different route altogether. Since the goal of this question was to connect my Arduino to my computer wirelessly, I decided to use RF transmission instead of bluetooth. In doing this I purchased the following:

Qty    Item  
2      433 MHz Transciever that supports UART (or any frequency so long as both match)
1      USB to UART Converter

I believe that my biggest issue was that I did not have the USB to UART converter. This also may have been the reason my bluetooth modules didn't work as they were simply transcievers as well without the usb to UART converter. Either way, if someone else is trying to have wireless communication between an Arduino and a Windows based computer, I would suggest the RF method instead.

In the command prompt use

mode

Used without parameters, mode displays all the controllable attributes of the CON (console) and the available COM devices (and LPT as well).

Accepts /? switch for basic help:

mode /?

Try this :

1. Open Device Manager
2. Click on Action
3. Select Add legacy hardware
4. Click Next
5. Select Install the hardware that I manually select from a list (Advanced) and click Next
6. Scroll down and then select Ports (COM & LPT), and click Next.
7. Select Manufacturer as per your need (the standard one or default option should work), and then click Next
8. Click Finish
9. Reboot
