Thanks for the help. But I'm not sure I did this right.
I double clicked the.exe file and ran the application from my downloads folder. I got a warning saying that the drivers I was about to install were older than the ones already had. So I chose NOT to install them. Then, I went to the device manager, right clicked the PCI Serial Port, then chose update driver. I browsed to the new folder and and Windows 10 said that the device was properly installed.
However, the device changed from PCI Serial Port to 'Intel(R) Active Management Technology -SOL (COM4)' Did I do this right?
Data communication between electronic devices is inevitable in many electronic projects and brings a lot of advantages to your project i.e. Connecting your microcontroller to PC and monitor data on a large colorful display instead of small monochrome LCD. When talking about connecting a device to PC, the most obvious way of communicating is USB port.
But transmitting data over USB requires lots of programming. Another easy way is Serial Port (aka COM) and RS232 protocol that only needs a tiny electronic circuit to convert voltage levels and a little programming. So I made an RSS232-TTL UART adapter and published to uses in all of my projects. But I faced a new problem, new motherboards and laptops have no COM port. Then I decided to make a using famous FT232 IC for my projects. It works very well, but long wires from devices to PC are annoying me. Is it possible to have the serial port on the air like wireless mice and keyboards?

Of course, it can be done using lovely WiFi module ESP8266, and by using WiFi you have not to make a dongle yourself and also you can have a serial port over the internet. Wow, I just wanted a wireless serial port, now I also have a serial port over the web.
That's very exciting. The video shows controlling an E-waste CNC (3D printer) using this device.
I want to share this project with you. If you like it, follow me. Print the PCB file with a laser printer on an A4 glossy paper without scaling. Cut some copper board, clear it with sandpaper, pour some acetone on the board, put printed papers on it and press them about 10 seconds and wait till it dries. Remove the papers, if there are parts that circuit does not reflect well fix them with a CD marker. Then soak board in ferric chloride etchant and wait till no copper parts can be seen. Wash the board with water, dry and clear it with sandpaper, then drill the holes.
There are a lot of Instructables to show you how to make a PCB. Attachments. I placed two connectors for the power supply (one male and one female) to be able to put this device easily between AC adapter output and the set that must connect to the serial port, so you have not to prepare another power source for this device. According to LF33CV datasheet, you can power this device from 3.5VDC to 18VDC. Connect 3.5mm audio connector to the serial port of target device, and male power connector to the power supply of target device.
Plug AC adapter output into 'Serial Port over WiFi” DC input connector. On your PC connect to “dihavSerialPortXXXXXX” access point, device IP address in access point mode is “192.168.4.1”. Download the Windows application I uploaded here, and execute it on your PC. Type device IP, choose baud rate, stop bit, data bits, parity and click 'Connect' button. Click “Allow access” button on “Windows Security Alert” window. You can send data by typing it into the box below 'Disconnect' button as ASCII, hex or decimal and press related 'Send XXX' button. Sent and received data will display in six boxes below 'Send XXX' buttons.
There is an HTML-based interface that makes it possible to access serial port in a web browser on any OS. To access it type “192.168.4.1” in the address bar of your internet browser and hit enter. Attachments. You can also connect this device to a router instead of using it as an access point. To do this just browse to device settings page by typing “192.168.4.1/set” into the address bar of your internet browser. On this page, you can change the device name, access point password and specify the router you want this device to connect to by typing its name and password.
It is recommended to assign a static IP address to this device if you want it to connect it to a router. To find out how to do this just search the internet for “Assign static IP address ”. Note that if you connect this device to a router, the IP address is not '192.168.4.1' anymore.
To reset all these settings hold 'Reset Passwords' button on the device for about 2 seconds. If you want to make a program that directly connects to this device without using the software downloaded from step 6, use the following protocol, I've made for this device. Each is a byte.
Baud rate on port 2321 is a 4-byte value that most significant byte will be sent first. Connect:.
