Connect COM port using windows terminal

Is there any way to connect and communicate with a COM port (e.g. COM4) using windows terminal (Windows 8 <) inbuilt commands or using a batch program?

MODE COM4:9600,N,8,1,P

Above command displays the confugurations of COM4. But how I can send or receive data?

Identify connected COM ports:

mode
powershell -c "[System.IO.Ports.SerialPort]::getportnames()"

Send message with CR/LF:

echo hello >COM4

Send a file:

type file.txt >COM4

Read COM port:

type COM4

The better interactive way is to use Putty or minicom from within WSL 1!
