In my project, I use a textbox to send a string to a serial port device. I also show the data from the serial port device on the same textbox. When sending data to the device I only need to send the values ​​entered from the keyboard.In short, how do I distinguish between characters entered from the keyboard and data on the textbox?

(I can say that I am trying to make a command client like cmd. The only thing I want is to be able to send and receive data from the serial port device via the same textbox.)
