Tkinter working with COM ports

(or virtual ports (on Linux))

Install program to create virtual ports

$ sudo apt install socat

Use virtual ports

Create portal in one terminal

$ socat -d -d pty,raw,echo=0 pty,raw,echo=0

2016/11/13 16:33:30 socat[18425] N PTY is /dev/pts/5
2016/11/13 16:33:30 socat[18425] N PTY is /dev/pts/6
2016/11/13 16:33:30 socat[18425] N starting data transfer loop with FDs [3,3] and [5,5]

It creates ports `/dev/pts/5` and `/dev/pts/6`

You read from `/dev/pts/6` and write to `/dev/pts/5`

Read in another terminal

$ cat < /dev/pts/6

Write in another terminal

$ echo "Hello" > /dev/pts/5
