Control Linux VMware virtual machine over serial port

It can be useful when you test network communications and you don't want to see SSH traffic in wireshark.
Add serial port to VM
How to add a serial port to your VM is described in detail in this article.
Configure Linux on VM
First, you need to check that you do actually have a serial port:
user@debian:~$ dmesg | grep tty [0.000000] console [tty0] enabled [2.720937] 00:05: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
So here we have one serial port
ttyS0 with baud rate 115200.
Next, we need to enable
getty on this port:
systemctl enable serial-getty@ttyS0.service systemctl start serial-getty@ttyS0.service
That's all. Now we can try to connect.
Connect over serial port with PuTTY
Just choose 'Serial', enter port name to 'Serial line' and baud rate to 'Speed':
