Minicom for linux

Standard starting of minicom:

$ minicom -c on -b 115200 -D /dev/ttyUSB0
minicom: невозможно открыть /dev/ttyUSB0: Отказано в доступе


$ minicom 
Device /dev/ttyUSB0 access failed: Permission denied

Therefore minicom is to be started with root permissions.

Starting minicom without root privileges, without password entering:

The output of ls command displays why it happens. You can access the device
/dev/ttyUSB0 if you are a member of the dialout group.

$ ls -l /dev/ttyUSB0 
crw-rw---- 1 root dialout 188, 0 авг.   5 13:13 /dev/ttyUSB0

Let's add ourselves to the dialout group by using of the command named usermod and then let's reload the system

$ sudo usermod -a -G dialout $USER
