Minicom is a software for serial communication in Linux. Its use relies entirely on the keyboard. Although it is not as easy as a "Super Terminal, however, readers will learn about its efficiency and convenience after getting used to it. The following describes how to install and configure minicom.

Before using minicom, you must first ensure that you have the read/write permission on the serial port. we know that Linux devices correspond to a file in the/dev/directory. the serial port COM1 corresponds to ttys0 and com2 corresponds to ttys1. Use this command to check your permissions on com1:

$ LS-L/dev/ttys0
CrW-RW ---- 1rootdialout4, 642006-05-0406: 52/dev/ttys0

As you can see, its owner is root.
