Minicom is a Linux terminal emulation program that allows for serial communication between a microcontroller and computer for testing and analysis. It can be used to configure Linux boards and run TFTP servers. The document provides steps to set up Minicom for serial communication on a Fedora 9 system, including selecting the serial device and baud rate, saving the configuration, and running Minicom to see a "Hello World" message from a connected microcontroller.

1. Minicom is a text-based modem control and terminal emulation program for Linux operating systems,
originally written by Miquel van Smoorenbur. Minicom (Hyperterminal in Windows) is easy and effective
used for serial communication between Microcontroller for Testing and Analysis Purpose. Minicom helps
you in Configuring Linux on Board, Running TFTP Server and others.
Although, Minicom is very much Similar HyperTerminal in Windows. But its configuration in quite tricky
then of HyperTerminal.
In this document, you can see How to Set Up Minicom for Serial Communication.
Log in as Root in Linux (almost common for all Variant this particular in fedora 9)
Step 1: Go to System Tools>> Terminal
You will see following windows:

2. Step 2: Type minicom -s (No need to download from Net already in Fedora 9) You will see following
windows:

3. Step 3: Go to “Serial Port Setup” using Up/down Keys

4. Step 4: For Change Setting
Press A: Select ttyS0 for Serial Device (Same as COM1, COM2 in Windows).
Press B: Select Lock file location (as Home Folder) to avoid any access restrictions.
(userabc as other than root)
Press E: Bps
Press F: Hardware Flow
Press G: Software Flow

5. Step 5: Press C for Bps
Change the Baud Rate According to you. We Generally Use 9600 8N1

6. Step5: Now Press Enter then Save as dfl.

7. Step 6: Wait for Configuration saved.
Step 7: Type Minicom

8. Step 8: Wait for Initialization Modem

9. Step9: You will See Hello World!! As same Program (in Microcontroller) as you see in
HyperTerminal in Windows. (It is assumed that you have connected any device to serial
portl which is sending hello world string at serial port)
