= Setting up your serial debug session using kermit =
== Overview ==
C-Kermit is a modem program, a Telnet client, an Rlogin client, an FTP client, an HTTP client, and on selected platforms, also an X.25 client. It can make its own secure Internet connections using IETF-approved security methods. More information at [http://www.columbia.edu/kermit/ columbia.edu/kermit/]

== Setting up connection ==

Start kermit on your host machine in configuration mode:

 kermit -l /dev/ttyUSB0

 C-Kermit>set flow-control none
 C-Kermit>set carrier-watch off 
 C-Kermit>set speed 115200 /dev/ttyUSB0
 C-Kermit>connect 
 Connecting to /dev/ttyUSB0, speed 115200 Escape character: Ctrl-\ (ASCII 28, FS): enabled Type 
 the escape character followed by C to get back, or followed by ? to see other options.

Hint: Create a .kermrc configuration file in your home directory with these contents to set these options each time you connect:

 set line /dev/ttyUSB0
 set flow-control none
 set carrier-watch off
 set speed 115200
 connect

= Setting up your serial debug session using screen =
== Overview ==
Screen is a full-screen window manager that multiplexes a physical terminal between several processes (typically interactive shells). More information at [[http://www.gnu.org/software/screen/manual/screen.html Kermit man page]].

<pre>screen /dev/ttyS0 115200</pre>

= Setting up your serial debug session using minicom =
== Overview ==
Minicom is a communication program which somewhat resembles the shareware program TELIX but is free with source code and runs under most unices. Features include dialing directory with auto-redial, support for UUCP-style lock files on serial devices, a separate script language interpreter, capture to file, multiple users with individual configurations, and more. 

== Setting up connection==
Start minicom on your host machine in configuration mode. As root:

 minicom -o -s -w

# A menu of configuration should appear. Use the Down-arrow key to scroll down and select the Serial port setup option, and press Enter.
# Verify that the listed serial port is the same one that is connected to the target board. If it is not, press A, and enter the correct device. This is /dev/ttyS0 on most Linux distributions.
# Set the Bps/Par/Bits option by pressing the letter E and using the next menu to set the appropriate values. You press the key that corresponds to the value 115200, then press Enter.
# Set Hardware flow control to No using the F key.
# Set Software flow control to No using the G key.
# Press Enter to return to the main configuration menu, and then press Esc to exit this menu.
# Reset the board, and wait for a moment. If you do not see output from the board, press Enter several times until you see the prompt. If you do not see any output from the board, and have verified that the serial terminal connection is setup correctly, contact your board vendor.
