During the development you need to use minicom to install Linux kernel, format filesystem and configure device. This device connected to my computer using DB9 null modem cable. The soekris embedded Linux / BSD board with AMD 266 Mhz CPU + 256M RAM. (Fig: 05: minicom connected to one of my embedded Linux device via null modem cable ) Once connected power on device and type minicom command without -s option: You need to connect your serial device such as router or modem using modem cable. (Fig: 04: minicom command help summary) minicom in action To activate help menu press followed by for help on special keys: Press A to setup serial device name such as /dev/ttyS1.You can add MINICOM variable to your shell startup script such as ~/.bash_profile. Minicom will assume that your terminal has a Meta or key and that color is supported. When minicom starts, it first searches the MINICOM environment variable for command-line arguments, which can be over-ridden on the command line. but it does respond to AT commands after that. alas mine still needs to run the command as root using sudo minicom b 115200 D /dev/ttyACM0. replace where it says /dev/tty8 with /dev/ACM0. (Fig: 02: minicom in configuration mode with color console) then go use the arrows to select serial port setup. Type the following command start minicom with colours: Some terminals such as the Linux console support color with the standard ANSI escape sequences. Type the following command at shell prompt: Use setserial command to set and/or report the configuration information associated with a serial port. # yum install minicom How do I use minicom?įirst, make sure Linux has detected serial ports. If you are using Red hat Linux (RHEL) / CentOS / Fedora Linux, enter: Use apt-get under Debian / Ubuntu Linux, enter:

Let us see how to configure minicom for my Soekris net4801 Single Board Computer / embedded Linux device. => Multiple users with individual configurations => Support for UUCP-style lock files on serial devices => Connect to Cisco routers for configuration => Connect to embedded Linux / BSD device via null modem cable => Access a computer / server if the LAN is down If you are addicted to DOS / Windows TELIX (a telecommunications program originally written for DOS and was released in 1986), minicom is for you under Linux / UNIX. My favorite is minicom – friendly menu driven serial communication program. Linux comes with many serial text and gui based serial communication programs.
