![]() Custom configuration names will be saved as.If, on the other hand, you navigate to the configuration menu after having started minicom without the -s flag, then minicom will save the configuration files to your home directory. If you pass the optional flag -s which starts minicom directly in the configuration menu, then Minicom’s behaviour is to save the configuration to the compiled in directory only, regardless of whether or not you are running as root.Minicom has some quirks when it comes to saving and loading configuration files. The configuration directory for the access file and the configurations We can look up the required group membership using the ls command. This is achieved by adding the correct group membership to our user account. Our user account requires rw permissions to initiate a connection with the device. ![]() The rest of this blog post will simply use ttyUSB0 as the name of the serial port, but you must use the correctly named serial port assigned to your connected device if you are following along. The device name for a serial connection is properly referred to as a serial port. Also, the index number at the end of the name is determined by the devices minor number and may not be 0. There are more serial port names than I mention here. If your system architecture is ARM, you might see a name like this ttyAMA0 and if it is a Samsung, then the device might be named ttySAC0. In my case the TTY device name was ttyUSB0 however, if your cable is not a USB converter, then it might be named ttyS0 instead. usb 1-2: FTDI USB Serial Device converter now attached to ttyUSB0 ftdi_sio 1-2:1.0: FTDI USB Serial Device converter detected The modem initialization strings, set the variables 'minit', 'mreset', and 'mhangup' to be emtpy.Usb 1-2: Manufacturer: FTDI (Which can result in gibberish being output on the serial line). If modem initialization strings are used, this may confuse the kernel console initialization But when using minicom with a kernel serial console, To create a serial connection over a modem. To turn off the modem initialization strings for minicom. To access these, you would use 'minicom arm' or 'minicom mips' at theīesides serial port settings (the most common being 115200,N,8,1), it is often necessary For example, you can have /etc/minirc.arm which has the settings for theĪRM serial connection, and /etc/minirc.mips which has the settings for the serial connection The host via a USB/serial converter, then you can have different minicom config files Is connected to the first serial port (UART) of the host, and the other is connected to Each config can have the port and settingsįor the different connections, and you can refer to them by name.įor example, if you have an arm development board and a mips development board, and one Refer to different serial connections by name. This is handy if you have different targets connected to your host and need to You can have several minicom configuration files, for different serial hardware on your The configuration files for minicom are located in /etc, with a name prefix of 'minirc.'. To avoid this, use the '-w' command line option. ![]() See serial console for information on configuring the kernel for serial console support.īy default, minicom will not wrap longs lines of text, which causes them to run off the edge of The kernel console, on the target's serial port. It is included with almost all Linux distributions, so it should be readily available.Ī very common use of Minicom during embedded Linux development, is to communicate from the host machine to It has a dialing directory and auto zmodem download. Minicom is a menu driven communications program.
