Specify different init strings to them... at least not yet.) To use a UNIX socket for communication the device name must be prefixed with "unix#" following by the full path and the filename of the socket. Minicom will then try to connect to this socket as a client. As long as it cannot connect to the socket it stays 'offline'. As soon as the connection establishes, minicom goes 'online'. If the server closes the socket, minicom switches to 'offline' again. B - Lock file location On most systems This should be /usr/spool/uucp. GNU/Linux systems use /var/lock. If this directory does not exist, minicom will not attempt to use lockfiles. C - Callin program If you have a uugetty or something on your serial port, it could be that you want a program to be run to switch the modem cq. port into dialin/dialout mode. This is the program to get into dialin mode. D - Callout program And this to get into dialout mode. E - Bps/Par/Bits Default parameters at startup. If one of the entries is left blank, it will not be used. So if you don't care about locking, and don't have a getty running on your modemline, entries B - D should be left blank. Modem and Dialing Here, the parameters for your modem are defined. I will not explain this further because the defaults are for generic Hayes modems, and should work always. This file is not a Hayes tutorial :-) The only things worth noticing are that control characters can be sent by prefixing them with a '^', in which '^^' means '^' itself, and the '' character must also be doubled as '\', because backslash is used specially in the macro definitions. Some options however, don't have much to do with the modem but more with the behaviour of minicom itself: M - Dial time The number of seconds before minicom times out if no connection is established. N - Delay before redial Minicom will redial if no connection was made, but it first waits some time. O - Number of tries Maximum number. Minicom will then try to connect to this socket as a client. As long as it cannot connect to the socket it stays 'offline'. As soon as the connection establishes, minicom goes 'online'. If the server closes the socket, minicom switches to 'offline' again. How do I save minicom configuration? You may want to save the configuration as the default whenever minicom is launched. Arrow down to Save setup as dfl and press ‘Enter’. Why does minicom say offline? Minicom is saying you are offline because the DCD Carrier Detect line is low. The minicom settings will need to be changed so that the application will be able to find your device. User developerpc: sudo apt-get install minicom. If minicom has yet to be installed on your Linux machine, use apt-get to install the minicom package. Getting Started With Minicom. Minicom Offline Serial Terminal Windows esp8266 offline/minicom.

2025-04-20With this name as an argument, it will use these parameters. This option is of course privileged to root. Exit Escape from this menu without saving. This can also be done with ESC. Exit from minicom Only root will see this menu entry, if he/she started minicom with the '-s' option. This way, it is possible to change the configuration without actually running minicom.STATUS LINE The status line has several indicators, that speak for themselves. The mysterious APP or NOR indicator probably needs explanation. The VT100 cursor keys can be in two modes: applications mode and cursor mode. This is controlled by an escape sequence. If you find that the cursor keys do not work in, say, vi when you're logged in using minicom then you can see with this indicator whether the cursor keys are in applications or cursor mode. You can toggle the two with the C-A I key. If the cursor keys then work, it's probably an error in the remote system's termcap initialization strings (is).LOCALES Minicom has support for local languages. This means you can change most of the English messages and other strings to another language by setting the environment variable LANG.MISC If minicom is hung, kill it with SIGTERM . (This means kill -15, or since sigterm is default, just plain "kill ". This will cause a graceful exit of minicom, doing resets and everything. You may kill minicom from a script with the command "! killall -9 minicom" without hanging up the line. Without the -9 parameter, minicom first hangs up before exiting. Since a lot of escape sequences begin with ESC (Arrow up is ESC [ A), Minicom does not know if the escape character it gets is you pressing the escape key, or part of a sequence. An old version of Minicom, V1.2, solved this in a rather crude way: to get the escape key, you had to press it twice. As of release 1.3 this has bettered a little: now a 1-second timeout is builtin, like in vi. For systems that have the select() system call the timeout is 0.5
2025-04-03Provided by: minicom_2.7.1-1.1_amd64 NAME minicom - friendly serial communication programSYNOPSIS minicom [options] [configuration]DESCRIPTION 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.COMMAND-LINE -s, --setup Setup. Root edits the system-wide defaults in /etc/minicom/minirc.dfl with this option. When it is used, minicom does not initialize, but puts you directly into the configuration menu. This is very handy if minicom refuses to start up because your system has changed, or for the first time you run minicom. For most systems, reasonable defaults are already compiled in. -o, --noinit Do not initialize. Minicom will skip the initialization code. This option is handy if you quit from minicom without resetting, and then want to restart a session. It is potentially dangerous though: no check for lock files etc. is made, so a normal user could interfere with things like UUCP... maybe this will be taken out later. For now it is assumed, that users who are given access to a modem are responsible enough for their actions. -m, --metakey Override command-key with the Meta or ALT key. This is the default in 1.80 and it can also be configured in one of minicom's menus, but if you use different terminals all the time, of which some don't have a Meta or ALT key, it's handy to set the default command key to Ctrl-A and use this option when you have a keyboard supporting Meta or ALT keys. Minicom assumes that your Meta key sends the ESC prefix, not the other variant that sets the highest bit of the character. -M, --metakey8 Same as -m, but assumes that your Meta key sets the 8th bit of the character high (sends 128 + character code). -z, --statline Use terminal status line. This only works on terminals that support it and that have the relevant information in their termcap or terminfo database entry. -l, --ansi
2025-04-17The first entry specified after all other program initialization procedures are completed. -p, --ptty=TTYP Pseudo terminal to use. This overrides the terminal port defined in the configuration files, but only if it is a pseudo TTY. The filename supplied must be of the form (/dev/)tty[p-z/][0-f], (/dev/)pts[p-z/][0-f] or (/dev/)pty[p-z/][0-f]. For example, /dev/ttyp1, pts/0 or /dev/ptyp2. -C, --capturefile=FILE filename. Open capture file at startup. -F, --statlinefmt Format for the status line. The following format specifier are available: %H Escape key for help screen. %V Version string of minicom. %b Information on connection, such as baud rate. %T Terminal type. %C Cursor mode. %D Device path, possibly shorted to remaining available space. %t Online time. %% % character. Example: "%H for help | %b | Minicom %V | %T | %C | %t" -b, --baudrate Specify the baud rate, overriding the value given in the configuration file. -D, --device Specify the device, overriding the value given in the configuration file. -R, --remotecharset Specify the character set of the remote system is using and convert it to the character set of the local side. Example might be 'latin1'. -7, --7bit 7bit mode for terminals which aren't 8bit capable. 8bit is default if the environment is configured for this via LANG or LC_ALL, 7bit otherwise. -8, --8bit 8bit characters pass through without any modification. 'Continuous' means no locate/attribute control sequences are inserted without real change of locate/attribute. This mode is to display 8bit multi-byte characters such as Japanese. Not needed in every language with 8bit characters. (For example displaying Finnish text doesn't need this.) -h, --help Display help and exit. -v, --version Print the minicom version. When minicom starts, it first searches the MINICOM environment variable for command-line arguments, which can be over-ridden on the command line. Thus, if you have done MINICOM='-m -c on' export MINICOM or the equivalent, and start minicom, minicom will assume that your terminal has a Meta or key and that color is supported. If you then log in from a terminal without color support, and you have set MINICOM in your startup (.profile or equivalent) file, and don't want
