Sometimes, if the Linux connection, which always connects through Minicom, is lost,the next time you start Minicom, an error may appear:
The / dev / ttyS0 device is locked.
The / dev / ttyS0 alias may differ depending on your COM port.
To avoid such an incredible error, you need to fill in Minicom correctly using the CTRL-A keys followed by the Q key.
You can usually fix the problem by deleting as the new root user with the command:
killall -9 minicom
sudo killall -9 minicom
Or you can simply delete the “LCK..ttyS0” file in the / var / lock / directory. If
Sometimes you lose connection with a device through minicom, next time you start one minicom you may see a fantastic error:
The / dev / ttyS0 device is locked.
The name / dev / ttyS0 may differ depending on the COM port. To avoid this, always turn off Minicom in the immediate vicinity using the CTRL + A keys followed by the Q keys. Correct
Is there way to enable USB debugging on locked Android?
Ok, enough about USB debugging mode, back to the topic, here are each of our effective solutions that you can follow to positively enable USB debugging on a locked Android – whether you have a shared lock password, PIN or what something else., don’t do it. know or remember the pattern, or maybe for some other reason your Android device is locked or unavailable.
That as a Cheer user, your needs can end the process. First I needed to drink a large cup of Latin American coffee. Use the following commands for your terminal :
killall -9 minicom
Likewise in Ubuntu. Run the command in a trusted terminal with sudo:
sudo killall -9 minicom
LCK..ttyS0 in the / var / lock directory.
It was for my eyes! I hope this little tutorial was helpful to you. If you would like to learn more about the network, read this CompTIA Certification network + All-in book – A Guide to exam, 7th edition (exam N10-007)
/ Dev / Console
Why is the device / dev / ttyusb0 locked?
The / dev / ttyUSB0 device must be locked. When checking the list of processes via Playstation, no running gtkterm process was shown. I fixed this by simply removing /run/lock/LCK..ttyUSB0. After that, gtkterm was developed to successfully open ttyUSB0.
On Linux, the kernel console can be further customized with the console = boot option. The kernel calling printk () can send messages to it, for example, when a software download or an error occurs. These messages are also often buffered by the kernel. (See also dmesg ). When the console device is found and started, it will receive all previously buffered messages.
You can pass console = multiple times to any number of configuration consoles, and messages will be written to each one. Obviously you can only select one console of each “type”: you cannot use console = ttyS0 at the same time and console = ttyS1 .
In the kernel documentation, / dev / console is referred to as a character special device numbered (5,1) . This preliminary draft function opens the “main” console, which is the last terminal in the console’s shopping list. The first non-kernel project named init or “PID 1” is created with / dev / console , which is linked to stdout, major error, and stdin …
If there is no problem with any console, running / dev / console returns the error ENODEV (“Not this device type”). the kernel will print and still run init . For a sample kernel for a non-TTY console, see netconsole or my favorite console, the line laser.
You can also view the marketing mailing list from tty consoles by reading / sys / class / tty / console / active . The systemd documentation states that the first base block displayed is the main console. The list is in reverse order from the kernel command line. In the current documentation, poisonIt is incorrectly indicated that this last device shown is a potentially “active” master console. For some reason, it is also possible to query this file to get changes (if the console tools were removed?).
The container systemd-nspawn replaces the standard database / dev / console with a pseudo-terminal device (PTY). They are best described as virtual terminals. They are specifically designed to be dynamic, and are also used to define graphical terminal emulators, such as the GNOME terminal, in action, combined with remote access, such as ssh .
/ Dev / Tty0
Linux TTY device nodes tty1 through tty63 are embedded terminals. They are also called VT or virtual consoles. You are modeling multiple consoles in terms of a physical console device driver. Only one virtual console is displayed and refined at a time. The active fatal signal can be toggled, for example, using chvt , Ctrl + Alt + F1, or the number of function keys available to clients.
You areYou can also read and write to check the current VT with / dev / tty0 . tty0 will probably be a normal kernel console, for example, you didn’t select it explicitly inside. The system “looks for the VGA card [using VT] first and then the serial port.” You can also directly configure the console to a specific E vt, eg. console = tty1 .
“If your software may not have a vga card, the first serial port will automatically become the console.” A “sequential game system” such as ttyS0 is probably the most common
code> tty0 . It is not intended to be used by a VT system on a serial console.
/ Dev / Tty
/ dev / tty is one of the three standard device files specified in POSIX ( / dev / is one of the third directory names specified in POSIX). Opening corresponds to opening the terminal for monitoring the current process. When development is stopped, the control terminal opens the terminal first, at least through Linux. For example, in init , the house will refer to / dev / console .
Disable The running control from the terminal is one of the steps usually required to start a background process, such as starting the syslog daemon. The steps that become a background process would be terribly complex, but our own step that does not involve checking the airport is the setsid system call. On more modern systems, a boot system like systemd starts a service without a management port.
What does LCK..ttyusbx mean in serial port?
Moral of the story: If you try to connect a development board (or anything that can access a later port) to your system, it will automatically generate a file named LCK..ttyUSBx (x – 0..9) Worry / var / lock /, which contains the corresponding process ID associated with the process started using the port.
