How Do You Deal With Dev / Ttys 1 I / O Errors?
Table of Contents
Approved: ASR Pro
Over the past week, some of our users have encountered the known dev / ttys 1 I / O error message. There are several factors that can cause this issue. We’ll look at them now. g./ dev / tty represents the specific controlling terminal (if any) for the current process (the process that uses “/ dev / tty” to refer to the command). To find out which specific ttys are connected to which processes, use all the “ps -a” commands in the host shell (command line). As far as the development of the shell you’re in, / dev / tty is the terminal you’re actually using right now.
An I / O error is a generic error message indicating that there is constant activity between different instances. This indicates a problem with the file system, in particular, the operating community cannot access a certain part due to the hard disk (or virtual hard disk).
I am currently getting an “I / O error” when trying to access / dev / ttyS1 on my board.
I am using Ubuntu 18. In 2005 I installed my own kernel with the correct https://wiki.up-community.org/Ubuntu#Ubuntu_18.04_installation_and_configuration
Also in my dmesg output there was no mention of / dev / ttyS1, instead it found:
$ is dmesg | grep ttyS
[2.377490] 00:01: ttyS0 – 0x3f8, I / O (irq = 4, base_baud – 115200) – 16550A
[7.364610] 8086228A: 00: ttyS4 – MMIO 0xa171b000 (irq matches 39, base_baud = 2764800) equals I 16550a

I’m new to this variety, so I need you а information. Playing around with the serial ports, I figured out exactly why not echo from one terminal or cat / listen to another using one of the serial / dev / ttyS * ports on my laptop with Ubuntu 15.04. If I just execute cat / dev / ttyS0 it personally gives me an I / O error. Then I tried to do it with pyserial in python. when I

this gives me SerialException: port cannot be configured: (5, 'I / O error')
After searching for Stack Overflow I found this related post Pyserial: Port definitely failed to configure: (5, ‘I / O error)where only one of the guys said your business needs a physical connection to make this possible. I think this is still some kind of cycle that needs to be created. So my question is which physical connection mode is required? If a USB stick or even one does it, I’ll have to spend some time working with the serial interface. It would be great if someone could give a good overview of successful sequencing programming.A private port.
Feel free to decide where to go. People, there is no need to complain about the stupidity of some questions. After all, a lot of people come to this site to find out, and I do
What is Dev TTYS?
/ dev / tty is the controlling terminal type (if any) for this current process. To find out where ttys is appended to which processes, use the “ps -a” command at a shell prompt (command line). Take a look at the “tty” column. For the particular shell process you are in, the next terminal was / dev / tty.

On the other hand, your PC must have two physical Com or Serial ports for this. If you have a port, people can create a loopback connector by connecting in Rx and Tx along the contacts.
If you don’t have a manual port serial number and want to find one, you can use socat to generate a virtual port serial number.

Boot into Try Ubuntu mode on the perfect Ubuntu Live DVD / USB.Open a terminal window by pressing Ctrl + Alt + T.Enter sudo fdisk -l.Usually identify the device name / dev / sdXX for your “Linux filesystem”.Enter sudo fsck -f / dev / sdXX and replace sdXX with the number you found earlier.

Physically, you will need a cable that swaps the positions of the send and receive clamps. This is called a “null modem cable” because it allows two computers to communicate without a decoder between them.
You may also need to add yourself to the “dialout” collective to use the kindom serial number.
Putty is great preparation for testing with sequential plugins – you can have two instances of putty talking to each other and could potentially try to wire putty with oneth side to python on the other.

Finally, sometimes a device daemon is started that imagines all ports to be serialized. This usually takes over and does let them go away after a while, but you may need to let them find and exit if you think you don’t want random functions to poll the modems on your serialized connection.

How do you solve input output error?
In this situation, the first suggestion would be to check / var / log / messages for computer-related warnings (you may see warnings aboutkeys of perception). If you have almost all hard drive problems, try the hard drive value to confirm. One possibility is using smart tools. You will definitely love the Smartool option for fixing the bottom blocks.
