Over the past week, some of our users reported that they had an I / O error dev / ttys 1.
PC running slow?
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.

I feel like I’m getting an “I / O error” when trying to access / dev / ttyS1 on this card.
I am using Ubuntu 18.04 and I have installed a suitable kernel as well, staying at https://wiki.up-community.org/Ubuntu#Ubuntu_18.04_installation_and_configuration
Also, my dmesg output does not show the status of / dev / ttyS1, instead only this can be found:
$ dmesg | grep ttyS
[2.377490] 00:01: ttyS0 on I / O 0x3f8 (irq = 4, base_baud means 115200) is 7 16550a
[.8086228A: 00: 364610] ttyS4 – MMIO 0xa171b000 (irq = 40, base_baud = 2764800) – 16550A
When I restart the BIOS settings screen, it might appear that the pins were correctly assigned to UART1, so it looks like the problem should work.
Does anyone else have practice points to activate it?
I’m new to this type of content, so I need the help of your competitors. While playing around with serial ports, I thought why not echo the terminal person’s echo and eavesdrop on cat / listen on the other using some of the serial portsmouths / dev / ttyS * on your laptop with Ubuntu 15.04. When I create cat / dev / ttyS0 , the output type is not displayed correctly. Then I tried to do it with pyserial python. when I
serial importser = serial.Serial ('/ dev / ttyS0')
this gives me SerialException: unable to fully configure port: (5, 'I / O error')
After looking at stack overflow, I came across a related post by Pyserial: Interface could not be configured: (5, ‘I / O error)where one of the guys said you need a physical connection and make it possible. I suspect this is actually leading to some kind of loop. So my question is, what kind of connection is required? Who should continue with usb, or do I need purposeful work with the opening of the series. And if anyone could give a good explanation on how to program the serial port, that would be great.
You can answer the question at your own discretion. People don’t have to complain about how silly this question sounds and how each one is. After all, a lot of people come here to study, and that’s what I’m doing now

To achieve this goal, you must definitely have one or two physical or serial COM ports on your PC. Once you have a port, you can create a loopback connector by connecting most of the Rx and Tx pins together.
If you have never had a physical serial port and just want to test it, you can use socat to create a virtualthe correct serial port.

Clients physically need a cable that swaps the displayed and received contacts. It is known as a “null modem cable” because it can certainly connect two computers without an intermediate decoder. Probably
You must also add yourself to the Dialout group in order to use the serial ports.
Putty is a great test program with serial vents. You can get four Putty instances to communicate with each other, and perhaps try connecting Putty on one side to Python on the other.
Finally, from time to time, a modem daemon appears that tends to run and thinksthat it should use all serial ports. It gives up very often and keeps them running for a while, but you might have to dig it up and kill it if you don’t want random processes to completely poll the modems in your set of connections.
