getty | netty like asynchronous network I/O library | Websocket library

First i am a lost noob

I have been recently trying to find out a way weather i can send serial data (large file like image data) only through the Rpi w 0's micro USB port using ttyGS0.but when i searched online i only found ways of setting up headless through serial and other stuff which was no what i wanted. But i did follow the tutorial half way

• I went to '/boot/config.txt' and set 'dtoverlay=dwc2' at the end of the file after leaving a line

• I went to '/boot/cmdline.txt' and did put 'modules-load=dwc2,g_serial' after 'rootwait' leaving a space

Thinking i could just use the /dev/ttyGS0 in my serial program on the Rpi and send the data the data was being sent but on my PC when i tried to access my Rpi which was on comport 12 it said port not found and couldn't open it.But it was showing up in the device manager as 'PI USB to Serial(COM12)'

Then i wondered weather it would be possible at all to access Rpi's comport this way.

If that's the case, i want to know if there is any other way to access the Rpi's USB port only using the USB cable

Note:-

• I don't want to use Rpi's USB as a way of loging ie. 'headless setup'.i just want to receive serial data like an arduino.
• I don't want to use the GPIO pins(i tried) as they can only send limited characters at a time and i want to send an image file. Very quickly.
• I don't have any serial converters at hand so i could route it to the arduino and use /dev/ttyUSB0 then read it on PC. I just only want to use the USB cable.
• In case this info is required:-
  • my pc is a probook 6560b running windows 7

things i found while testing and stuff:-

• I did do -lsusb command but i dint find my device on that list
• I tried the 'ls /dev/ttyGS0' and i found '/dev/ttyGS0'
• I checked many forums and some guys were asiking to use this command 'dmesg | grep tty'and show them the code . So i performed it i dont understand what alot in the piece of text means but if it would be helpfull i pasted it here:-

I want to get the count of country records in a multidimensional array. I also would like to get the same count, but filtered by the record, so count of the Netherlands.

I've tried this:

I'm new to python and I'm trying to use the census geocoding services API to geocode addresses then convert the output to a dataframe. I've been able to read in my address file and I can see the output, but I can't seem to figure out how to import it into a dataframe. I provided the code I used below as well as the contents of the address file.

The output does not appear to be in JSON format, but rather CSV. I tried to import the output as I would a CSV file, but I couldn't figure out how to import the variable as I would a CSV file and I couldn't figure out how to export the output to a CSV file that I could import.

The URL describing the API is https://geocoding.geo.census.gov/geocode...es_API.pdf

I have a VM instance that I'm trying to access from Notebook AI. It's been functional for about 2 months, but when I tried to start it today it gets hung up on "Setting up proxy to JupyterLab." It's been stuck on that for about 30min and I also can't SSH in to see what's going on. Any thoughts?

Edit: this is what I see in serial port log 1

Yesterday we lost contact with 10 identically configured servers, after some investigation the conclusion was that a reboot after security updates had failed.

We have so far not been able to get any of the servers back online, but were lucky enough to be able to reinstall the instances without data loss.

I will paste the console log below, can anyone help me determine the root cause and perhaps give me some advice on if there is a better way to configure the server to make recovery easier (like getting past the "Press Enter to continue." prompt, that it seems to hang in).

The full log is too big for SO, so I put it on pastebin and pasted a redacted version below. I have removed the escape sequences that colorize the output and removed some double new lines, but besides that it is complete.

I'm writing a beginner program that takes a text file of 10 trivia questions and answers, reads the file, puts the questions and answers into an array, and then uses the questions for a trivia game.

Currently, I'm having an issue reading the file into the array. Only the first line of the file is being read.

I'm new to debugging, but I tried to rewrite the program with Vectors and had the same issue.

Here is the trivia file (the number at the end of the answers is the correct answer):

The command '(sleep 4 ; echo q) | topas -P |tee /tmp/top' on AIX produces this output in a command text file and I am not able to remove the blank spaces from it. I have tried, sed/perl and awk commands to print only the lines containing characters however nothing has helped. Do I need to convert this file to a ASCII text format to use sed/per/grep or awk to remove the empty lines?.

I have the problem that my queries occasionally fail to insert/update, however, no error is thrown in the python script or the database log.

Here is the detailed explanation:

Changes I made to my.cnf of MySQL Server without resolving the problem.

Backstory: I recently got a Raspberry Pi 4 Model B and a Protoneer RPI CNC Hat, which it controls via the serial port (/dev/ttyAMA0). After I put it all together and it didn't work at all (either in Minicom or bCNC), I've been gradually trying to zero in on the source of the problem. My oscilloscope shows that I can control the relevant pins when using them as GPIOs, so I do not suspect a fundamental hardware problem. However, I am completely unable to provoke a response from the pins when using them as a serial port. I have written the below C program to characterize the issue as exactly as possible.

Problem: I have a serial port, /dev/ttyAMA0, and it doesn't work.
