Its python3, im trying a lot of codes from forums, sending ASCII messages true socket inside camera, im getting replyes like Log in after sending login and password:  
Socket Created  
Socket Connected to example\_ip on ip example\_ip port 23  
Username:  
Password:  
Login succeeded

but when im sending another comand im heting 25 thousand of ascii, when its not similar with dimensions to image.

I tried [[Solved] Connecting Cognex to Halcon - Technical questions - RobotExchange](https://www.robotexchange.io/t/solved-connecting-cognex-to-halcon/146) -- python 3 code, but when im sending img like comand i cant get image.

I tried rewrite this code: [Getting 1MB of ASCII Cognex image with Java sockets and TCP ZeroWindow issue](https://forum.inductiveautomation.com/t/getting-1mb-of-ascii-cognex-image-with-java-sockets-and-tcp-zerowindow-issue/56966) to python but also without effect
