Python serial port turn the terminator off
Multi tool use
I have kinda cheap PLC, which I use to communicate with the data from sensor. I can communicate with PLC by serial UART, and it sends me data without any regular terminator once:
00 f2 c1 c2 fd 12 43
and then waiting for my command, I send the command through the Terminator v1.9 and it sends value back again. I want to write and visualize data with Python, but when I use pyserial with ,e.g., Serial.read(size=1), Python stucks because after receiving 1 byte it waits for CR or another terminator. How can I change this property? I didn't find info about it in regular docs.
