The method in Python takes a single large string as input, which can also be considered as an iterable of strings. Instead of passing in individual lines, you can use a generator expression to send in lines with added newline. By creating a generator that yields cleaned lines, you can eff...

While connecting to a “remote” device or using a serial port introduces inherent delays, separating the code into different threads ensures better performance overall. I have tested these changes on macOS and Linux, but Windows—especially the MSVC build of Serial Studio—has not been tested ...
Using this on a Ubuntu linux system (14.04) I found that I got the following exception while writing to the serial port. This would imply that the write is not correctly set to non blocking in the posix serial transport. I'll continue to debug this issue. protocol: <__main__.Serial...

Hi: I'm using pySerial to talk to a RS232 to RS485 converter. In order to control the converter, I need to control the DTR line to enable/disable de RS485 driver. In particular, I need to : write a character to the serial port set the DTR line to level
