tkterm VS pySerial

I am working on something similar. I encourage you to take a look at https://github.com/axs5489/tkterm You want the tkterm.py and tksetup.py files. Its far from complete, but I figure I'd save you some time. Serial uses a menu system to pop-up various settings windows, returning them to the main window. I wanted the ability to pop up multiple instances of Serial and have them not interfere with each other (closing the first one used to close all). I fixed that by instantiating a master windowing class (minimized via the withdraw command), automatically instantiating a Serial object and having the ability to add/remove them. My current problem is getting the master window to close when its run out of child windows.

Code your REST endpoint to use something like pySerial to send the message to your device

If the Tach is the older style I think this would be a great first project. If you need to emulate CAN it’s going to be a rather more complex project. python CPU/RAM utilizationpython Serial communication library

I haven't, but I would try a Linux box with two serial ports, connect both things to it so it's literally man in the middle. The PySerial module for Python, and it has an example bi-directional Serial to TCP/IP relay including a threaded serial listener, you might be able to hack that into a Serial <--> Serial relay with custom logging/interception fairly quickly.

Connecting to the Russound device is only possible by TCP, you can make use of a TCP to Serial gateway such as tcp_serial_redirect

Look in source https://github.com/pyserial/pyserial/blob/master/serial/serialcli.py

The code that runs on the Raspberry Pi needs to listen for incoming data over the serial connection. Several libraries exist, we will choose the Python library pyserial.

Try pyserial
