AT command support is pretty straightforward since it works with ASCII strings. I would focus on finding a good library supporting serial port operations for whatever platform you are on.
Now if you have to support X,Y, or Z-modem…, or something like that, that’s a different challenge.

Subject: Want some advice on how to implement ATcommand handling with Lua.
I have to implement a SW that does ATcommand communication with a modem.
The modem is LTE or 5G modem.
I know there are a few serial communication apis in lua world.
Is there any open source lua program that implement AT command?
Thank you in advance!
