When a peripheral seems to return whatever you send to it, that usually means your cabling is faulty, e.g. you forgot to connect the voltage reference ("ground"), or you switched data in and data out wires.

Suggestion: get your hardware in working order before investing in software.
Things that may help:
1. write a simple (I repeat: simple) program that just sends a command periodically, at best something your peripheral should react on with some visual feedback (e.g. blinking a LED).
Best: add some LEDs to your peripheral and implement one-byte commands to turn them on/off.
("observability is the key to success")
2. alternatively: do whatever it takes to make your peripheral send known data, and capture that with a (virtual) terminal.
3. do make sure your serial port parameters (baud rate, parity, stop bits,...) are identical on both sides.

As long as neither 1 or 2 works, your hardware connection is not good.

PS: NEVER write software that swallows exceptions; they exist to tell you what goes wrong where; ignoring them (or reducing them to error=true) is a criminal offence.

The Windows 11 "taskbar" is disgusting. It should be at the left of the screen, with real icons, with text, progress, etc. They downgraded my developer PC to a bloody iPhone.
