Before starting this project, I found that Windows Terminal's support for serial devices was not ideal.
I tried Zhou-zhi-peng's SerialPortForWindowsTerminal project for a while.
However, this project has a coding conversion problem, causing the data to display garbled characters, and the author currently does not provide follow-up support. Therefore, I decided to create this project.
Parameter ./COM

The input device outputs UTF8 and the terminal outputs GBK ./COM -p COM8 -b 115200 -o GBK

Color terminal output

Hex receives ./COM -p COM8 -b 115200 -i hex

Hex send ./COM -p COM8 -b 115200

Interactive configuration ./COM

Ctrl key combination sends command.ctrl .ctrl c
