Start up baud rate always 115200

[usernameisdarian]

I use 1000000 or 2000000 baud in the serial monitor. Set in the "vscode-serial-monitor.customBaudRates"

I use for Programming a STMG0B via the Arduino compiler.

During programming the serial monitor disconnects then reconnects as needed during the program but when it reconnects it always reconnects at 115200 Baud not the 1000000 baud that was set when it disconnected.

I have this same problem. I have my serial set to 9600 baud, but every time I upload a sketch to my Arduino Nano the serial monitor resets to 115200 baud and also changes the line endings from CRLF back to None.

@JamesMessinger @usernameisdarian Thanks for the issue! This issue actually belongs on the arduino extension. The reason is because the Arduino extension has its own mechanism for selecting a baud rate, and it is not aware of the Serial Monitor extension having custom baud rates. It instead relies on its own knowledge of selected baud rates. To make this better, the best solution would be to allow the arduino extension to see into the customBaudRates setting in VS Code, that way you can select it from the arduino extension and then restoration should work. Thanks!
