title: How to change default baud rate of serial monitor in VSCode with PlatformIO?
body: <p>I have VSCode and PlatformIO plugin.
  When I start serial monitor it always starts with 9600 baud rate. I'd like to change that, so it always starts with 115200.</p>
  
  <p>I can change the baud rate of already running serial monitor by pressing CTRL+T, b, 115200, enter but I don't want to do this every time I start my serial monitor.</p>
  
  <p>I can't find that setting anywhere. I tried adding a line <code>speed = 115200</code> to platformio.ini but that didn't change anything.</p>
