title: PySerial - Max baud rate for platform (windows)
body: <p>I'm trying to get pySerial to communicate with a microcontroller over an FTDI lead at a baud rate of 500,000. I know my microcontroller and FTDI lead can both handle it as can my laptop itself, as I can send to a putty terminal at that baud no problem. However I don't get anything when I try to send stuff to my python script with pySerial, although the same python code works with a lower baud rate.</p>
  
  <p>The pySerial documentation says:</p>
  
  <p>"The parameter baudrate can be one of the standard values: 50, 75, 110, 134, 150, 200, 300, 600, 1200, 1800, 2400, 4800, 9600, 19200, 38400, 57600, 115200. These are well supported on all platforms.</p>
  
  <p>Standard values above 115200, such as: 230400, 460800, 500000, 576000, 921600, 1000000, 1152000, 1500000, 2000000, 2500000, 3000000, 3500000, 4000000 also work on many platforms and devices."</p>
  
  <p>So, I'm assuming why it's not working is because my system doesn't support it, but how do I check what values my system supports/is there anything I can do to make it work? I unfortunately do need to transmit at least 250,000 and at a nice round number like 250,000 or 500000 (to do with clock error on the microcontroller).</p>
  
  <p>Thanks in advance for your help!</p>
