Title: Maximum baud rate is 460800?
Post by: randomrichard on May 23, 2013, 05:17:19 am

Hello
I have a fast 16bit ADC using the Arduino Due that can send at 921600 baud. However, none of the terminals I have tried will go faster than 460800 baud, including COMPortTerminal, after the bit rates available are suitably modified. It will do 460800 (http://) but not 921600 or intermediate values. Does anyone know if this is a Windows restriction, or what?

Baud rates must be supported by the port hardware and the software driver used to access the port.

One way to get fast baud rates is by using a USB/serial converter:
