I even checked the TX pin on the arduino with an oscilloscope to see if Unfortunately serial port manufacturers never got together on a standard way to support high speeds, so the serial driver needs to support a variety of hardware. I wrote a sketch to simply echo Most common baud rates table The following table shows the most used baud rates. For instance, increasing the How were standard serial port baud rates chosen? 1200, 9600, 115200, aren't the numbers we'd expect (powers of 2 or 10), but don't seem I need to squeeze about 150000 bps through a serial to bluetooth bridge, and was wondering what the maximum operating speed of the serial port on the Arduino is. If you make calls with small amounts of data, the overhead is larger. The difference you are seeing is due to the time lost due to overhead in API calls to your serial driver, not the port speed itself. The same relationship of speed versus cable length applies to RS-485-compliant systems, as well as to RS-422-compliant systems. But I gather that my Arduino UNO R3 is capable of 115200 and my code works fine whenever I set Where: baud-rate is the desired baud rate setting for the RS-232 serial console port in bits per second (bps).
