Hi to all, i'm quite new to Arduino world. I'd like to know what is the max speed allowed by the arduino UNO serial port and what is the size of the buffer. I would like to send command from my pc at 115200, is it possible?
Yes, it's possible - the documentation for serial.begin has 115200 as an example - not sure that that is necessarily the top speed of Arduino, or just the fastest option that's commonly offered in PC terminal programs. Buffer is 128 bytes

I used 230.400 and 345.600 baud several times with succes, even test with 500.000 with no failures. On the PC side I used putty.exe to capture the output as the serial monitor in the IDE could not handle this speed. See - http://arduino.cc/forum/index.php/topic,61381.0.html -
Thank you both for the fast reply!
I am already playing with serial port, some experiment and then i'm gonna try to communicate with my program!
