Netduino maximum baud rate is 3000000 bps (48 MHz divided by 16 for 16× oversampling*). The question is at what speed the managed code will not be fast enough to consume received data - so let us know your findings.Update: After a few experiments, I managed to get the serial device and Netduino to communicate at 230400bps. I will try for 460800bps next and let you guys know if it works out.
* It could be doubled at 8× oversampling, but this would require change in firmware to modify values set during UART initialization, or to provide additional properties to the object model.

COM1 or COM2? COM1 has some limitations if I'm correct.i can only get a max of 115200 without my np going tits up!

20kByte = 163840 bit. Devided by 10 seconds = 16384bps.something is not quite right for some reason its taking nearly 10secs to transfer a 20k jpeg image @ 115200!
So it's not reaching it's full potential indeed.
Tried both COM ports?

I know this is for the regular netduino, but just wanted to report I'm getting speeds via both, COM1 and COM2 on the Neduino + 2 at 2Mbaud.
