Size of uart buffers

Hi Pyt, The internal buffer size is just the size used to transfer serial data close to the hardware level. You should be able to send as much data as you'd like. Chris Go to the full post

What are the sizes of the UART buffers on the Netduino Plus 2 ? After a little search and experimenting, I figured the receive buffer is 512 bytes and the send buffer 256 bytes. Is this right ? Is this documented anywhere ?

Will the SerialPort.Write() method properly work if used with a buffer larger than the size of the send buffer ?

Thanks,

Pyt.
