Is there a method to flush the serial port and clear all of the data from the buffer?

No, but good idea. I'll look to add that.

The last one should be:

LPC_UART0->FCR |= 0x06;

A simple (and crude) method that works for me:

void flushSerialBuffer(void) { char char1 = 0; while (device.readable()) { char1 = device.getc(); } return; }

Thank you, this is absolutely necessary everywhere in serial communication!
