Is it possible to re-assign the UART pins during runtime to connect to another peripheral? For example:

//connect to primary external peripheral device
Serial1.setRX(1);
Serial1.setTX(0);
Serial1.begin(9600);
//talk to primary peripheral device
//end and connect to secondary external peripheral
Serial1.end()
Serial1.setRX(13);
Serial1.setTX(12);
Serial1.begin(9600);
//talk to 2nd peripheral device

Is something like this supposed to work?

(BTW Thank you for the excellent arduino port!!)
