Description   The Wiring serial library allows for easily reading and writing data to external machines. The serial port is a nine pin I/O port that exists on most PCs and can be emulated through USB on Macintosh with the Keyspan USB Serial Adaptor. The begin(rate) method must be placed in the setup() method.
