-/** A serial port (UART) for communication with other devices using  
- * Half-Duplex, allowing transmit and receive on a single
- * shared transmit and receive line. Only one end should be transmitting 
- * at a time.
- * 
- * Both the tx and rx pin should be defined, and wired together. 
- * This is in addition to them being wired to the other serial 
- * device to allow both read and write functions to operate.
- *
- *  For Simplex and Full-Duplex Serial communication, see Serial()
- *
- *  Example:
- * @code
- * // Send a byte to a second HalfDuplex device, and read the response
- * 
- * #include "mbed.h"
- * 
- * // p9 and p10 should be wired together to form "a"
- * // p28 and p27 should be wired together to form "b"
- * // p9/p10 should be wired to p28/p27 as the Half Duplex connection
- *
- * SerialHalfDuplex a(p9, p10);
- * SerialHalfDuplex b(p28, p27);
- *
- * void b_rx() { // second device response
- *     b.putc(b.getc() + 4);
- * }
- *   
- * int main() {
- *     b.attach(&b_rx);
- *     for (int c = 'A'; c < 'Z'; c++) {
- *         a.putc(c);
- *         printf("sent [%c]\n", c);
- *         wait(0.5);   // b should respond
- *         if (a.readable()) {
- *             printf("received [%c]\n", a.getc());
- *         }
- *     }
- * }
