/*
Serial Event example
When new serial data arrives, this sketch adds it to a String.
When a newline is received, the loop prints the string and
clears it.
A good test for this is to try it with a GPS receiver
that sends out NMEA 0183 sentences.

/*
Twitter Client with Strings
This sketch connects to Twitter using an Ethernet shield. It parses the XML
returned, and looks for <text>this is a tweet</text>
You can use the Arduino Ethernet shield, or the Adafruit Ethernet shield,
either one will work, as long as it's got a Wiznet Ethernet module on board.
This example uses the DHCP routines in the Ethernet library which is part of the
Arduino core from version 1.0 beta 1
This example uses the String library, which is part of the Arduino core from
version 0019.

Software serial multple serial test
Receives from the two software serial ports,
sends to the hardware serial port.
In order to listen on a software port, you call port.listen().
When using two software serial ports, you have to switch ports
by listen()ing on each one in turn. Pick a logical time to switch
ports, like the end of an expected transmission, or when the
buffer is empty. This example switches ports when there is nothing
more to read from a port
The circuit:
Two devices which communicate serially are needed.
* First serial device's TX attached to digital pin 2, RX to pin 3
* Second serial device's TX attached to digital pin 4, RX to pin 5
