#### Example

    #include <Ethernet.h>

    byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
    byte ip[] = { 10, 0, 0, 177 };
    byte server[] = { 64, 233, 187, 99 }; // Google

    Client client(server, 80);

    void setup()
    {
      Ethernet.begin(mac, ip);
      Serial.begin(9600);

      delay(1000);

      Serial.println("connecting...");

      if (client.connect()) {
        Serial.println("connected");
        client.println("GET /search?q=arduino HTTP/1.0");
        client.println();
      } else {
        Serial.println("connection failed");
      }
    }

    void loop()
    {
      if (client.available()) {
        char c = client.read();
        Serial.print(c);
      }

      if (!client.connected()) {
        Serial.println();
        Serial.println("disconnecting.");
        client.stop();
        for(;;)
          ;
