Arduino Ethernet - client.remotePort()用法及代码示例

client.remotePort()

#include <Ethernet.h>
#include <SPI.h>

byte mac[] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};
IPAddress ip(10, 0, 0, 177);

// telnet defaults to port 23
EthernetServer server = EthernetServer(23);

void setup() {
  // Open serial communications and wait for port to open:
  Serial.begin(9600);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }

  // initialize the Ethernet device
  Ethernet.begin(mac, ip);

  // start listening for clients
  server.begin();
}

void loop() {
  // if an incoming client connects, there will be bytes available to read:
  EthernetClient client = server.available();
  if (client) {
    Serial.print("Remote port: ");
    Serial.println(client.remotePort());
    client.stop();
  }
}
