Demonstrates the Chilkat Socket ReceiveByte and SendByte method.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Socket sock = new Chilkat.Socket();

// --------------------------------------------------------------------
// This example uses the public TCP echo service at https://tcpbin.com/
// --------------------------------------------------------------------

bool useTls = false;
int port = 4242;
int maxWaitMs = 5000;
bool success = sock.Connect("tcpbin.com",port,useTls,maxWaitMs);
if (success == false) {
    Debug.WriteLine(sock.LastErrorText);
    return;
}

// Wait a max of 2 seconds for a response..
sock.MaxReadIdleMs = 2000;

// Send a byte.
sock.SendByte(96);

// The tcpbin.com echo server only echoes after receiving an LF (linefeed char)
sock.SendByte(10);

// The echo server will echo back whatever is sent to it.
// We should be able to read the same byte back..
// After successfully reading, the byte value is available in the ReceivedInt property.
bool treatAsUnsignedInt = true;
success = sock.ReceiveByte(treatAsUnsignedInt);
if (success == false) {
    Debug.WriteLine(sock.LastErrorText);
    return;
}

// Let's look at the value of the byte received.  It should be 96.
Debug.WriteLine(Convert.ToString(sock.ReceivedInt));

// The echo server also echoed the LF back.
success = sock.ReceiveByte(treatAsUnsignedInt);
// Assuming success..

// Should be decimal 10.
Debug.WriteLine(Convert.ToString(sock.ReceivedInt));
