TCPIP Sample

This sample includes a simplified TCP server, a simplified blocking TCP client, and a simplified non-blocking TCP client.

• A client connects to a server, sends one packet, receives an echoed packet, and then closes the connection.
• The server accepts a connection from a client and echoes received packets back to the client. It terminates when the connection is closed.
• A non-blocking TCP client sample demonstrates how to connect a non-blocking client to a server for the TCP/IP Stack, which differs from Windows.

Running the Sample

Rtssrun TCPIPServer.rtss

Note: This sample will choose the first interface IP. If you are using the Virtual Network, and you want to use an actual Network Interface Card for this sample, disable the Virtual NIC.

Rtssrun TCPIPClient.rtss <server IP Address>

Output

The output of TCPIPServer should look like this:

*** TCPIPServer: WinSock started ***

Bytes received: 13

Bytes sent: 13

Connection closing...

The output of TCPIPClient and TCPIPClientNblock should look like this:

*** TCPIPClient: WinSock started ***

Bytes Sent: 13

Bytes received: 13

Connection closed
