The Mono framework's SerialPort class does not support the ''DataReceived'' event, so it may be necessary poll the serial port to receive data, or use one of the following potential workarounds:

• Mono SerialPort.DataReceived Event Workaround – Using a Derived Class
  • Download a Visual Studio solution that implements this workaround
• If you *must* use .NET System.IO.Ports.SerialPort
• Use the RJCP.DLL.SerialPortStream library, an independent serial port implementation.

The following example implements a client and a server. Server.exe runs on a Windows PC, and Client.exe runs on the ComfilePi. When the commands date or time are typed into the client, the server responds with the date and time respectively.
