I am stuck with below mentioned problem.

  1. Application 1(c#) on machine is communicating with device1 over physical serial port (RS232).Application 1 sends the command and device 1 sends the response over serial port. 2.I want to read the response from device in another application2 (in c#) at the same time when application 1 is listening on serial port.

Application 1 is already implemented in c# and i need to create application 2 in c#.

Please let me know how I can read the response from device in application 2 over same serial port.

Thank you so much in advance :)

  • You can't open the same com port twice. The only thing I can think about is that your first application share the data read with your second app. – Pikoh Mar 08 '17 at 11:00
  • Thanks for the quick response Pikoh. but i am very new to this area.Can you please help me to know the details or mechanism by which my first application can share the data with application 2. – ruchi verma Mar 08 '17 at 11:02

    Try to make virtual COM port and connect first app to this and spy application by pass data from port to virtual port. – CrazyBaran Mar 08 '17 at 12:45
  • How does serial port sniffing tools (Docklight or device monitoring studio) monitors the data at the same comport which is already in use? – ruchi verma Mar 09 '17 at 05:47
