Create Virtual Serial Port C#

Faking an RS232 Serial Port I have an application that reads data from serial port. To test the application i would like to create a virtual serial port that generates data and puts the the port at the same PC, so that the other app can access that data.

A question for the vb.net GURU(s) out there. Is there a way I can create a virtual serial port in vb.net in code.

Basically I want to be able to read what is being written to a com port (which will be the virtual port) reformat what is being written and send it out another com port. This is of course without buying external software or using a driver for this.

I've been searching around alot over the internet but could only find external software to do this. Has anyone done this before? Thanks in advance. The loopback is possible but the only issue is that you will still need to use another serial port to send the reformatted information to another device. Which means two com ports are used instead of just one.

Com1 transmits to com2, com2 transmits to device. But unfortunately the plan was to read data being sent out one com port (the virtual port that I'm wanting to learn how to create). Read the data being sent out the virtual port(this may need looping back).

Reformat the data and send the reformatted data out a physical com port. If this is possible then I will be able to use only one com port.

What do you need to simulate? The communication with an external device which is not present during the tests?

- First find out which functions and properties of SerialPort you really need (in our case, we just needed a few of them). - Create an interface defining them. - Create a wrapper for the 'real' port which implements your interface. That will be the instance used in production.

- Make your other code depend on your interface instead of the 'real' port. - Create a dummy port which implements your interface, and add the logic for emulating the device. That's the instance used for testing.

- You may create further dummies which simulate communication problems - now you can test that your code copes with that, too.
