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.
Any idea how?
Thanks
I have used com0com tool for this. It has no direct API, but you can write an application (or a method) which starts a new com0com process to set up / modify your virtual ports “on the fly” with commandline parameters.
