Question
I have a c# app that connects pc to a device, through a serial port.
When I send data to the device, if the device sends data back, the datareceived event fires.
And I want to ask this. Is there a way to simulate the data sending of the device?
I mean, i want to fire datareceived event not only when the device send data.
Is this possible?
Solution
You must have an additional free serial port.
If need be, you may:
- just add another new one or
- install a virtual COM port solution (such as com0com).
You can harness your C# program using a software emulator of the device through Null modem.
