How do you simulate a serial device?

Question

I am working on a driver that talks to a device through a serial port in C #. My device for physical testing is not always available. Is there a way to simulate a device on a serial port so that it responds perfectly?

Answer 1

Get a second COM port and use a Null-modem cable to connect the COM ports to allow two C # programs to talk to each other.

Answer 2

I used Com0Com for a while and wrote simulator / emulator code.
