Faking an RS232 Serial Port

Question

I'm developing a project that has a number of hardware sensors connecting to the deployment machine through RS232 serial ports.

But ... I'm developing on a machine without an physical RS232 serial ports, but I would like to make fake serial ports that I can connect to and output data from with the aim of faking input from hardware sensors.

Does anyone know of a way to create a fake serial port and control it on Windows XP?

Answer 1

If you are developing for Windows, the com0com project might be, what you are looking for.

It provides pairs of virtual COM ports that are linked via a nullmodem connetion. You can then use your favorite terminal application or whatever you like to send data to one COM port and recieve from the other one.
