1. Serial Port Emulator

Virtual Serial Port Emulator creates virtual ports and allows to use them like real. This program efficiently emulate. Free Virtual Serial Ports is a Windows user-mode application, which allows you to create software virtual serial ports and emulate physical serial ports behavior. It operates exclusively in user-mode, therefore it is more stable and uses less memory, processor and operating system resources than any competitive products.

I'm about to start developing a small app (C#) that communicates with a PLC and a testing unit via Serial Ports - this is my first venture into this area. In essence, I am going to send the PLC a signal to start an operation, and then I am going to wait for the result of that operation from the test unit (which will be independently communicating with the PLC) to return a ASCII string.

Depending on the content of that string, I may want to listen to a signal from the PLC. It's all new to me, so at the moment, I'm just researching System.IO.Ports.SerialPort; digression: are there third part products out there than simplify interaction with the Serial Port, or are the built-in classes as good as you will get? I'm thinking of ease of use as opposed to better features. Toni braxton getting married to birdman. However, it will be a few weeks before the hardware is available for development and testing, so I was wondering how I could simulate communication to/from the serial port so that I can start developing my app? [I don't yet know how the PLC and the PC are due to communicate - I understand it will be binary rather than text, but at the moment, that is all I know.]. There are two pieces of software that I have found invaluable while doing serial port work.
