Virtual Serial Ports Emulator

Virtual Serial Ports Emulator (VSPE) is a tool to help engineers and developers to create/debug/test applications that use serial ports. It can create virtual devices to transmit/receive data. Unlike regular serial ports, virtual devices have special capabilities: for example, the same device can be opened more than once by different applications, that can be useful in many cases. With VSPE you are able to share physical serial port data for several applications, expose serial port to local network (via TCP protocol), create virtual serial port device pairs and so on.
