Virtual Serial Port Control 3.0.3

Create and control virtual COM ports to which any serial application can connect.

Virtual Serial Port Control is powerful component which makes it possible to create virtual serial ports and control them fully. At the same time virtual ports look like as if they were real hardware serial ports for communications applications. It is believed that communications applications are intended to work only with hardware serial devices connected to physical serial ports.

VSPC allows you to create additional virtual serial ports directly from your own program. And any communications application can work with them as if they were physical ports. On the other hand, developers API provided by VSPC allows your program to access the data written to virtual serial port by communications application and it also allows responding with your own data. The data will be read by the communications application from the virtual serial port as if it were read from a physical port.

VSPC provides a developer with full control over virtual serial port. VSPC + virtual serial port can as much as a serial device + a physical serial port. Moreover, VSPC drives virtual serial port the same way as a serial device drives a physical serial port.
