Virtual Serial Port Kit creates pairs of virtual serial ports in your system which are virtually connected to each other. Physical null modem cables are not required. You can connect any number of virtual port pairs. Virtual serial port pairs will look and work exactly like real hardware serial ports connected via null modem cables.Virtual Serial Port Kit is designed for software developer to speed up development process during software debugging

Virtual Serial Port Driver XP (VSPD XP) creates virtual com ports in your system and connects them via reliable virtual link, which emulates real null-modem cable. With VSPD XP you can connect one application to another using virtual serial ports pair. Applications will be able to exchange data. The latest version of VSPD XP now supports full baudrate emulation. New manual and examples are available.

Network Virtual Serial Ports Driver is an advanced utility, the purpose of which is to emulate null-modem cable on computers located in a TCP/IP LAN or connected to the Internet. In other words, with VSPD Net you can create any number of pure virtual serial ports in your system, which will be connected over TCP/IP network to another computer via virtual null-modem cable. Real serial ports will not be occupied.

Share Serial Ports is an advanced utility for sharing real serial ports between multiple applications so that all applications will receive same data from real serial port simultaneously. It is achieved by creating virtual serial ports, exact copies of real ones. All virtual ports can send data to real serial port. You will be able to set port permissions to read, write or change control lines state for every application separately.
