Eltima's Virtual Serial Port Driver generates COM port pairs within the system, facilitating communication between serial applications through virtual null-modems for effortless data transfer.

With the help of these virtual ports, serial applications can transfer data between each other as well as communicate via a virtual null-modem cable. Furthermore, efficient emulation of strict baud rates, HandFlow control and signal lines also makes this virtual serial port driver a highly efficient one.
After users create a virtual COM port pair using VSPD, they can easily view the newly created virtual ports in the device manager. These ports are automatically available during system start-up, even prior to logon, making VSPD an extremely user-friendly software.
Virtual Serial Port Driver comes in two forms: a GUI version and a driver version along with API. The latter is specifically aimed at those who wish to integrate the software into their own product. Overall, VSPD is an indispensable tool for people dealing with serial applications and virtual ports.
