Virtual Serial Port Kit

http://www.virtual-serial-port.com http://www.virtual-serial-port.com

Virtual Serial Port Kit allows creating a pair of virtual serial ports connected with virtual null-modem cable. The software provides null-modem connection between two serial communications applications. Communications software interacts with each other via virtual COM-ports in the same way as via hardware COM-ports connected with null-modem cables.

  • Allows to create virtual serial loopback plugs
  • Full hardware serial ports emulation
  • Virtual serial ports look and work like real hardware ports
  • Serial data bitrate (transmission speed) emulation
  • Different virtual null-modem schemes are available (full, partial, loopback)
  • Unlimited number of virtual COM port pairs can be created
  • Once created virtual ports are operable at each system startup (prior to user login)
  • Overlapped virtual COM ports support (virtual serial ports can have the same names as existing physical COM ports)
  • Real null-modem cables are not required
  • Real serial ports are not occupied
  • Virtual communication is more fast and reliable than via real null modem cable


  • 64bit and 32bit compatible
  • Full Microsoft serial.sys compatibility
  • PnP and WMI technologies compatibility
  • Hyper-Threading Technology compatibility
  • VMware compatibility
