StarNet's X-Win32 and FastX product lines are X Windows Emulators (also known as PC X Servers or X11 emulators). Engineers typically work on Windows or Macintosh PCs while the applications they use to design anything from an advanced microprocessor to an Air Force Jet reside on powerful Unix and Linux mainframes and supercomputers. In order to access those applications, they need a PC X server. X-Win32 and FastX connect the workstation to the remote servers in order to display those applications onto the workstation desktop.
