  • Dynamic port redirection support (Including X11)
  • IPv6 Support
  • Access to local serial ports - COM

  • Allows you to save the session to file
  • Allows you to save the session configuration
  • Small size (512K) and transportable

It is a simple but complete remote access tool.

Not having a simple way to manage the sessions there are tools like WinSCP that allows to help in this management.

To finish and because it does not seem intuitive to access the settings after a session has been established you should use the right mouse button at the top of the window. This way is exposed the menu that has numerous options.
