How SLNet Works

SLNet software runs on a Windows server and allows multiple devices to connect to telnet sessions up to the amount of the SLNet license.

  • SLNet seamlessly creates unique connections to your applications by running multiple copies of its SLCon executable that talks directly to your application.
  • Mobile devices can receive menus to choose applications or servers.
  • SLNet automatically reconnects devices that disconnects when they come back in range.
