# TELNET > [HTML Version](telnet_lit.htm) _Updated May 2014; see History_ **TELNET \{switches\}** (Windows only) TELNET launches ATE (the A-Shell Terminal Emulator) to establish a session with the specified configuration. The configuration name must have been previously defined using [ATECFG](atecfg_lit.htm.md) (which see) or with the /E switch. You can terminate the session either from the remote host (i.e. by logging out) or by entering |d (vertical bar, D). TELNET also supports an ATEAUTH.SBX hook, allowing you to preconfigure aspects of the connection properties before the dialog is displayed or the connection takes place. If ATEAUTH.SBX exists in the %MIAME%\\DSK0\\007006 directory, it will be called via ATEAUTH.SBX; see bottom of this page for details. **Switches** | **Switch** | **Function** | |------|------| | (none) | Write switch listing and usage info to the screen. | | /E | Edit configuration. | | /F | Auto-accept host fingerprint (SSH mode). | | /I | Select configuration interactively. | | /V | Verbose mode. | | /? | Write switch listing and usage info to the screen. | **Comments** TELNET uses AG\_WINSETTINGS to reload the window settings after you select a connection profile, allowing the previously saved settings from that connection to be restored. **ATEAUTH.SBX** **xcall ATEAUTH, connection'name, status** **Parameters** _connection'name_ ([String](string.htm.md)) \[in\] is the name of the connection configuration. _status_ ([Num](num.htm.md)) \[out\] may be set to a non-zero value by the SBX to abort the connection. It is pre-cleared, so the SBX doesn't need to update it unless it wants to abort.
