5. Click Submit.
6. Repeat above steps as desired, according to additional tunnel(s) available on your product.
Tunnel – Modem Emulation
A tunnel in Connect Mode can be initiated using modem commands incoming from the Serial Line.
This page enables you to configure the modem emulation settings when you select Modem
Emulation as the Tunnel Connect Mode type.The Modem Emulation Command Mode supports the
standard AT command set. For a list of available commands from the serial or Telnet login, enter
AT?. Use ATDT, ATD, and ATDP to establish a connection. All of these commands behave like a
modem. For commands that are valid but not applicable to the EDS1100/2100, an “OK” message
is sent (but the command is silently ignored).
The EDS1100/2100 unit attempts to make a Command Mode connection as per the IP/DNS/port
numbers defined in Connect Mode. It is possible to override the remote address, as well as the
remote port number.
The following table lists and describes the available commands.
