5.0 AT Commands
5.1.2 Telnet (TCP/IP)
Telnet can be used to access the AT Command interface of the IPn3G. The default port is TCP Port 23. A
telnet session can be made to the unit using any Telnet application (Windows Telnet, Tera Term,
ProComm etc). Once communication is established, a login is required to continue.
Image 5-3: Establishing a Telnet Session
The screen capture above shows a telnet request being made to the local NDIS port (USB). A session can
be made to the WAN IP Address (if allowed in the firewall settings) for remote configuration, or to the local
RJ45 interface (default IP: 192.168.0.1).
Once a session is established a login is required to continue. As seen in the Serial port setup, the default
login is
admin
, and the password is
admin.
Once verified, the AT Command Line Interface menu is shown
and AT Commands can now be issued.
