Microhard Systems IPN3G - Telnet (TCP;IP) Interface

© Microhard Systems Inc. 131
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.
