serial port is placed in Command Mode by issuing the modem command +++.

Command Mode

The Modem Emulation's 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:
+++
AT?
ATDT<Address Info>
ATDP<Address Info>
ATD
ATO
ATEn
ATH
ATI
ATS0 = n
ATQn
ATVn
ATZ
A/
These commands allow the IntelliBox to emulate a modem. The IntelliBox ignores valid
AT commands that do not apply to the IntelliBox and sends an OK response code.
In Command Mode, the IntelliBox can make a connection to the remote host using the
remote address and remote port information specified on the Tunnel – Connect Mode
page.
When making a connection from the IntelliBox using an ATDT or ATDP command, full or
partial IP addresses can be used. If a partial IP address is used, the IntelliBox uses the
remote address and port as configured in the Connect Mode settings.
For the following examples, we assume that the remote address is 192.168.16.10 and
the port is set to 10001 in the Connect Mode settings:
 Entering ATDT alone causes the IntelliBox to connect to the IP address and remote
port configured in Connect Mode.
