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:

+++	Switches to command mode if entered from serial port during
	connection.
AT?	Help.
ATDT<Address Info>	Establishes the TCP connection to socket (<IP>/<port>).
ATDP<Address Info>	See ATDT.
ATD	Like ATDT. Dials default connect mode remote address and
	port.
ATO	Switches to data mode if connection still exists. Vice versa to
	'+++'.
ATEn	Switches echo in command mode (off - 0, on - 1).
ATH	Disconnects the network session.
ATI	Displays modem information.
ATS0 = n	Accept incoming connection. (n = 0: disable, n = 1: connect
	automatically, n = 2+: connect with ATA command (basically
	wait for the user or application to issue a command to "pick up
	the phone")
ATQn	Quiet mode (0 - enable results code, 1 - disable result codes)
ATVn	Verbose mode (0 - numeric result codes, 1 - text result codes)
ATZ	Restores the current state from the setup settings.
A/	Repeat last valid command.

These commands allow the EDS to emulate a modem. The EDS ignores valid AT commands that do not apply to the EDS and sends an OK response code.

In Command mode, the EDS can make a connection to the remote host and using the remote address and remote port information specified on the Tunnel – Connect Mode page (see Tunnel – Connect Mode Page on page 63).

When making a connection from the EDS using an ATDT or ATDP command, full or partial IP addresses can be used. If a partial IP address is used, the EDS 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 EDS to connect to the IP address and remote port configured in Connect Mode.

‹Entering ATDT 119.25.50 causes the EDS to assume the first octet in the IP address and connects to the remote IP address 192.119.25.50, port 10001.
