As soon as someone types an AT command, the MSS will enter modem mode and begin processing the AT commands.

Modem Mode Commands

The following commands are available only in modem mode—they will have no effect when typed at the Local> prompt.

	Figure 5-18: Modem Mode Commands
	Command		Function
	AT?	Help; gives list of valid AT commands.
	ATC <command>	Pass-through to normal command line interface.
		Ex: ATC CH SERVER NAMESERV 192.168.0.10
		Forms a TCP connection to the specified host. Two IP address formats are
		allowed. The first uses periods, while the second omits periods and adds
		zeroes to segments less than 3 characters long:
		Ex: ATDT 192.168.0.10:3001T
	ATDT <ipaddress>	Ex: ATDT 192.168.00.010:3001T
		Users can specify sockets as well; in the examples, :3001T tells the MSS
		to form a raw TCP connection to socket 3001.
		Note: If the host software does not accept a colon (:), use a comma
		(,) instead.
	ATE	Echo mode off (ATE0) or on (ATE1, the default).
	ATH	Disconnects the network session.
	ATI	Displays modem version information.
	ATQ	Result codes on (ATQ0, the default) or off (ATQ1).
		Allows serially-attached devices to control how the MSS accepts a network
		call.
		ATS0=0 will cause the MSS to send the RING string to the serial device
	ATS	when it receives a network connection request. The serial device must
		reply with the ATA string.
		ATS0=1 allows the MSS to automatically accept network connections (the
		default).
		Displays result codes. There are four options:
		ATV0 = numeric codes, bad commands return an error.
	ATV	ATV1 = text codes, bad commands return an error.
		ATV2 = numeric codes, bad commands discarded.
		ATV3 = text codes, bad commands discarded.
	ATZ	Accepted but ignored.
	AT&F	Resets modem NVR to factory default settings.
	AT&W	Writes modem settings to NVR.
	AT&Z	Restores modem settings from NVR.
+++		Returns the user to the command prompt when entered from the serial port
		during a remote host connection.

Multiple commands can be entered on the same line (for example, ATE0Q1V0 will work). However, if the MSS encounters a command that it doesn't recognize, it will ignore the whole command line. For this reason, you should enter only one command per line.
