ATS0=n
Enables or disables connections from the network going to the serial port:
n=0 disables the ability to make a connection from the network to the
serial port.
n=1-9 enables the ability to make a connection from the network
to the serial port.
n>1-9 is invalid.
ATEn
Enables or disables character echo and responses:
n=0 disables character echo and responses.
n=1 enables character echo and responses.
ATVn
Enables 1-character response or full verbose:
n=0 enables 1-character response.
n=1 enables full verbose.
Note: The unit only recognizes these AT commands as single commands
like ATE0 or ATV. It does not recognize compound commands such as
ATE0V1. All other AT commands with Modem Mode set to full verbose
acknowledge with an OK, but the unit takes no action.
Remote IP Address
This is the destination IP address used with an outgoing connection.
Remote Port
The remote TCP port number must be set for the unit to make outgoing connections.
This parameter defines the port number on the target host to which a connection is
attempted.
Note: To connect an ASCII terminal to a host using the unit for login
purposes, use the remote port number 23 (Internet standard port number for
Telnet services).
