Description
(Used only when Allow Incoming Calls is enabled.) Specifies the port where the ESP hub will
listen for incoming connection requests.
If the all ports option is being used for configuration, this value specifies the local IP port
base. Each port's actual local IP port number will be the base plus the port number. For
example, if 6000 is specified as the base, the local IP port number for port 1 will be 6001, port
2 will be 6002 and so on.
This value (or its result when using the all ports option) must meet the following criteria:
• It cannot conflict with the port numbers specified for other enabled connection methods on
any port.
• Valid values are 1024-65535, except 4000 and 4100, which are reserved.
• When using the all ports option, 4000 or 4100 may be used as the base. However, you
cannot specify a base that, when added to a port number, will equal 4000 or 4100.
When using the all ports option, all ports must be valid or the entire selection will not
be accepted.
The default value is 5001 for port 1, 5002 for port 2 and so on.
Enables or disables outgoing calls (that is, establishing a raw TCP connection in response to
AT commands received on the serial port). When this option is enabled, you may also set the
Default IP Address and Default IP Port options, which will be used if an ATDT modem
command is issued without parameters. When this option is disabled, valid ATDT strings will
be ignored. See Outgoing calls on page 26 for more information.
The default value is enabled.
(Used only when Allow Outgoing Calls is enabled.) Specifies the IP address to be used when
an ATDT modem command is entered without an IP address. The address cannot be 0.0.x.x,
127.x.x.x, 248-255.x.x.x or the IP address of the ESP hub.
(Used only when Allow Outgoing Calls is enabled.) Specifies the IP port number to be used
when an ATDT modem command is entered without an IP port. Valid values are 0-65535. (If
the destination IP port is on an ESP MI hub, 4000 and 4100 should not be used.)
If the all ports option is being used for configuration, this value specifies the destination IP
port base. Each port's actual destination IP port number will be the base plus the port
number. For example, if 6000 is specified as the destination IP port base, the destination IP
port number for port 1 will be 6001, port 2 will be 6002 and so on.
The default value is 5001 for port 1, 5002 for port 2 and so on.
Enables or disables echo mode. When enabled, modem commands are echoed to the
attached serial device. When disabled, modem commands are not echoed. (This option
affects only modem commands, not session data.)
The default value is enabled.
This option is equivalent to an ATE modem command. If an ATE command is issued with a
different value, the new value will be used during that connection but it will not replace this
configured value. The configured Echo value will be used for subsequent connections.
