Incoming calls

When the Allow Incoming Calls option is enabled, the ESP-2 hub will listen on the
specified TCP port for connection requests from the network. If another call is active,
an incoming connection request will be rejected.
If the Monitor DCD option is enabled, the connection will be rejected if the control
signal is logically low. The connection will be closed if the inbound control signal
changes from logically high to low.
When a TCP connection is active, the ESP-2 hub will raise the outbound DTR signal
to indicate that the connection is valid (which should be seen as inbound DCD by the
serial device). If the remote end breaks the TCP connection, DTR will be lowered to
indicate a Carrier Drop to the attached serial device.

3.6 Configuration Utility

The configuration utility connection method may be used on either of the ESP-2 serial
ports. Using the internal configuration utility, you may specify attributes of the ESP-2
hub and its serial ports. This includes enabling serial port connection methods and
specifying their configurable items, plus configuring serial port attributes. The menu-
based interface also allows you to configure network parameters, download and
install FLASH images, reboot, reinitialize and monitor ESP-2 hub status.
See Configuration Utility on page 32 for more information.
Table 13 describes this method's configurable items for each serial port.
Table 13: Configuration Utility Connection Method Configurable Items
Item Description
Enables or disables the configuration utility connection method on the port.
Enable/ The default value is enabled for port 1 and disabled for port 2. This method
disable cannot be enabled if the raw TCP client connection method is already enabled
on the port.
Specifies the length of time before the configuration utility is disconnected if
there is no activity. Valid values are 0-65535 seconds.
Inactivity time-
For example, a value of 60 indicates the configuration utility will be
out
disconnected if there is no activity for a period of 60 seconds.
A 0 value disables the inactivity time-out. The default value is 0 (disabled).

3.7 Serial Port Attributes

Each serial port has a set of attributes which may be modified.
NOTE: When a port is configured for the serial port redirection connection method, the attributes
are specified within the protocol. Therefore, although you may change the attributes, any
changes you specify will not take effect.
