12.1.4 Setting up the Serial Ethernet Gateway
The serial Ethernet gateway enables the addressing of serial end devices from the local
network of the MoRoS Modem - ISDN 1.3 or from a remote network, which are con-
nected to the serial interface of the MoRoS Modem - ISDN 1.3. The data which is sent to a
configurable network port of the MoRoS Modem - ISDN 1.3 is output at the serial inter-
face of the MoRoS Modem - ISDN 1.3. In the variant Pro, the serial interface can also be
used to connect a redundant communication device. In this case, the interface can not be
used as serial Ethernet gateway.
Configuration with the web interface
To set up the serial Ethernet gateway, activate the checkbox "Activate serial
Ethernet gateway" in the menu "Basic settings" on the page "Serial Ethernet
gateway" (Figure 10, page 32 above, position 1).
The port, which the serial Ethernet gateway uses to accept a TCP connection,
is entered in the entry field "Port" (Figure 10, page 32 above, position 6).
The speed of the serial interface is set in the entry field "Speed (in Bit/s)"
(Figure 10, page 32 above, position 2).
The data flow control (RTS/CTS handshake) is set in the entry field "Flow con-
trol" (Figure 10, page 32 above, position 3). If the connected serial device does
not support the RTS/CTS lines, you must deactivate the flow control.
The data format of the serial interface is set in the entry field "Data bits"
(Figure 10, page 32 above, position 9).
To use the control lines DCD and DTR, activate the checkbox "Use control
lines" (Figure 10, page 32 above, position 8).
To reset the control lines after the connection is terminated, activate the
checkbox "Reset control lines after the connection was terminated" (Figure 10,
page 32 above, position 4).
To automatically terminate a TCP connection, if no data transfer occurs any
more, set a value in seconds in the entry field "Timeout" (Figure 10, page 32
above, position 5). If no data transfer occurs for the time set, the TCP connec-
tion, which was established by a computer to the serial Ethernet gateway, is
closed. To ensure that the connection is never terminated, set the value Zero.
The value Zero is the default setting.
Save the settings by clicking "OK" (Figure 10, page 32 above, position 7).
12.2 DNS
12.2.1 Setting up DNS Forwarding
You may use the MoRoS Modem - ISDN 1.3 as DNS relay server. When the MoRoS Modem
- ISDN 1.3 is configured as DNS server at the locally connected network devices, the Mo-
