NetComm Wireless 3G M2M Router / Plus
74
Turns on or off the modem emulator function of the router.
The device name of the serial port.
The configuration status of the serial port. This will display whether there are any conflicts with the serial port
preventing modem emulator from working properly.
The serial (V.24) port baud rate. By default the serial line format is 8 data bits, No parity, 1 Stop bit.
Refer to the AT (V.250) AT Command Manual if you need to change the serial line format.
The Modem emulator buffers any bytes received from the serial port until either 512 bytes have been received or
no bytes have been received for "Inter Character Timeout" milliseconds, it will then send any bytes in the buffer to
the remote host.
When the ID field is not blank (empty) the defined ID will be sent to the remote host as follows:
For UDP the 1st <n> bytes of each datagram sent will be set to the contents of the ID field, data follows
immediately after the ID for TCP the ID is transmitted once immediately after the connection is established
When the "Ignore String" field is not blank (empty) the router will strip any character sequence that matches the
"Ignore String" from the data stream received from the serial port.
Determines how the router behaves when it receives an "ATD" command on the serial port.
• Profile - Connect using "Data Connection Profile"
• Circuit - Establish a circuit switched data connection
• Packet - Connect to cellular packet network in PPP pass through mode
• DialString - Examine the dialed digits and connect to Profile, Circuit or Packet as appropriate
Determines how the router responds to change of state of the serial port DTR line
• Ignore - Take no action
• Command - High to Low transition of DTR causes the router to enter command mode (does not end call).
• Hangup - High to Low transition of DTR causes the router to end call and enter command mode.
• High AutoDial - Low to High transition of DTR causes the router to dial the Auto Dial Number, High to Low
transition of DTR causes the router to end call and enter command mode.
• Low AutoDial - High to Low transition of DTR causes the router to dial the Auto Dial Number, Low to High
transition of DTR causes the router to end call and enter command mode.
• Low Pass To AT Port - When DTR is low pass all AT commands directly to internal cellular data engine.
• Off - Serial port flow control off
• Hardware - Serial port uses RTS/CTS flow control
Determines how the router controls the state of the serial port RI line
• Always On - RI is always on
• Incoming Ring - RI is on when an incoming connection request is received.
• Always Off - RI is always off
Sets the number of incoming rings after which the router will answer incoming circuit switched data calls.
Sets the number the router will dial if DTR Auto Dial is enabled ad DTR changes state.
Choose the profile that you want to configure.
In client mode (router connects to host) this is the remote host to which the router will connect.
In server mode (remote host connects to router) the router will only accept incoming connections from the
specified host. If you specify 0.0.0.0 the router will accept incoming connections from any host.
TCP/UDP port number to use
Refer to the AT (V.250) Command Manual for details of this parameter, this is normally disabled.
Selects the mode of operation for the chosen profile. Mode may be TCP, UDP or GMTP.
When enabled the router accepts incoming connections (enables server mode)
