Airlink manual Host RJ-11 IP Gateway Port Services

Configuration Settings and Commands

•With Modem Signal Loopbacks, the Host RJ-11 IP Gateway eliminates the use of specialized cables required to change signal types and directions by performing the loopback of signal types to other signal types internally.

•NativeCOM, (or any RFC-2217 Telnet client with COM-PORT-OPTION support) overrides the baud rate, size, parity, stop bits and flow control parameters.

Port Services

By default, the RJ-11 port is configured to accept incoming TCP connections from TCP/telnet cli- ents with outgoing service based on phone numbers dialed by the attached device (Modem Ser- vice). You may configure the ports to initiate outgoing raw TCP or telnet connections to remote servers. In addition, the modem emulation feature may be enabled to allow a serial port to mimic a modem interface.

•When using the modem service on the port, the phone number will be translated to a host/port pair then a TCP connection will be established to the remote host.

•When using outgoing connections on the port, the settings configured on the Serial Settings page will be applied to the port, and a TCP connection will be established to the remote host.

•Once connected, data received on the port is sent to the remote server over the network connec- tion and data received on the network connection is sent out the port.

•No Outgoing Service: Disables outgoing port services on the specified port. Incoming connec- tions are still allowed. All port services options will reset to defaults.
