Host RJ-11 IP Gateway User Guide, version 22
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.
