Port Services
By default, all ports are configured to accept incoming TCP connections from TCP/telnet
clients and no outgoing service is configured. You may configure the ports to initiate
outgoing raw TCP (with or without SSL) 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.
A note about port naming and numbering: the gateway ports are labeled “POS Serial” (1 and
2), “POS Terminal” (1, 2, 3 and 4), and “Modem”. In this manual and in the web
configuration screens the ports are referred to as Serial1, Serial2, Terminal1, Terminal2,
Terminal3, Terminal4 and Modem. For incoming connections, the ports are numbered as
follows:
Port
Incoming
Telnet Port
Raw TCP
Port
Serial1
9001
8001
Serial2
9002
8002
Terminal1
9003

Terminal2
9004

Terminal3
9005

Terminal4

Modem

When using the modem service on a 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 a 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.
If Require carrier/Generate hangups is set, the service will wait for the presence of the DCD
modem signal before connecting.
Once connected, data received on the port is sent to the remote server over the network
connection and data received on the network connection is sent out the port.
The following screen shot represents most of the options available for configuration.
Depending on the Service Type you have selected, not all of these options will be displayed.
