Configuring Incoming Network Connections via Telnet Server
The gateway is pre-configured to accept incoming TCP connections from TCP socket-based
applications. Each Systech serial port accepts incoming TCP connections on two TCP ports:
an 8000-series port (for raw data), and a 9000-series port (for telnet data).
The 8000-series port (8001 for port 1, or 800N for port N) is a raw data path that passes all
data back and forth between the network and the serial device without further processing. It
should be used by applications that support simple TCP connections and do not implement
the telnet protocol. There is no protocol involved beyond TCP/IP.
The 9000-series port (9001 for port 1, or 900N for port N) implements the telnet protocol and
supports the following telnet options: SUPPRESS GOAHEAD, BINARY, ECHO, COM-
PORT-OPTION and TIMING MARK. It should be used by the Systech NativeCOM driver,
and by other applications that support telnet.
