Serial Console Server User Manual

Operating Mode
For detailed information about the settings in each of the Operating Modes, see
Operating Mode
, page 73.
Console Management
Console Management mode is the most common Operating Mode used,
allowing users to establish Telnet or SSH sessions to the Serial Console Server
to manage the serial devices. In this mode users can log in using the web
browser’s built in SNViewer application via
Telnet
or
SSH
; remotely via Telnet
or PuTTY; or directly using the HyperTerminal or SNViewerUSB
applications.
For information about configuring
Console Management
settings, see page 73.
Note: Be sure that the
Socket
entry specified on the
Network
page corresponds
to the port that the device listens on. 5001 is the Serial Console Server’s
default setting (see
Network
, page 101, and
Base Socket
, page 102).
Real COM Port
This mode is used in conjunction with a virtual COM port driver installed on
the remote user’s local computer. When the Serial Console Server’s COM port
is set to this mode, the device connected to the port appears as if it were a
device directly connected to a COM port on the remote user’s local computer.
This mode is useful with devices such POS terminals, Bar Code Readers, Serial
printers, etc. since it allows you to use software that was written for pure serial
communication applications.
The Serial Console Server comes with Real COM drivers for Windows
systems and TTY drivers for Linux systems.
For information about configuring
Real COM Port
settings, see page 73.
TCP Server / TCP Client (Serial Tunnel)
TCP (Transmission Control Protocol) provides a reliable transport layer for
transmitting serial data over the TCP protocol via socket programming.
TCP Server (RAW TCP)
In
TCP Server
(RAW TCP) mode, data transmission is bidirectional. In this
mode, the host computer initiates contact with the Serial Console Server and
requests a connection to its serial port.
