Configuring Ports
Introduction
This chapter provides information on configuring serial ports. Key port configuration attributes include the host mode, which
defines a type of communication between the port and a remote host, the protocol, authentication, user access restrictions, and
serial communication attributes.
Host Mode Configuration
The SERIMUX provides four modes of communication between serial devices and remote hosts. Console server, terminal server,
dial-in modem, and dial-in terminal server. These are described in the following sections.
Console Server Mode
Configuring a serial port as a console server creates a TCP socket on the SERIMUX that listens for a Telnet or SSH client
connection. Users who connect to the TCP socket have access to the device attached to the serial port as though the
device were connected directly to the network. RawTCP is also supported with the Console Server Mode.

Terminal Server Mode
In terminal server mode, the SERIMUX serial port is configured to wait for data from the device connected to the port. If data is
detected, the SERIMUX starts a TCP session as a Telnet or SSH client to a pre-defined server. The server must be defined by the
user before the port can be configured for a Telnet or SSH client. This mode is used when the user wants to access servers on
the network from a serial terminal. RawTCP is also supported with the Terminal Server Mode.
