COM Port Redirector with Encryption
SENA now takes COM Port Redirection a step further with encryption
features, offering a secure Ethernet connection between the COM port and a
SENA device server or terminal server. When working with the Serial/IP COM
Port Redirector and OpenSSL Toolkit, the new SSL/TLS Security option
offers a selection of five ciphers (including 3-DES and AES) and strengths
up to 256 bits, sufficient to meet the tough security requirements
encountered in the financial services industry.

COM Port Control protocol support
For some serial applications that require features provided by the COM
Port Control protocol specified by IETF RFC 2217, SENA has a solution when
working with the Serial/IP COM port redirector.

Tunneling Mode
Serial tunneling occurs when two device servers are configured to work
together to share or communicate their respective serial device's data.
The serial tunnel is established by connecting one device server
configured for Server/Client mode to a device collecting data and the
other device server configured for Server/Client mode to the field device
sending data. This allows two previously non-networked and isolated
devices to communicate information and operate with existing installed
software applications of devices on a network, instead of a long serial
cable.

Modem Emulation
Modem emulation feature enables a networked SENA product to act as a
modem to send and receive data over an IP network instead of a PSTN.
Furthermore, SENA's high-end product lines, Super and STS Series supports
Modem Emulation mode over SSL encryption. This unique feature provides
secure serial modem emulation, accepting AT commands in an encrypted
format to connect and communicate with Serial devices.

Secure Communication
SENA products support Security features such as static key based 3DES
data encryption, and SSL for secure connection between a client and a
server, over which any amount of data can be sent securely. In addition,
HTTPS for secure data transfer over the web, SCP for secure file transfer,
and IP filtering controls the access to serial devices.

Custom Application Support - Deploy your own embedded Linux applications
One of the strengths of SENA's products is their flexibility. Since no
two solutions are the same, STS Series product line has been designed to
correctly facilitate the connection in any situation. The STS Series
Device Server is intended for the deployment of your own embedded Linux
applications.
Users can customize the web management interface, and integrate the
programmed dynamic web pages to web menu. In addition, Users can
manipulate the raw data stream between remote host and serial device by
adding a filtering program. The user-defined filter program communicates
with other programs that are reading/writing serial port and socket by
using FIFO, and so users can easily manipulate the serial data without
programming related to serial port and socket. SENA is committed to
open-source development and fully supporting its customers.

Virtual COM Mode
Virtual COM Mode of SENA device and terminal servers uses a driver to
create a "Virtual COM Port" so that the software thinks it's talking to a
serial port, but it's really talking to a LAN. The serial port may be
anywhere on the LAN.
After connection, the LAN is transparent to the program and serial
device. Applications work just as if the serial device is connected
directly to a physical COM port on the PC. In addition, when working with
Serial/IP COM port redirector, SENA device servers transmit all serial
signals including DTR, DSR and DCD.

Port Logging
Port Logging feature allows user to keep Serial and TCP data safely in
data storage locations such as NFS Server, Syslog server, Internal memory
and PCMCIA Flash Memory card. This facilitates future examination of the
events that occurred on a specific port prior to an alarm or failure.

Multiple Access for Port
SENA products support multiple sessions for a port that provides the
ability for device servers or terminal servers to allow multiple hosts to
connect to a serial device simultaneously.
This feature is particularly useful in applications that require
failover alternative connections and applications that need multiple
accesses to share communications with a particular device.

Multicasting
SENA products support an enhancement transmission method "TCP/UDP
multicasting", which automatically broadcasts the same serial data to up
to 32 remote destinations simultaneously by TCP packet or by UDP datagram.
The device server transmits the data to the multiple host computers at the
same time in the network data collection system. This feature is very
useful in the applications where multiple management stations want to
collect data from the same data acquisition system as if they may share
it.
