Telnet

Description Starts a telnet session to the specified host/IP address.

User Level Normal, Admin

Syntax telnet <hostname/IP_address> [<TCP_port>] [termtype <terminal_name>] [line-mode onoff] [map-cr-crlf onoff] [local-echo onoff]

[echo <00-7f>] [eof <00-7f>] [erase <00-7f>] [intr <00-7f>] [quit <00-7f>] [escape <00-7f>]

Options <hostname/IP_address>

The name (resolvable via DNS) or IP address of the host you wish to connect to with

Telnet.

<TCP_port>

The port number the target host is listening on for incoming connections. The default for Telnet is port number 23.

termtype

Type of terminal attached to this line; for example, ANSI or WYSE60.

line-mode

When On, keyboard input is not sent to the remote host until Enter is pressed, otherwise input is sent every time a key is pressed. Default is Off.

map-cr-crlf

Maps carriage returns (CR) to carriage return line feed (CRLF). The default value is

Off.

local-echo

Toggles between local echo of entered characters and suppressing local echo. Local echo is used for normal processing, while suppressing the echo is convenient for entering text that should not be displayed on the screen, such as passwords. This parameter can only be used when Line Mode is On. Default is Off.

echo

Defines the echo character. When Line Mode is On, typing the echo character echoes the text locally and sends only completed lines to the host. This value is in hexadecimal with a default value of 5 (ASCII value ^E).

eof

Defines the end-of-file character. When Line Mode is On, entering the EOF character as the first character on a line sends the character to the remote host. This value is in hexadecimal with a default value of 4 (ASCII value ^D).

erase

Defines the erase character. When Line Mode is Off, typing the erase character erases one character. This value is in hexadecimal with a default value of 8 (ASCII value ^H).

intr

Defines the interrupt character. Typing the interrupt character interrupts the current process. This value is in hexadecimal with a default value of 3 (ASCII value ^C).

quit

Defines the quit character. Typing the quit character closes and exits the current telnet session. This value is in hexadecimal with a default value of 1c (ASCII value FS).

The Perle MDC serves as a powerful multi-port device converter, providing the ability to connect multiple serial devices to a computer network without needing a separate connection for each device. This is particularly useful in environments with limited computing resources or high device density, such as railways, manufacturing plants, or remote field operations. It is designed to convert serial communication, which is commonly used in legacy devices, into Ethernet/IP or TCP/IP protocols, ensuring that older devices can integrate into modern networks.

Main features of the MDC include its robust design for industrial environments, support for a variety of serial protocols, and multiple device connections. It supports data rates of up to 115200 bps and provides easy monitoring and configuration via a web-based interface. Additionally, the MDC incorporates advanced security features including SSL and SSH encryption, ensuring data integrity and protection against unauthorized access.

On the other hand, the Perle SDS model exemplifies advanced serial device hosting capabilities, allowing users to connect Ethernet networks to serial devices. It acts as a bridge, enabling remote devices to be configured and managed over IP networks. The SDS series is known for its versatility, supporting a range of serial communication protocols, including RS-232, RS-422, and RS-485, making it suitable for various applications such as point-of-sale systems, industrial automation, and remote monitoring.

The SDS boasts several characteristics that enhance its functionality, such as automatic device discovery, real-time monitoring, and local or cloud-based management options. Its feature set also includes traffic management capabilities, allowing the optimization of device communication by controlling the flow of data, which is critical for applications requiring high reliability and low latency.

Both the MDC and SDS benefit from a strong emphasis on ease of deployment and management. They support a range of network topologies, facilitating seamless integration into existing infrastructures. Furthermore, these devices are backed by Perle Systems' reputation for customer support and a commitment to ongoing innovation, ensuring that organizations can rely on these solutions for future growth and technological advancement.
