Line Commands

break

Specifies how a break is interpreted:

zoff—The IOLAN ignores the break key completely and it is not passed through to the host. This is the default setting.

zlocal—The IOLAN deals with the break locally. If the user is in a session, the break key has the same effect as a hot key.

zremote—When the break key is pressed, the IOLAN translates this into a telnet break signal which it sends to the host machine.

zbreak-interrupt—On some systems such as SunOS, XENIX, and AIX, a break received from the peripheral is not passed to the client properly. If the client wishes to make the break act like an interrupt key (for example, when the stty options

-ignbrk and brkintr are set).

map-cr-crlf

When Line Service Printer is selected, defines the default end-of-line terminator as CR-LF (ASCII carriage-return line-feed) when enabled. Default is Off.

data-logging

When enabled, serial data will be buffered if the TCP connection is lost. When the TCP connection is re-established, the buffered serial data will be sent to its destination (this option is not available when Monitor DSR, Monitor DCD, or Multihost is enabled).

The data buffer is 4K for desktop models and 32K for rack mount and medical unit models. If the data buffer is filled, incoming serial data will overwrite the oldest data.

The default is off.

flowin

Determines if input flow control is to be used. Default is On. This is active only when Line Flow Control is set to Soft, Hard, or Both.

flowout

Determines if output flow control is to be used. Default is On. This is active only when Line Flow Control is set to Soft, Hard, or Both.

hotkey-prefix

The prefix that a user types to lock a line or redraw the Menu. The default value is hex

01, which corresponds to Ctrl-a(^a) (hex value 02 would be Ctrl-b (^b), etc.):

z^a l—(Lowercase L) Locks the line until the user unlocks it. The user is prompted for a password (any password, excluding spaces) and locks the line. Next, the user must retype the password to unlock the line.

z^r—When you switch from a session back to the Menu, the screen may not be redrawn correctly. If this happens, use this command to redraw it properly. This is always Ctrl R, regardless of the Hotkey Prefix.

You can use the Hotkey Prefix key to lock a line only when the Line Lock parameter is On.

initial

Specifies the initial interface a user navigates when logging into the line; either the Menu or a prompt for the CLI. The default is CLI.

SDS, MDC specifications

Perle Systems is a leading provider of connectivity solutions, renowned for its robustness and reliability in networking hardware. Among its expansive product offerings, the MDC (Multiport Device Converter) and SDS (Serial Device Server) stand out as pivotal solutions for industries requiring seamless data communication and device management.

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.
