mfterm
Interact with mainframe systems through terminal
SYNOPSIS
mfterm [options] [hostname|ip_address]
PARAMETERS
hostname|ip_address
Specifies the target mainframe's network address (hostname or IP address) to establish the connection.
-p port
Defines the TCP port number for the connection, commonly 23 for Telnet or 3270 for TN3270 sessions.
-t term_type
Sets the terminal emulation type, such as IBM-3278-2, IBM-3279-2, or IBM-3279-5, to match the mainframe's expected display configuration.
-s session_id
Specifies a unique identifier for a particular session, useful for managing multiple connections.
-f config_file
Loads connection and session parameters from a specified configuration file, allowing for predefined settings.
-L log_file
Enables logging of session activity, including data exchanged, to the designated log file path.
--help
Displays a summary of command-line options and usage information.
DESCRIPTION
The mfterm command is a proprietary utility provided by Micro Focus as part of their enterprise software suite, primarily functioning as an IBM 3270 terminal emulator. Unlike standard Linux commands, it is not typically found in common operating system distributions. Its core purpose is to facilitate secure and interactive communication with IBM mainframe systems, allowing users to access applications like TSO, CICS, and IMS from a Linux environment. The command provides a character-based interface that mimics the behavior and display of an IBM 3270 series terminal. Due to its commercial and specialized nature, comprehensive public documentation (such as standard man pages) is scarce. Users are advised to consult the specific documentation provided with their Micro Focus product installation for definitive details on its usage, options, and capabilities.
CAVEATS
The mfterm command is a proprietary component of Micro Focus software products and is not a standard, open-source, or universally available Linux utility. Its presence, behavior, and specific command-line options are entirely dependent on the Micro Focus product installation and version. Generic Linux documentation or online resources typically do not cover this command. Users should always refer to the official documentation provided by Micro Focus with their licensed software.
TYPICAL USAGE ENVIRONMENT
mfterm is predominantly utilized in corporate or development environments where access to IBM mainframes is required. This often includes mainframe application developers, system administrators managing mainframe-connected resources, or end-users running specific enterprise applications. It integrates within a larger Micro Focus ecosystem, often alongside tools for application re-hosting, development, or testing.
HISTORY
The mfterm utility is part of Micro Focus's historical dedication to providing robust enterprise solutions, particularly in the realm of mainframe connectivity and modernization. Its development lineage traces back to the need for reliable terminal emulation tools that could operate across various Unix and Linux environments, bridging legacy IBM mainframe systems with modern IT infrastructures. While specific version histories are tied to Micro Focus product releases, its existence reflects a long-standing requirement in corporate environments for accessing mainframe applications from diverse platforms.
