Terminal Selection Screen • The Terminal Selection Screen permits the administrator to define the types of terminals that may be used with the chosen configuration
Host Interface Settings • The Host Interface Section shows parameters that may be adjusted to determine the type of connection that is made from the OpenAir Linux Server to the host environment
Host Interface Settings • Host Interface Settings include: (Based on the Handler type chosen, settings will vary.) • Emulation - Emulation selection for vt100, vt220, or HP700. TN5250 and TN3270 emulations will be defaulted for that type of handler selection. • Application - The application program to be invoked by the handler at session startup. • Arguments - The arguments to the application. The default value is blank. This usually includes the alias to a target host machine defined in the TCP/IP settings area. • Host Type - This parameter is established in the Host List Setup Screen, but is considered part of the Host Interface Settings. Allowable values of this field are VTERM, TN5250, and TN3270.
Keyboard Settings • The Keyboard Sections show parameters that may be adjusted to determine how the RF terminal keyboard performs when interacting with the host application
Keyboard Settings • Keyboard Parameter Settings include: • End Key – User will terminate the session with this key • Auto Send Key – Field termination key sent when field filled • Case Conversion - Converts keyboard input on the RF terminal to all upper or all lower case, or no conversion • Mode – Block/Field or Character Mode of RF Transmission • HotKey - Function key used to switch between active sessions • Keyboard Object Editor Files include: • Mapping Object - Defines an object file used to define keyboard mappings, allowing you to map keys on your terminal to a specified host key • Macro Object - Defines an object file used to define keyboard macro settings. A macro is a sequence of key strokes resulting from pressing a single key.
Display Settings • The Display Sections show parameters that may be adjusted to determine how the RF terminal display performs when the terminal interacts with the host application
Display Settings • Display Parameter Settings include: • Quadrant Mode Processing - Dictate how the RF Terminal display presents the host session screen to the user • Scroll Mode - Defines the scrolling method used (full or half) when using the scrolling keys • Language - The language used for terminal error messaging • Display Object Editor Files include: • Mapping Object - Defines an object file that allows non-defined host characters to be displayed on the terminal. • Dialog Object - Defines an object file script used for automated logons. • Formatter Object - Defines an object file that contains reformatted host screens sized to fit on a smaller terminal screen.
