1 Using the x6530 Emulator The x6530 Emulator is a terminal emulator in the X Window System environment that gives you access to a Tandem system from your workstation. It is analogous to xterm, the terminal emulator described in the X Window System User’s Guide. When you have an x6530 window displayed at your workstation, you can log on to a Tandem host to execute any program or TACL command residing there. You can also have more than one x6530 window displayed at your workstation at a time.
Using the x6530 Emulator x6530 Window Note The window shown in Figure 1-1 is a generalization. The actual appearance of the window depends on the specific window-manager software in use, so details may vary. To access the Tandem host, follow these steps: 1. Enter tacl at the Enter Choice> prompt to get to the TACL prompt. 2. Log on to the Tandem host when the TACL prompt appears. Logging on requires a Tandem logon ID and password. 3. Enter a TACL command or the name of a Tandem program.
Using the x6530 Emulator x6530 Window Having Tandem programs run in separate x6530 windows is a convenient way to use them. You can switch back and forth between the windows rather than interrupt your work in one x6530 window to start another program. For example, you could have Peruse, FUP, and PS Mail running in x6530 windows of their own, keeping the original x6530 window for other tasks.
Using the x6530 Emulator x6530 Window Pointer Cursor The pointer cursor is used to: Track the movement of your mouse around the screen. Manipulate windows and icons. Select items in menus. Select the window in which you want to enter characters. Note This manual assumes you have a three-button mouse attached to your workstation. The buttons are referred to as the right mouse button, middle mouse button, and left mouse button.
Using the x6530 Emulator x6530 Menus x6530 Menus The x6530 Emulator has one standard pop-up menu, with three additional submenus that cascade down from it: the Custom Commands, Emulator Options, and Configuration Info menus. These menus are described in this subsection. When using the x6530 menus, the pointer changes to an arrow (different from the alternative pointer that can be configured for x6530 operations). On returning from the menus to the x6530 window, the pointer reverts to its default shape.
Using the x6530 Emulator x6530 Menus Table 1-1. x6530 Menu Options Option Description About x6530 Brings up a text window showing version information about x6530 and about the X server that is currently running. Cascades to a menu containing the names of Tandem programs that can be started simply by selecting them from this menu. Cascades to a menu containing options that affect the appearance and actions of the x6530 window.
Using the x6530 Emulator x6530 Menus Custom Commands Menu The Custom Commands menu, shown in Figure 1-3, provides a quick way of starting Tandem programs. To run a program, simply select its name from this menu. Figure 1-3. Custom Commands Menu 004 The contents of this menu are defined by the .x6530rc file. See Section 2, “x6530 Run Command and Customizing Options,” for a description of the entries in that file.
Using the x6530 Emulator x6530 Menus Emulator Options Menu The Emulator Options menu allows you to change options that affect the appearance of the x6530 window and the way x6530 handles text. You can switch these options on and off during the current session; the changes you make are in effect for the current session only. The Emulator Options menu is shown in Figure 1-4. Figure 1-4.
Using the x6530 Emulator x6530 Menus Table 1-2. Emulator Options Menu Choices Option Description Jump Scroll Turns on jump scroll, a faster method of scrolling lines in a window. Using this menu option is the same as using the command line option -j (see Section 2). Reverses the foreground and background colors. Using this option is the same as using the command line option -rv (see the X Window System User’s Guide). Rings a margin bell when you type near the right margin.
Using the x6530 Emulator x6530 Menus Configuration Info Menu The Configuration Info menu lets you display any of three sets of information about the x6530 configuration. The Configuration Info menu is shown in Figure 1-5. Figure 1-5.
Using the x6530 Emulator x6530 Menus Display Resources Option The Display Resources option pops up a text window that shows the status of every option that can be configured, such as the display font, the name of the keymap file in use, the name of the custom command file, the shape of the pointer, and so on. Figure 1-6 is an example of this display. Figure 1-6. Resources Display 007 To close the display and return to the x6530 window, click on the “OK” button.
Using the x6530 Emulator x6530 Menus Display Keymaps Option The Display Keymaps option pops up a text window that shows the current mapping of every 6530 key. The 6530 keys are listed in alphabetic order for quick reference. Some 6530 keys may be mapped to more than one workstation key; an additional line is displayed for each additional definition. Figure 1-7 is an example of a keymaps display. Figure 1-7. Keymaps Display 008 To close the display and return to the x6530 window, click on the “OK” button.
Using the x6530 Emulator x6530 Menus Display Character Classes Option The Display Character Classes option pops up a text window that shows the members of each character class for reference purposes. Figure 1-8 is an example of a character classes display. Figure 1-8 . Character Classes Display 009 To close the display and return to the x6530 window, click on the “OK” button. Alternatively, you can press the Return or Enter key.
Using the x6530 Emulator x6530 Special Features x6530 Special Features The x6530 Emulator has three special features associated with a mouse or other pointing device. These features include: Scrolling and paging through text with the scrollbar. Simulating a 6530 function key. Copying and pasting text within the same x6530 window or between windows.
Using the x6530 Emulator x6530 Special Features Using the Scrollbar in Conversational Mode In conversational mode, the position of the slider within the scroll region represents the position within the work area of the text that is currently visible in the window. The size of the slider in relation to the scroll region represents the amount of visible text in relation to the total amount of text in the work area.
Using the x6530 Emulator x6530 Special Features Many Tandem block-mode applications use paging keys on the 6530 terminal to view text that has scrolled off the screen. Table 1-4 shows the use of the scrollbar to simulate the actions of the paging keys: Table 1-4. Scrollbar Functions in Block Mode 6530 Key Mouse Action RollUp Place the pointer on the down arrow button and click the left mouse button. Hold down the mouse button to continue scrolling.
Using the x6530 Emulator x6530 Special Features Copying and Pasting Unprotected Text Text from one x6530 window can be copied to another window, or copied within the same window. The first step is selecting the text you want pasted elsewhere (selecting text also copies it into the select buffer, ready for pasting in a new location). There are four ways in which unprotected text can be selected: By word By line By page By block Selecting Text By Word To select the text by word: Note 1.
Using the x6530 Emulator x6530 Special Features To select the text by dragging the pointer cursor: 1. Position the pointer over the first character to copy. 2. Hold down the left mouse button; do not release it until you have selected all the characters to be copied. 3. Drag the pointer over the characters to copy. As the pointer is dragged, the selected characters are highlighted. 4. When you have selected all the text to copy, release the left mouse button.
2 x6530 Run Command and Customizing Options This section is for system administrators, experienced with the X Window System and UNIX, who will set up x6530 for users. References to “user” mean a person using a workstation with an X server who may be running x6530 locally or who may access a remote machine to run x6530; references to “you” mean the system administrator. Running x6530 means executing a run command at the UNIX workstation where x6530 resides.

x6530 Run Command and Customizing Options Reading Tandem Commands From a File Reading Tandem When the -exec or -dexec command line option is used, x6530 initially looks for Commands From Tandem commands in a file, rather than receiving them from a keyboard. If you press a File any key on the keyboard while x6530 is reading the -exec or -dexec file, x6530 stops processing the file immediately and awaits further input from the keyboard.
x6530 Run Command and Customizing Options x6530 Custom Commands Menu command that lists the file names in the user’s default volume on the Tandem host. After files has been executed, the user is left at the TACL prompt. When x6530 is finished with the command file, it proceeds interactively. When the -exec option is used, the command file is kept after x6530 reads it. When the -dexec option is used, the command file is deleted after it is read.
x6530 Run Command and Customizing Options x6530 Custom Commands Menu Example The following example of a .x6530rc file shows the two types of custom menu items: USER PASSWORD "FUP" "Peruse" hardware.engr sos ! fup > peruse Tandem logon information (the first three file entries) is included because FUP is set up to be displayed in a separate x6530 window.

x6530 Run Command and Customizing Options Creating a New Keymap File Keymap Files The x6530 Emulator can assign any key or any combination of keys on a workstation keyboard to a 6530 terminal key or function by using the information in a keymap file. Keymap files reside on the workstation that x6530 runs on, not the workstation where the x6530 window displays its output. Keymap files depend on the X server and keyboard of a workstation. Several sample keymap files are provided with x6530.
x6530 Run Command and Customizing Options Creating a New Keymap File Figure 2-2.
x6530 Run Command and Customizing Options Creating a New Keymap File Here is one way to create a new keymap file and the steps to follow: 1. Copy an existing sample keymap file from the Tandem host or the UNIX workstation to the user’s home directory and rename it “.x6530modkey.” The sample keymap file gives you a template of all the 6530 terminal functions to define. 2.
x6530 Run Command and Customizing Options Creating a New Keymap File 4. Update all the comments at the beginning of the keymap file. You should be able to look at these comments and find any key on the keyboard and its keysym. 5. Each line of a keymap file defines one 6530 terminal key or function. A 6530 terminal key or function can have more than one definition.
x6530 Run Command and Customizing Options Creating a New Keymap File To assign PC keyboard keys to the 6530 function keys, the following keysyms are assigned in the keymap file: F11 F12 F13 Control_L F1 Control_L F2 Control_L F3 In this example, when a user presses the Ctrl key and the F1, F2, or F3 key, x6530 interprets that as F11, F12, or F13, respectively.
