THANK YOU for evaluating the demonstration version of DoubleVIEW, DigiBoard's solution to combining DOS applications and UNIX connectivity. This demonstration version has been limited in several respects, and has had some features removed. Here are the limitations: * Parameters cannot be saved. You will need to select your terminal emulation, baud rate, keyboard type, etc. each time you load DoubleVIEW. * You can only 'hot-key' into DoubleVIEW a limited number of times before reloading the program is necessary. * SCO MSCREEN (multiple login screens) is not supported in this demonstration version, page memory is not allocated. * DCOPY, the UNIX/DOS file transfer program, is not included. QuickStart - How to Use this Demo (More detailed instructions follow.) 1...Connect your computer to another Host computer, either by serial link or by modem. 2...Load the demo by typing DBVDEMO at the command prompt. 3...Press Alt-V to enter DoubleVIEW. 4...Once in DoubleVIEW, press Alt-S to enter the Setup Screens. 5...Change the various parameters (terminal type, COM port, baud rate, etc.)to match your needs. 6...Press ESC to exit the setup screens and go on-line. DoubleVIEW Description DoubleVIEW is a terminal emulator program; it makes your PC keyboard and screen display act like the standard video terminals normally connected to a multi-user operating system. DoubleVIEW lets you access your UNIX or other multi-user operating system host computer from your PC-compatible computer running under PC-DOS OR MS-DOS. DoubleVIEW also includes DCOPY, a utility that lets you transfer ASCII or binary files between your DOS PC and a multi-user UNIX host computer. Also included is a 'Cut-and-Paste' feature for moving small amounts of information between applications without retyping. DoubleVIEW was designed as a Terminate and Stay Resident or 'TSR' program. TSRs are programs that, once loaded, stay in memory and can be called up at any time from DOS or from inside almost any software application, just by pressing a special key combination called the 'hot-key.' DoubleVIEW can also unload itself and release it's RAM to other applications. The full-featured version of DoubleVIEW can also be run in a non-TSR mode. A powerful DoubleVIEW feature are the twenty softkeys that you can program with often-used keystroke sequences to avoid repetitive typing. The twenty softkeys can also be used to call scripts, which are disk files containing series of commands in DoubleVIEW's own programming language. These scripts can be used to further automate repetitive communication tasks. For example, a script can be written to automatically dial up a remote multi-user computer,wait for a CONNECT signal, log you in, enter your password, print a report, then log you out, all at the touch of a key. A script debug feature is included to help you debug your script programs. DoubleVIEW also manages SCO's Multiple Screens (MSCREEN) support for several simultaneous operating sessions from one console. Up to seven screens are supported for all emulations, not just the SCO ANSI console. SYSTEM Requirements DoubleVIEW requires an IBM PC, XT, AT, or compatible, or a PS/2 or equivalent, with a minimum of 68K of free RAM memory (not used by DOS or application programs). One or two disk drives are necessary (a hard disk is preferred) and you'll need an 80x25 monochrome or color monitor. You'll also need appropriate asynchronous serial cabling to your Host computer, or an internal or external modem (if your Host has modems, too). DoubleVIEW requires that you be running DOS 3.0 or higher. Starting the Demonstration Program Before you can use DoubleVIEW to communicate with a host computer, your PC and the host need to be connected, either by a direct serial connection or by modem. Also, always makes sure that you load DoubleVIEW from the DOS command prompt,and not from any shell or an application program's 'Go to DOS' mode. Run the installation program by placing the DoubleVIEW disk in Drive A, (or load the program file DBVDEMO.EXE onto your hard disk, if you prefer) and type: DBVDEMO ( press ) This will load the program as a 'TSR,' which you can hot-key into by pressing the keystroke combination ALT-V. (Again, this demonstration program will limit the number of times you can 'hot-key' back and forth into DoubleVIEW before you have to re-load the program.) Always makes sure that you load DoubleVIEW from the DOS command prompt,and not from any shell or an application program's 'Go to DOS' mode. Now press the hot-key combination Alt-V to activate DoubleVIEW (hold down the Alt key, and press V). DoubleVIEW will take over, the screen will clear, and you will be in DoubleVIEW's terminal mode. Setting Parameters From inside DoubleVIEW, press Alt-S. This will bring up the main Setup screen, which you will use to change DoubleVIEW's default settings to match your own SYSTEM's configuration. You can also use Setup for changing (for example) between a COM port and a modem, and for making other temporary changes. Take some time to scan through the different Setup screens by press- ing PgUp or PgDn seven times to look at the default setup config- uration, and the many options available. Press Home when you want to return to the first (main) Setup screen. (This screen is also called the Setup Directory.) From the Setup Directory, choose your Terminal Type. The terminal types supported are: VT100 VT200 SCO AT386 Wyse60 One of the terminal types listed will be highlighted (printed in reverse letters). This is the currently active terminal type. If you wish to emulate another terminal, use the left and right cursor control keys to move the high-lighted area over the terminal you desire. Notice how the screen blanks between changes; DoubleVIEW is re-configuring itself 'on-the-fly' to the terminal type highlighted. The individual Setup screens will also change for each Terminal Type chosen, so that only settings that apply to the chosen emulation will be displayed. Which Terminal Type Do I Want? Different Terminal Types (emulations) are necessary because each brand of terminal may have different screen formatting codes (Clear the Screen, Move the Cursor, etc.), different keyboard functions, and different printer support. DoubleVIEW knows how to make your PC system 'emulate' (look like) each brand of terminal to your Host. DoubleVIEW currently emulates the following terminal types: VT100 (and the VT101/VT102), VT200, SCO ANSI console, AT386 console, and Wyse60. VT-type printer support is provided for all emulations except WYSE60, including SCO and AT386 (which don't normally support printers). WYSE60 standard printer support is provided for the WYSE60 emulation. DoubleVIEW also supports color extensions for all emulations, even for those that do not normally support color. (You may disable this feature in the Color Setup screen.) If you are already using a certain terminal type included in the list of those supported, then that one would be your obvious choice. If you are new to terminals and multi-user computers, check to see what terminal types are supported by your host computer's operating system. Just as important, check to see what terminals are suggested (or required) by the multi-user applications you wish to use! If you have a System Administrator (the person in charge of maintain- ing a multi-user system), by all means ask him or her what terminal emulation you should select. If you are also going to be using DoubleVIEW to call up information services or bulletin boards, be aware that they may require different terminal types than your Host. That's where DoubleVIEW's Multiple Setup File feature will come in handy; you can easily set up a set of parameters (including terminal type) for each computer system you communicate with. DoubleVIEW Setup Now use Setup to change the rest of the communications settings you need in order to communicate with your host. Assuming you're still in Setup, press B to go to Communications. (You could also press a series of PgUps or PgDns to get to this screen.) Move the blinking cursor to the line 'Interface:', and then move it left or right to highlight the interface you will be using. The 'Internal' selection allows you to use DoubleVIEW with a standard serial port such as COM1 or COM2. The 'INT14' selection permits you to use DoubleVIEW with hardware that is supported with an INT 14h driver. For example, you could use an intelligent DigiBoard multi-channel serial card with it's DOS driver's INT 14h interface. Or, on Netware workstation you could use DoubleVIEW's INT 14h capabilities in conjunction with NVT (Netware Virtual Terminal) to access a UNIX host that is also on the network. Next, move the cursor to the line 'Comm Adapter:' , and then move it left or right to highlight the COM port you have your modem or serial cable connected to. If you are using the INT14 Interface, the COM1 - COM10 selections available for the INT14 Interface correspond to virtual port addresses 0-9. Select the Comm Adapter that matches the INT14 virtual address of the communications channel you are using. For example, if the communication channel you are using is assigned a virtual address of "2" by the INT 14h driver, you would select COM3 from the Comm Adapter selections. In a like manner, move the cursor to other lines and set your Parity, Bits per Char, and Baud Rate. Now press D to go to Keyboard Setup-D, the keyboard setup screen. Move the cursor down to Keyboard Type:, and select either PC/XT, AT or Enhanced,depending upon what type of keyboard you have connected to your PC. You'll also need to go to the Tabs setup screen and set the tab stops. (Every eight spaces is a good start.) Some UNIX full-screen editor programs like VI will not function without the tabs set. As you've certainly noticed, there are dozens of other settings that can be changed; we've just touched on the most vital ones. You can 'fine-tune' the rest of the settings at your leisure. (This demon- stration version won't let you save your settings to be loaded next time.) Going OnLine When you are done inspecting or changing the options in the Setup screens, press Esc to exit Setup and go to 'online' or terminal mode. You may return to Setup at any time (from within DoubleVIEW) by pressing Alt-S. You'll now be looking at a blank screen, with a status line on the bottom if you chose to display it. (You can make that choice in Setup A, by choosing 24 lines instead of 25. Most emulations default to 24.) Modem Users: If you are using a connection by modem, connect DoubleVIEW to your host computer by dialing the phone. If you have a Hayes compatible modem, you can have the modem dial the computer by entering an autodial command (see the example below). Check with your modem manual for details. Example (type something like this at your keyboard): AT DT 999-1234 DoubleVIEW will let you program the Autodial Key (or any of the twenty Softkeys) to type in a line like the above automatically. You should now be connected to your host computer. Press a few times to bring up a login message. Log-in as you would from any other terminal. When the host system asks for your terminal type, answer with the same type that you chose in Setup. (You'll have to get the exact spellings from your System Administrator, who can also set your default TERM type for you.) Run some host application programs that you're familiar with. Since your PC keyboard is not the same as the standard terminal's keyboard for the emulation you've chosen, you'll have to use some different keystrokes to represent keys (like high numbered VT-type function keys) that aren't on the PC keyboard. To help you find these 'replacement' keys on your PC keyboard, press the Alt-H key combination, and DoubleVIEW will show you a keytop chart for your particular emulation and PC keyboard type. When you are finished with your session, log-out in the normal fashion. Now exit DoubleVIEW by pressing Alt-V. DoubleVIEW will remain in memory and wait for another press of the hot-key Alt-V to start up again. Important! While using DoubleVIEW, do not enter commands from DOS that will access or alter the communications environment (like MODE COM1: 30,,,,p or the like). Also, do not hot-key into DoubleVIEW from inside another communications program! As you might expect, the communications settings for both will then become unpredictable. Press the Clear Comm key (F8) in Setup to reset the COM hardware if this happens. Here's a complete table of the Setup Screen key functions: Key Action ---------------------------------------------------------------- F1 Resets the terminal F2 Toggle between ONLINE and LOCAL mode. F3 Saves the current Setup configuration to the file- name listed on the line Setup File= on the first screen Setup Directory. F4 Restores the powerup (last) setup configuration. F7 Clear the terminal screen. F8 Clear the communications buffers. F10 Unload DoubleVIEW as a TSR program and exit to DOS. PgUp Go to the previous Setup screen. PgDn Go to the next Setup screen. Home Go to Setup Directory (first screen). End Go to the last Setup screen (Setup-I). Esc Leave Setup, go to ONLINE mode. If the Hot-Key Doesn't Work To minimize conflicts with other programs (especially important for a communications program), DoubleVIEW uses a keystroke-capture method that is sometimes screened out by application programs. Fortunately, most application programs sophisticated enough to screen out DoubleVIEW's keystroke capture usually also offer a DOS Shell (sometimes called a 'Go to DOS' mode). You may invoke the program's DOS Shell, and call up DoubleVIEW from there with the normal hot-key combination. Unloading DoubleVIEW DoubleVIEW may be unloaded from RAM (and its Hot-key deactivated) by pressing Alt-S to get into Setup, then pressing the Exit key, F10. This unloading will not take place if you have hot-keyed into DoubleVIEW from an application program; you must hot-key into DoubleVIEW from the DOS command line to unload DoubleVIEW. DoubleVIEW also cannot be unloaded unless it was the last TSR program loaded. Cut and Paste Cut and Paste is a DoubleVIEW feature that allows you to capture text from any text-mode screen (it doesn't matter if you're in DOS or UNIX) and paste that text into another DOS or UNIX appli- cation. (You can go from DOS to DOS, or from UNIX to UNIX, too.) The text is selected by highlighting it with the cursor keys. When you 'cut' text (actually copy it, as no text is destroyed), the characters are copied into a 1000-character paste buffer. When you switch applications to 'paste' the text elsewhere, the contents of the buffer are inserted into the keyboard buffer; this has the same effect as if you had typed in the information yourself. Here's how to use Cut and Paste: * Load DoubleVIEW. * Go to the application screen that you wish to cut text from, either by using DoubleVIEW to call up a UNIX application, or by using a DOS-based application. The only restriction is that the application must be in text (non-graphics) mode. * Press the Cut and Paste hot-key keystroke combination. (The default Cut and Paste Hot-key is Alt-P, but you can change this in Keyboard Setup-D. The rest of this section will assume that the hot-key is still Alt-P.) You will hear a beep, and the cursor will change to a square box. * Now move the cursor to one of the corners of the 'box' of text you wish to copy. * Press the Enter key to 'anchor' a box corner at this point. (If there was already text in the Cut and Paste buffer, you could paste it in now by pressing Alt-P again.) * Press the Enter key to anchor the box corner if you wish to capture just the text in the box you highlight, without any trailing spaces. If you're capturing something where the spaces are important (like a table), anchor the cursor with a Ctrl-Enter. * Now use the cursor keys again, to create a highlighted box over the text you want to copy. * When you have finished blocking out the text you want to copy, press the Enter key again (not Ctrl-Enter) to save the boxed text into the Paste buffer. * Pressing the Enter key will erase any previous information in the Cut and Paste buffer, and replace it with the text you just highlighted. If you wish to append the new text to text already in the buffer, press the plus key (+) instead of the Enter key after you have highlighted the text. * After you pressed either the Enter key or the + key, you are returned to the normal application you were in when you called Cut and Paste. * To Paste the text into another application (or even into the same one, of course), go to where you wish to paste the text, then press Alt-P to get into Cut and Paste mode. Now press Alt-P again to 'paste' your text into the new application. Experiment with the different effects you get with using the Enter anchor (no trailing spaces), the Ctrl-Enter anchor (trail- ing spaces), and the Enter capture (clear buffer) or + key capture (append to buffer). Cut and Paste Command Summary Keystroke Function ---------------------------------------------------------------- Alt-P Puts you in Cut and Paste mode. When already in Cut and Paste mode, Alt-P pastes whatever is in the buffer onto the screen. Enter Used to set the anchor for selecting text when you don't want trailing spaces captured in the block of text that you highlight. Once you've highlighted a block of text, Enter is also used to clear the Cut and Paste buffer and capture the text. (See + below.) Ctrl-Enter Used to set the anchor for selecting text when you want all trailing spaces captured in the block of text that you highlight. + Used to append a captured block of text to any text currently in the Cut and Paste buffer.
