FANSI-CONSOLE (tm) _____________ ____ Briefly, the program FANSI-CONSOLE (tm) is a fast ANSI X3.64 standard console driver for the IBM-PC, running under MS(PC)-DOS. The name "FANSI" comes from "fast ANSI". It is pronounced the same as "fancy". The "console" is what we call the screen and keyboard together. "MS(PC)-DOS" is the name we use for Microsoft's MS-DOS, of FANSI-CONSOLE _____________ which IBM-PC DOS is a variant. We also call FANSI-CONSOLE "The (tm) ____ Integrated Console Utility (tm)", because it integrates many little console control features into one program. FANSI-CONSOLE _____________ This chapter gives an overview of what FANSI-CONSOLE can do for you, and explains why you will want to use it. The next chapter tells you how to get started, so that you can try it right away. (C) Copyright 1984-85 Hersey Micro Consulting 1 (C) Copyright 1984-85 Hersey Micro Consulting 1 FANSI-CONSOLE Introduction _____________ FANSI-CONSOLE Introduction FANSI-CONSOLE _______________________________ 1.2 What does FANSI-CONSOLE do? 1.2.1 Compatibly replaces standard IBM-PC console software _____ __________ ________ ________ ______ _______ ________ 1.2.1 Compatibly replaces standard IBM-PC console software FANSI-CONSOLE _____________ FANSI-CONSOLE is both an MS(PC)-DOS console driver and a BIOS console driver. These are two somewhat similar but still different things. Somewhat like an actor playing the parts of both twins in a movie, FANSI-CONSOLE _____________ FANSI-CONSOLE plays the part of the standard IBM-PC ROM BIOS console code as well as the part of the standard IBM-PC MS(PC)-DOS console device driver (or the standard IBM-PC ANSI.SYS console device FANSI-CONSOLE _____________ driver). FANSI-CONSOLE replaces the screen and keyboard handling parts of both the IBM-PC ROM BIOS and the MS(PC)-DOS 2.00 (and later versions) operating system. It is a complete and compatible replacement for the standard IBM-PC console software, but offers many significant improvements. It also replaces many other small single feature console utilities which are available in the public domain and on the retail market. FANSI-CONSOLE _____________ Just like the operating system, FANSI-CONSOLE is always in memory FANSI-CONSOLE _____________ once it is placed there during the startup process. FANSI-CONSOLE ________ _____ __ __ __ __________ ______ requires about 20 KB of read/write memory for itself. In comparison, the standard IBM-PC ANSI.SYS device driver requires about 1.6 KB of FANSI-CONSOLE not _____________ ___ read/write memory for itself. FANSI-CONSOLE does not require any special hardware like a second diskette drive or a fixed disk. It performs just as well without them as with them. FANSI-CONSOLE _____________ FANSI-CONSOLE works on most computers which are hardware equivalent to the IBM-PC. These computers are sometimes called "compatibles" or "clones". Please note that because of the nature of the program, FANSI-CONSOLE _____________ ___ ___ FANSI-CONSOLE does not work on machines which are not hardware equivalent to the IBM-PC. For compatibility details please refer to the compatibility chapter contained within this manual. We obviously hope to extend the compatibility list, as more people report how well it works on other machines. (C) Copyright 1984-85 Hersey Micro Consulting 2 (C) Copyright 1984-85 Hersey Micro Consulting 2 FANSI-CONSOLE Introduction _____________ FANSI-CONSOLE Introduction 1.2.2 Speeds up screen writing _____ ______ __ ______ _______ 1.2.2 Speeds up screen writing FANSI-CONSOLE _____________ The most basic feature of FANSI-CONSOLE is that it speeds up the screen writing of many programs, including all MS(PC)-DOS internal commands. "Screen writing" is what we call the process of filling the screen with information by "writing" to it. Any program which uses standard MS(PC)-DOS or IBM-PC ROM BIOS calls to access the PC screen, instead of direct hardware manipulation, writes to the screen FANSI-CONSOLE __ ____ __ _____ _____ __ ____ _____________ as much as three times as fast as it does without FANSI-CONSOLE. Most of the speed ups that we have tested in our benchmarks range between 1.3 and 2.0 times as fast. Other programs, those which write directly to the IBM-PC screen memory, are unaffected. A program's FANSI-CONSOLE _____________ screen writing is never slowed down by FANSI-CONSOLE. This means much less waiting for menus and so on to be written onto your screen. Generally, programs that write to the screen slowly are the ones that are speeded up. Programs written to run on any MS(PC)-DOS machine are speeded up. Programs that are quick to begin with are nearly always the programs that write directly to the screen memory, and FANSI-CONSOLE ___ _____________ therefore are not affected by FANSI-CONSOLE. Also, any program that causes hashing (snow) on a standard IBM-PC color graphics display FANSI-CONSOLE _____________ adapter are not affected by FANSI-CONSOLE, because it writes directly to screen memory. For details about which programs are speeded up please refer to the compatibility list contained within the chapter entitled "Compatibility and Limitations". The amount of the speed up depends upon the type of display adapter used, the screen mode, what type of screen writing calls are used, whether scrolling is necessary, what brand of IBM-PC equivalent FANSI-CONSOLE _____________ machine you have, and whether FANSI-CONSOLE is replacing other single feature console utilities as well as the standard IBM-PC console software. Monochrome cards, and those color cards which do not require screen memory accesses to be delayed until a horizontal retrace, are generally speeded up more than the standard IBM-PC color graphics card. The alphanumeric screen modes generally are speeded up more than the graphics screen modes. DOS calls are generally speeded up more than BIOS calls. Programs that require no screen scrolling are speeded up more than those requiring scrolling. The best part is that the screen modes used the most, the alphanumeric modes with no scrolling, are speeded up the most. Some IBM-PC equivalent computer BIOSes are slower than others, and these are speeded up more than the fast ones. Most single feature console utilities have the bad side effect that they slow down the screen writing a bit. The more single feature console utilities you are FANSI-CONSOLE _____________ replacing with FANSI-CONSOLE, the more your screen writing will be speeded up. (C) Copyright 1984-85 Hersey Micro Consulting 3 (C) Copyright 1984-85 Hersey Micro Consulting 3 FANSI-CONSOLE Introduction _____________ FANSI-CONSOLE Introduction 1.2.3 Processes more ANSI X3.64 escape sequences _____ _________ ____ ____ _____ ______ _________ 1.2.3 Processes more ANSI X3.64 escape sequences FANSI-CONSOLE _____________ Another important feature is that FANSI-CONSOLE processes American National Standards Institute (ANSI) X3.64 standard escape sequences like the standard IBM-PC DOS 2.00 (and later versions) ANSI.SYS device driver. This standard is a subset of the International FANSI-CONSOLE _____________ ______ _ Standards Organization's standard ISO 6429. FANSI-CONSOLE allows a ____ ______ ______ __ ___ ________ much larger subset of the standard to be used than the standard IBM-PC ANSI.SYS device driver does. All escape sequences work in the graphics screen modes as well as in the alphanumeric screen modes. This means programs can do more versatile things with the screen in a simpler and computer independent way. This is directly important to you because such programs can have their screen output sent to remote terminals, or be redirected to data files. Indirectly, it is important to you, because it may have the effect of reducing program development costs by making it easier to write things to the screen and by allowing the same program to run without change on many different types of computers. Presumably, the program developers will pass the savings on to you. For more details, see the chapter entitled "ANSI X3.64 escape sequences". Please note that the chapter abbreviated ___________ describing these escape sequences is not in the abbreviated user manual found on the diskette, but is contained in the complete printed user manual. A few demonstration files are included on the diskette, though. Using these escape sequences it is possible to limit the screen output of some programs to a portion of the screen called a "window" or a "scrolling region". These windows can be scrolled in any direction or otherwise modified without affecting text on the rest of the screen. A program which knows about scrolling regions may use more than one scrolling region to effectively divide the screen display. For more details, see the description of the ANSI SSR command in the chapter entitled "ANSI X3.64 escape sequences". Please note that the chapter describing these escape sequences is not abbreviated ___________ in the abbreviated user manual found on the diskette, but is contained in the complete printed user manual. A few files are included on the diskette which give demos, though. (C) Copyright 1984-85 Hersey Micro Consulting 4 (C) Copyright 1984-85 Hersey Micro Consulting 4 FANSI-CONSOLE Introduction _____________ FANSI-CONSOLE Introduction 1.2.4 Emulates DEC VT100 _____ ________ ___ _____ 1.2.4 Emulates DEC VT100 FANSI-CONSOLE _____________ FANSI-CONSOLE can make the numeric keypad and function keys emulate a DEC VT100 auxiliary keypad. With the processing of ANSI X3.64 escape sequences, this can make the IBM-PC console look like a DEC VT100 to any application program. This is useful because there are already many good programs written for machines that use the VT100 for a console. The console handling of such programs do not have to be rewritten to allow them to run on an IBM-PC. It also means that simple terminal emulation (communications) programs which use MS-DOS MODEM86 (tm) _______ ____ console calls, such as our MODEM86 (tm) program, turns your IBM-PC or equivalent into an ANSI X3.64 standard terminal. For more details, FANSI-CONSOLE _____________ see the section entitled "How do I get FANSI-CONSOLE to emulate a VT100?" in the chapter entitled "Advanced Features". FANSI-CONSOLE _____________ FANSI-CONSOLE can also emulate a DEC VT52/Heath H19/Zenith Z100 console as part of its VT100 emulation. For more details about getting into this mode, see the subsection describing the ANSI DEC-SM command in the chapter entitled "ANSI X3.64 escape sequences". 1.2.5 Allows one finger pausing _____ ______ ___ ______ _______ 1.2.5 Allows one finger pausing FANSI-CONSOLE _____________ ______ ___ __ ___ __ ___ ___________ ___ ___ ________ FANSI-CONSOLE allows you to set up the Scroll-Lock key for optional ___ ______ _______ one finger pausing. The Scroll-Lock key may be set up to act as a scroll lock toggle, somewhat similar to the Ctrl-Num-Lock combination you are already familiar with. However, it allows you to typeahead before turning off the scroll lock. With both the Ctrl-Num-Lock and FANSI-CONSOLE _____________ Scroll-Lock pausing, FANSI-CONSOLE prevents the duplicate lines which may appear when using the standard IBM-PC software. For more details, see the chapter entitled "Detailed Installation". 1.2.6 Allows recall of lines scrolled off the screen _____ ______ ______ __ _____ ________ ___ ___ ______ 1.2.6 Allows recall of lines scrolled off the screen FANSI-CONSOLE _____________ Another important optional feature of FANSI-CONSOLE is that when you pause with Scroll-Lock, it allows you to scroll backward, and forward again, to see lines which have already left the top of the screen. Such lines would otherwise be gone for good. Now you can even print them. We call this the scroll recall feature. For more details, see the chapter entitled "Detailed Installation" and the section entitled "How do I use the scroll recall feature?" in the chapter entitled "Advanced Features". Please note the latter section is not in the abbreviated ___________ abbreviated user manual found on the diskette, but is contained in the complete printed user manual. (C) Copyright 1984-85 Hersey Micro Consulting 5 (C) Copyright 1984-85 Hersey Micro Consulting 5 FANSI-CONSOLE Introduction _____________ FANSI-CONSOLE Introduction 1.2.7 Allows much more typeahead _____ ______ ____ ____ _________ 1.2.7 Allows much more typeahead FANSI-CONSOLE _____________ FANSI-CONSOLE has a much larger typeahead buffer than the standard IBM-PC typeahead buffer. Typeahead is what your keystrokes are called when the currently running program is not reading them at the moment. Sometimes the program is busy with a previous command. FANSI- ______ Other times the program just does not require keyboard input. FANSI- CONSOLE _______ CONSOLE allows 127 characters of typeahead. The standard IBM-PC typeahead buffer allows only 15 characters. This means you are much less likely to get that horrible beep that means your keystrokes are being ignored because the currently running program is busy. Because the convenience of so much typeahead also brings problems of FANSI-CONSOLE _____________ discovering that you mistyped something early on, FANSI-CONSOLE also _____ ___ _________ ______ allows you to flush the typeahead buffer with a Ctrl-F without stopping what is currently running. Also Ctrl-C, Ctrl-Break, and Ctrl-S, all flush the typeahead buffer before their normal action. This means you will not be ignored when you type these keys just because you happened to have typed ahead something else earlier. For FANSI- ______ more details, see the section entitled "How do I use the FANSI- CONSOLE _______ CONSOLE keyboard?". 1.2.8 Allows keyboard macro assignment during running programs _____ ______ ________ _____ __________ ______ _______ ________ 1.2.8 Allows keyboard macro assignment during running programs FANSI-CONSOLE _____________ Unlike the standard IBM-PC ANSI.SYS program, FANSI-CONSOLE allows you to assign keyboard macros to a key even during a running program. A keyboard macro is a string of characters you assign to a particular key so that by pressing that key, you can automatically input a whole string of characters. Using keyboard macros avoids the tedium of typing the same long string of characters more than once. For more FANSI- ______ details, see section entitled "How do I assign macros to FANSI- CONSOLE _______ CONSOLE keys?" in the chapter entitled "Advanced Features". Please abbreviated ___________ note this chapter is not in the abbreviated user manual found on the diskette, but is contained in the complete printed user manual. 1.2.9 Allows more memory for keyboard macros _____ ______ ____ ______ ___ ________ ______ 1.2.9 Allows more memory for keyboard macros More memory is allowed for keyboard macros than the standard IBM-PC FANSI-CONSOLE _____________ ANSI.SYS device driver. FANSI-CONSOLE also allows you to specify how much memory is used for keyboard macros. For more details, see the chapter entitled "Detailed Installation". (C) Copyright 1984-85 Hersey Micro Consulting 6 (C) Copyright 1984-85 Hersey Micro Consulting 6 FANSI-CONSOLE Introduction _____________ FANSI-CONSOLE Introduction 1.2.10 Turns displays off when not in use ______ _____ ________ ___ ____ ___ __ ___ 1.2.10 Turns displays off when not in use FANSI-CONSOLE _____________ For most display adapters, FANSI-CONSOLE can be configured to automatically turn off your console screen displays when not in use for a specified time. This helps prevent you from permanently burning a particular display pattern into the phosphors on your FANSI-CONSOLE _____________ screen by leaving it on the display too long. FANSI-CONSOLE will turn off both displays, if you have two display adapters. Please note that to avoid surprising people, this is not the default action. For more details, see the chapter entitled "Detailed Installation". 1.2.11 Allows one finger typing ______ ______ ___ ______ ______ 1.2.11 Allows one finger typing FANSI-CONSOLE _____________ ______ ___ __ ___ __ ___ ________ ___ ________ FANSI-CONSOLE allows you to set up the keyboard for optional __________ ______ one-finger typing for the physically handicapped. Combined with the one-finger pausing and scroll recall, the console becomes a much more FANSI-CONSOLE _____________ convenient tool for the physically handicapped when FANSI-CONSOLE is used. For more details, see the chapter entitled "Detailed Installation". 1.2.12 Allows keyboard generated breakpoints ______ ______ ________ _________ ___________ 1.2.12 Allows keyboard generated breakpoints FANSI-CONSOLE _____________ FANSI-CONSOLE has Alt-Ctrl-Ins set up to generate the equivalent of a breakpoint. This is handy for assembly language programmers, when debugging programs with infinite loops.

(C) Copyright 1984-85 Hersey Micro Consulting 8 (C) Copyright 1984-85 Hersey Micro Consulting 8 FANSI-CONSOLE Introduction _____________ FANSI-CONSOLE Introduction FANSI-CONSOLE _________________________________________________________________ 1.3 What about multitasking windowing programs and FANSI-CONSOLE? FANSI-CONSOLE _____________ You may wonder how FANSI-CONSOLE compares with some of the new multitasking windowing programs such as IBM's TopView, Quarterdeck's FANSI-CONSOLE _____________ DESQ, or Microsoft's Windows. FANSI-CONSOLE is not meant to compete directly with these programs. Such programs are called "multitasking" because they allow several programs to be in the middle of doing their respective "tasks" at the same time. A multitasking windowing program manages the screen for such tasks, and allows you to switch between tasks. We want to make it clear that FANSI-CONSOLE FANSI-CONSOLE _____________ _____________ FANSI-CONSOLE does not handle multitasking. FANSI-CONSOLE may be FANSI-CONSOLE _____________ used with most multitasking windowing programs. FANSI-CONSOLE may not affect them or the programs running under them, since most of these multitasking windowing programs write directly to the screen hardware. There will be times, though, when you will want to run without the multitasking windowing program, to do things like run batch files or programs with command line parameters. At these FANSI-CONSOLE _____________ times, FANSI-CONSOLE will be there to speed up screen access. FANSI-CONSOLE _____________ We believe that FANSI-CONSOLE is generally a more helpful product for the budget minded customer than multitasking windowing programs. FANSI-CONSOLE _____________ FANSI-CONSOLE offers much less in the way of features than most FANSI-CONSOLE _____________ multitasking windowing programs, but FANSI-CONSOLE uses much less read/write memory and no secondary memory like additional disks, and costs less than most multitasking windowing programs. Multitasking windowing programs usually need much more than 256K and a fixed disk for quick execution or sometimes any execution! All this memory is generally used to keep several programs in memory at once as well as copies of their screen displays. Requiring that much memory or fixed disks means that those of you who cannot afford to lay out so much money per system are unable to use multitasking windowing programs. Even if you can afford a multitasking windowing program and its FANSI-CONSOLE _____________ required extra hardware, you may find FANSI-CONSOLE more to your FANSI-CONSOLE _____________ liking. FANSI-CONSOLE speeds up the screen writing of many programs to make them quick enough for your tastes. When your favorite FANSI-CONSOLE _____________ application program still takes awhile to do something, FANSI-CONSOLE allows you to keep typing by having a generous typeahead buffer. Most multitasking windowing products do nothing to speed up the screen writing of other programs. They also do not allow you to typeahead much. Many slow things down, even though they claim to be "user-friendly". However, it is generally recognized that being speedy is the most user-friendly quality of a product.

You only have to know what is in this ______ chapter to get started. If you want really brief instructions, just ____ read the description of this chapter in the table of contents! We know how much you hate to have to read the manual before trying out a program. Unfortunately, this program can not be menu driven because of its nature. There is an extensive index at the end of this manual. It is there to help you if you have problems finding what you want to know. Please use it, especially if you do not read the manual from cover to cover. For example, solutions to many common problems can be found by looking up the keyword "problem" in the index. If you can not find something where you looked first in the index, let us know! We think the index should be comprehensive. That minimizes the number of calls we get asking about things which are fully explained in the manual but hard to find. If you can not find what you want to know in the abbreviated user manual found on the diskette, then it is probably time to order a complete printed user manual. You can tell this is the case when you find yourself looking for a page number mentioned in the index or table of contents that is not in your abbreviated user manual.

Start out by making sure the distribution diskette is write protected, so you do not accidentally destroy what __ ____ is on it by copying to it instead of copying from it. After all, the reason you should make the backup copy in the first place is to have extra copies if one copy gets accidentally destroyed. 2.2.3 Backup system disks _____ ______ ______ _____ 2.2.3 Backup system disks The third step is to make backup copies of your MS(PC)-DOS 2.00 (or later versions) system diskettes using the MS(PC)-DOS DISKCOPY command, as outlined in the MS(PC)-DOS manual. A system disk is any disk with the MS(PC)-DOS operating system on it. Many MS(PC)-DOS ___ diskettes are NOT system disks. The best way to tell if a diskette is a system disk is to put the diskette into drive A: and restart MS(PC)-DOS by pressing Alt-Ctrl-Del. If MS(PC)-DOS starts without further changing diskettes, then the diskette is a system disk. If you have a fixed disk and you can start MS(PC)-DOS using Alt-Ctrl-Del without a diskette in drive A:, then your fixed disk is also a system disk. However, it is not necessary to make a backup copy of your FANSI-CONSOLE _____________ fixed disk just to try FANSI-CONSOLE. If your MS(PC)-DOS version is less than 2.00, then run out and buy FANSI-CONSOLE _____________ the latest version now! FANSI-CONSOLE requires at least version 2.00. Many other programs soon will as well. Do not get lost in the past! 2.2.4 Copy FCONSOLE.DEV to system disk _____ ____ ____________ __ ______ ____ 2.2.4 Copy FCONSOLE.DEV to system disk The fourth step is to copy the file FCONSOLE.DEV from our distribution diskette to your MS(PC)-DOS 2.00 (or later) system disks using the MS(PC)-DOS COPY command. Copy FCONSOLE.DEV to the root directory on the system disk. Do this to all your system disks, if you have more than one. However, we suggest that you do them one at a time. Test each one for a few days, or a time period comfortable for you, before installing it on other system disks. If you have a fixed disk, we suggest you try this on a diskette first before FANSI-CONSOLE _____________ installing FANSI-CONSOLE on the fixed disk. All this caution is FANSI-CONSOLE _____________ merely to allow you to start your system without FANSI-CONSOLE if there are some problems with it on your system. (C) Copyright 1984-85 Hersey Micro Consulting 14 (C) Copyright 1984-85 Hersey Micro Consulting 14 FANSI-CONSOLE Starting Quickly _____________ FANSI-CONSOLE Starting Quickly 2.2.5 Add DEVICE=FCONSOLE.DEV to CONFIG.SYS _____ ___ ___________________ __ __________ 2.2.5 Add DEVICE=FCONSOLE.DEV to CONFIG.SYS The fifth step is to add the line: DEVICE=FCONSOLE.DEV DEVICE=FCONSOLE.DEV to the beginning of the CONFIG.SYS file on your system disk, in the root directory. If there is a CONFIG.SYS file in the root directory on your system disk when you start MS(PC)-DOS, MS(PC)-DOS will read it for special instructions. This is a special instruction to FANSI-CONSOLE _____________ MS(PC)-DOS to install FANSI-CONSOLE when MS(PC)-DOS starts up. You must create the CONFIG.SYS file if there is not already one in the root directory on the system disk. Your favorite editor may be used to do this. It is important that the line be at the start of the CONFIG.SYS file instead of the middle or the end. This is mostly FANSI-CONSOLE _____________ because the sooner FANSI-CONSOLE gets loaded and its name banner is displayed, the sooner your larger typeahead buffer is ready to be FANSI-CONSOLE _____________ used. It is also important that FANSI-CONSOLE be loaded before any other device drivers that require keyboard or screen handling, such as mouse device drivers. Otherwise, the position of this line does not matter. The letters may be either upper or lower case. It is important that the "DEVICE=FCONSOLE.DEV" line is ended with a carriage return, and not just with the end of the CONFIG.SYS file. _______ There is a bug in MS(PC)-DOS 2.0 which causes such a line without the carriage return to yield the following strange looking message: Bad or missing FCONSOLE.DEVLE.DEV Bad or missing FCONSOLE.DEVLE.DEV The repeated part of the name is really in the message. This bug was fixed in MS(PC)-DOS 3.0. (C) Copyright 1984-85 Hersey Micro Consulting 15 (C) Copyright 1984-85 Hersey Micro Consulting 15 FANSI-CONSOLE Starting Quickly _____________ FANSI-CONSOLE Starting Quickly 2.2.6 Remove DEVICE=ANSI.SYS from CONFIG.SYS _____ ______ _______________ ____ __________ 2.2.6 Remove DEVICE=ANSI.SYS from CONFIG.SYS The sixth step is to delete any lines like: DEVICE=ANSI.SYS DEVICE=ANSI.SYS from the CONFIG.SYS file. If you have a reference to another console driver, such as the IBM-PC ANSI.SYS device driver, in the CONFIG.SYS FANSI-CONSOLE _____________ file then you should remove it. This is because FANSI-CONSOLE is a direct replacement for ANSI.SYS as well as the part of the standard IBM-PC ROM BIOS that deals with the console. They both have the name "CON:" when referred to later with other MS(PC)-DOS commands. They cannot coexist and there is no point in trying to make them coexist FANSI-CONSOLE _____________ because FANSI-CONSOLE has all the function of the ANSI.SYS device driver. Please note that it is only console drivers that do not work with FANSI-CONSOLE _____________ FANSI-CONSOLE. Device drivers for devices other than the console FANSI-CONSOLE _____________ (CON:) may be used with FANSI-CONSOLE. Such drivers include FANSI- ______ read/write memory-based diskette emulators (RAM-disk) like FANSI- RAMDISK (tm) _______ ____ RAMDISK (tm) and mouse device drivers. So most lines which start with: DEVICE= DEVICE= do not need to be deleted from CONFIG.SYS. If you happen to load both console drivers, the one which is loaded last is the one that will really be used as the MS(PC)-DOS console driver. It has either of two bad effects, depending upon which driver is specified first in CONFIG.SYS. If ANSI.SYS is loaded FANSI- ______ first, memory is consumed by ANSI.SYS to no effect, since FANSI- CONSOLE FANSI-CONSOLE _______ _____________ CONSOLE is used instead of ANSI.SYS. If FANSI-CONSOLE is loaded first, it does not work (unless /Y=1, see the chapter entitled "Detailed Installation"). In this case, ANSI.SYS is used as the MS(PC)-DOS console driver. ANSI.SYS directly modifies ROM BIOS code variables (a bad programming practice) and then calls the BIOS expecting those variables to have some effect. However, the BIOS FANSI-CONSOLE _____________ calls are now calls to FANSI-CONSOLE, which does not use variables in the same place in memory as ANSI.SYS expected.

Now that you have changed your CONFIG.SYS file, all you do is use that system disk when you turn on the computer or when you press the Alt-Ctrl-Del key combination. Of course, you could have several system disks with both FCONSOLE.DEV and CONFIG.SYS on it and any one of them will do. ___ You do not need to have these files on an available disk drive after FANSI- ______ the MS(PC)-DOS operating system is loaded at the start. FANSI- CONSOLE _______ CONSOLE remains loaded in memory as part of the MS(PC)-DOS operating system until the next time you restart the system. FANSI-CONSOLE _____________ You will know FANSI-CONSOLE is installed when you see the single line banner with the name of the program and our copyright message at the top of your screen when you start. If you do not see the banner when FANSI-CONSOLE _____________ you start, you will know FANSI-CONSOLE is not installed. It is as simple as that! In either case, you will see the old familiar MS(PC)-DOS prompt. Notice that we do not beat you over the head with a full screen request for payment of the usage royalty, like some programs do. We just do that in the user manual!

It is not important to place this line in any particular place in the CONFIG.SYS file. The purpose of this command is to allow more buffer space for MS(PC)-DOS to use for reading and writing files. Although this has FANSI-CONSOLE _____________ nothing to do with FANSI-CONSOLE, it also speeds up your computer by speeding up your disk accesses. We mention it here because many people are unaware of it. The only negative aspect to using this line in your CONFIG.SYS file is that it consumes about 10 KB of read/write memory for extra buffer space which is no longer available for your application programs. However, you may replace the number 20 with a smaller number, even one as small as 5. It still speeds up your system, although not as much. The space required is proportional to the number used. Using a larger number may help more if you have a large or full hard disk. If the number is too large, it starts slowing the computer down again. Only you can find the best number for your system, but almost any number is better than the 2 you get by default. (C) Copyright 1984-85 Hersey Micro Consulting 18 (C) Copyright 1984-85 Hersey Micro Consulting 18 FANSI-CONSOLE Starting Quickly _____________ FANSI-CONSOLE Starting Quickly 2.2.9 Modify Prompt _____ ______ ______ 2.2.9 Modify Prompt Although it is not necessary, you may want to add something like the following line to the AUTOEXEC.BAT file on your system disk: PROMPT $e[2;37;40m$e[J$n$g PROMPT $e[2;37;40m$e[J$n$g Note that upper and lower case letters must be used exactly as indicated in the prompt. This is a MS(PC)-DOS internal command that describes the prompt that MS(PC)-DOS should use when it is ready for a new command. In this case, we have it send out an ANSI X3.64 SGR escape sequence (indicated by the "$e[2;37;40m") to set the current screen colors and other attributes to the normal values before displaying the current drive letter ($n) and a greater than symbol ($g). We also send out an ANSI X3.64 erase in display escape sequence ($e[J) to erase the rest of the screen in the current colors. We recommend this because some programs leave the current screen color attributes in undesired states. If the screen erasing is not done, you may find that even though what you type is the right color, and the rest of the screen is black, the cursor is a different color. However, using a prompt like this does have some small side effects, which you should note. 1. The PROMPT only resets the foreground and background colors after every MS(PC)-DOS command, when the MS(PC)-DOS ECHO is ON. If ECHO is OFF, it has no effect. 2. The PROMPT resets the foreground and background colors after _____ every MS(PC)-DOS command, when the MS(PC)-DOS ECHO is on. This means that you will not be able to change the colors without changing the PROMPT, since it will reset them again immediately afterwards. So you may want to experiment with different ______ colors before setting up this PROMPT. 3. MS(PC)-DOS is apparently counting the prompt characters, except the escape. When you use this prompt and you type the line-delete character (ESC for PC-DOS and Ctrl-X for MS-DOS) to restart a line that you are typing at the MS(PC)-DOS prompt, MS(PC)-DOS spaces over too far for the new line. It does not realize that these prompt characters do not all really appear on the screen. (C) Copyright 1984-85 Hersey Micro Consulting 19 (C) Copyright 1984-85 Hersey Micro Consulting 19 FANSI-CONSOLE Starting Quickly _____________ FANSI-CONSOLE Starting Quickly 4. When you use this prompt and you type the echo-console-onto-printer character (Ctrl-PrtSc for PC-DOS and Ctrl-P for MS-DOS), prompts do not appear the same as they do on the screen. This is because your printer does not understand ANSI X3.64 escape sequences. 5. When you include an erase in display command as part of your prompt, there will be a small delay while the erasing is done before the printed part of your prompt appears. The closer the prompt is to the top of the display, the longer the delay. This is more noticeable with some display adapters (those requiring the /H=1 option) than others. You may find a different set of colors or attributes desirable. You may also want the MS(PC)-DOS prompt to use different colors or have different attributes than what you type after it. So you may want to use different ANSI X3.64 SGR commands, like the following: PROMPT $e[2;32;40m$e[J$e[1;36m$n$g$e[2;32m PROMPT $e[2;32;40m$e[J$e[1;36m$n$g$e[2;32m (C) Copyright 1984-85 Hersey Micro Consulting 20 (C) Copyright 1984-85 Hersey Micro Consulting 20 FANSI-CONSOLE Starting Quickly _____________ FANSI-CONSOLE Starting Quickly 2.2.10 Provide memory for applications programs ______ _______ ______ ___ ____________ ________ 2.2.10 Provide memory for applications programs FANSI-CONSOLE _____________ Although, FANSI-CONSOLE does not require much memory for itself, it does require some. If you have made ram-disks or print spoolers consume all the extra memory you had before, then you need to adjust these programs to use a bit less. You need to have about the same amount of memory left over for applications programs as you did before. Otherwise programs will run out of room because you have left too little for them. Sometimes a program will not complain directly about having less memory, instead it may start doing more disk accesses than before. It may do this either to load and reload overlays or to spill large amounts of data into and out of a temporary disk file. This even happens on computers fully loaded with memory. Remember, what counts is not the total memory you have, but how much of it you have left for the applications programs. To find out how much memory is left over for applications programs, use the MS(PC)-DOS CHKDSK command. The last line printed is the amount of memory usable by applications programs. We can not tell you exactly how much you will need, since it depends on what programs you run. However, nearly everyone should leave at least 128 KB. (C) Copyright 1984-85 Hersey Micro Consulting 21 (C) Copyright 1984-85 Hersey Micro Consulting 21 FANSI-CONSOLE Starting Quickly _____________ FANSI-CONSOLE Starting Quickly FANSI-CONSOLE _______________________________ 2.3 How do I use FANSI-CONSOLE? FANSI-CONSOLE _____________ Now that you have FANSI-CONSOLE installed, you just proceed as you FANSI-CONSOLE _____________ always do, and mostly ignore the fact that FANSI-CONSOLE is loaded FANSI-CONSOLE _____________ and running. When the FANSI-CONSOLE banner appears at the top of your screen when you start MS(PC)-DOS, many programs magically paint the screen faster without your further intervention. All that is necessary for you to do now is to appreciate our efforts! As noted before, you may want to use the typeahead buffer more than before. You may also want to take advantage of the new special keys described here. Some more useful features are described in the chapters entitled "Detailed Installation" and "Advanced Features", but you do not need to rush to those chapters yet. 2.3.1 Using the Ctrl-F key Press the Ctrl-F key to simply flush (empty) the typeahead buffer. The Ctrl-F is left in the buffer, but many programs ignore it or do something harmless. If you find an application that does something dangerous with the Ctrl-F key, you may want to try the Ctrl-S key instead. 2.3.2 Using the Ctrl-S key Press the Ctrl-S key to flush the typeahead buffer and, if the current program uses Ctrl-S as a pause key, cause the current program to pause. Most programs pay attention to this key and pause. Otherwise they probably ignore it. The standard IBM-PC software processes the Ctrl-S slightly differently, by not flushing the typeahead buffer when a Ctrl-S is pressed. This means that the standard IBM-PC software ignores the Ctrl-S character if you already have some characters in the typeahead buffer. For other ways to pause, see the description of the Ctrl-Num-Lock key in the next paragraph and of the /L=1 option in the chapter entitled "Detailed Installation". (C) Copyright 1984-85 Hersey Micro Consulting 22 (C) Copyright 1984-85 Hersey Micro Consulting 22 FANSI-CONSOLE Starting Quickly _____________ FANSI-CONSOLE Starting Quickly 2.3.3 Using the Ctrl-Num-Lock key Press the Ctrl-Num-Lock key to cause the display to pause without FANSI-CONSOLE _____________ flushing the typeahead buffer. With FANSI-CONSOLE this key combination works in a manner similar to the way it works with the standard IBM-PC software. One advantage, however, is that unlike the FANSI-CONSOLE _____________ standard IBM-PC software, FANSI-CONSOLE prevents the appearance of duplicate lines during a pause. Press any other key combination to unlock the pause. Unless the second key combination is a Ctrl-Break or a Ctrl-C, it is ignored other than for clearing the pause. Any FANSI-CONSOLE _____________ program that works with FANSI-CONSOLE pauses with Ctrl-Num-Lock. For other ways to pause, see the description of the Ctrl-S in the previous paragraph and of the /L=1 option in the chapter entitled "Detailed Installation". 2.3.4 Using the Ctrl-C or Ctrl-Break keys Press the Ctrl-C key to cancel most programs. It is treated by FANSI-CONSOLE _____________ FANSI-CONSOLE as equivalent to the Ctrl-Break key. Both keys are treated the same way as the standard IBM-PC software treats the Ctrl-Break key, which is to flush the typeahead buffer before placing a Ctrl-C in it. The standard IBM-PC software processes the Ctrl-C slightly differently, by not flushing the typeahead buffer when a Ctrl-C is pressed. This means that the standard IBM-PC software ignores the standard MS(PC)-DOS Ctrl-C cancel character when you already have some characters in the typeahead buffer. Pressing Ctrl-C does not cancel any program that Ctrl-Break does not cancel when using the standard IBM-PC software. 2.3.5 Using the Ctrl-Equals key Press the Ctrl-Equals key combination, instead of the Ctrl-6 key combination used by the standard IBM-PC software, to get a Unit Separator (US) character. Wherever any application program specifies the use of the Ctrl-6 key combination in its user manual, use FANSI-CONSOLE _____________ Ctrl-Equals instead when FANSI-CONSOLE is installed. This is the FANSI-CONSOLE _____________ only character whose key combination is different with FANSI-CONSOLE than with the standard IBM-PC software. This character was placed at a different key to free a whole row of keys (Ctrl-1 thru Ctrl-0) for FANSI-CONSOLE _____________ later use by FANSI-CONSOLE.

If you ever find that you need to use another application program FANSI-CONSOLE _____________ without having FANSI-CONSOLE installed, because of incompatibility or other reasons, it is just as easy to uninstall as it is to install. The easiest way is to start your system using a system disk on which FANSI-CONSOLE _____________ FANSI-CONSOLE is not installed. Another way is to simply remove the "DEVICE=FCONSOLE.DEV" line from the CONFIG.SYS file on your normal system disk. If it is the only FANSI-CONSOLE _____________ line in CONFIG.SYS, then FANSI-CONSOLE may also be uninstalled by deleting or renaming CONFIG.SYS to another name like CONFIG.TMP. Once the line is removed from CONFIG.SYS, or CONFIG.SYS is removed or renamed, you must restart your computer. This may be done by pressing Alt-Ctrl-Del or by turning your computer off and then on. Simply removing the FCONSOLE.DEV file from your system disk, or FANSI- ______ renaming it, and restarting your computer also uninstalls FANSI- CONSOLE _______ CONSOLE, but it causes the following error message to be displayed by MS(PC)-DOS when you start your computer: Bad or missing FCONSOLE.DEV Bad or missing FCONSOLE.DEV FANSI-CONSOLE _____________ If you are uninstalling FANSI-CONSOLE, and you have set your MS(PC)-DOS prompt to use ANSI X3.64 escape sequences codes, you will probably want to replace the "DEVICE=FCONSOLE.DEV" line in the CONFIG.SYS file with a line containing "DEVICE=ANSI.SYS", or at least change your prompt again.

Now we describe some features of MS(PC)-DOS that are not well described in the IBM-PC DOS manuals. Some but not all the features __ are in the manuals. What is in the manuals is definitely hard to find. IBM has even moved most of this information to a separately purchased manual called the DOS Technical Reference Manual. We feel FANSI-CONSOLE _____________ it is useful for you to know this to understand what FANSI-CONSOLE is and how it works. MS(PC)-DOS has provision for people other than IBM or Microsoft to write something called a "loadable device driver". A loadable device driver is Microsoft's excellent answer to the problems that many IBM-PC compatible add-on hardware manufactures had with DOS 1.xx. The problem was that to make a new piece of hardware work in your system as though it was really an integral part of the original IBM-PC and IBM-PC DOS, the add-on manufacturers had to create software for their cards and make it look like part of the original IBM-PC DOS. However, they were not given the source program code for MS(PC)-DOS, nor were they given a standard way to write their software and have MS(PC)-DOS include this code into itself as it started up. So everyone started disassembling the operating system and making some very ugly programs that patched themselves into the operating system in whatever ways they could figure out. The result was that choosing two of these programs for two different pieces of add-on hardware would almost invariably cause conflicts and they would not work together. Furthermore, the programs would not work with newer versions of MS(PC)-DOS, if for no other reason than that the MS(PC)-DOS internal program variable addresses would change. (C) Copyright 1984-85 Hersey Micro Consulting 25 (C) Copyright 1984-85 Hersey Micro Consulting 25 FANSI-CONSOLE Detailed Installation _____________ FANSI-CONSOLE Detailed Installation Microsoft's solution was to allow add-on hardware manufacturers to write programs called loadable device drivers to control their hardware ("drive their devices") by following a standard form which Microsoft specified. These device drivers are then loaded at start up time similarly to the original device drivers that come with MS(PC)-DOS from your original manufacturer (IBM or your equivalent maker). This is a new feature of MS(PC)-DOS 2.00 and later versions. Now all the add-on hardware manufacturers have to do is to give you a driver program in a regular MS(PC)-DOS file, and tell you how to include it in your operating system as you start up. IBM even provides two loadable device drivers themselves. One is a console driver called ANSI.SYS and was provided in object form. The other was a read/write memory based disk emulation (ram-disk) which was provided as a listing (source form) in the MS(PC)-DOS manual for version 2.0. In version 3.0 they included a similar program in object form called VDISK.SYS. Besides allowing the add-on hardware manufacturers to create driver programs for their hardware, the loadable device drivers can also be used to change the behavior of devices which are already supported by FANSI-CONSOLE _____________ MS(PC)-DOS. That is exactly what FANSI-CONSOLE is all about! The best part is how you incorporate loadable device drivers into MS(PC)-DOS. All you have to do is create a file called CONFIG.SYS with a few commands in it. MS(PC)-DOS always read this file, if there is one on your system disk, when it starts and it executes these commands before it does anything else. It does this even before doing the AUTOEXEC.BAT file. Because of the nature of these commands, they may only be done in the CONFIG.SYS file and nowhere else. The command to load a loadable device driver is: DEVICE=<driver file name> <options> DEVICE=<driver file name> <options> The <driver file name> part is the MS(PC)-DOS file name of the device driver. If the driver is in a directory other than the root directory, the complete path name must be used. What the <options> part looks like is entirely up to your device driver authors (that's us!). So it looks like whatever they decide. It may look different for different device drivers. Often <options> are unnecessary. The order of the DEVICE commands determines which is loaded first. If two drivers have the same name, like CON: which is the name of the MS(PC)-DOS console driver, the one which is loaded last is the one used.

FANSI-CONSOLE _____________ FANSI-CONSOLE has many installation options. They all have default FANSI-CONSOLE _____________ values which are set so that FANSI-CONSOLE is as similar to the standard IBM-PC console software as possible. This means, for example, that the options which require hardware dependent values, have defaults that match the needs of the standard IBM-PC display FANSI-CONSOLE _____________ adapter cards. So, by default, FANSI-CONSOLE should work on all "equivalent" computers and adapter cards. However, if you do not FANSI-CONSOLE _____________ have a standard IBM-PC display adapter card, FANSI-CONSOLE will ______ probably work better if the option values are changed. Also, many of the options are used to select behavior which is more to your liking than the behavior of the standard IBM-PC console software. You do not need to be a technical genius to figure out how to set the options for your computer. It just takes some reading, some thought, and a few minutes time. It only needs to be figured out once, unless you change your needs by, for example, changing your display adapter card. You will probably find that it will be worth the effort. Do not worry. You can not hurt your computer by experimenting and trying out different option settings, even if they turn out to be wrong for your display adapter card. The worst thing that could happen is that you would have to start the installation process over again. Sometimes the description for an option refers to other sections of this user manual. If you are unsure about how you want to set that option after reading the description, you may want to read the other sections before deciding. Again, do not worry. You can always change your choice later. The options are set by "parameter switches" which are added to the end of the DOS configuration command in the CONFIG.SYS file. Each option takes the form of an arbitrary number of spaces followed by one slash (or a minus sign, if you prefer) a letter, an equal sign, and a number. If the number starts with a zero, it is considered a hexadecimal number. Otherwise it is considered a decimal number. The letter tells which option is being set and the number specifies the value of the option. It does not matter which case (upper or lower) the letters are. An example is: DEVICE=FCONSOLE.DEV /G=400 /S=10000 DEVICE=FCONSOLE.DEV /G=400 /S=10000 (C) Copyright 1984-85 Hersey Micro Consulting 27 (C) Copyright 1984-85 Hersey Micro Consulting 27 FANSI-CONSOLE Detailed Installation _____________ FANSI-CONSOLE Detailed Installation We use many spaces between options in this manual, only for clarity. You may use as many spaces as you like, or even no spaces. The one exception is that there must be at least one space after the FCONSOLE.DEV file name, if there are any options specified. The options are processed in a left to right order, so if an option is specified more than once, the rightmost instance will be the one which has an effect. The option letters and their meanings are as follows: A - Attributes B - Blink C - Color What You Can F - Font Table Address G - Ctrl-G Bell Length H - Horizontal Retrace Delay I - Initialize with Internal Controller parameters K - Key Bell Frequency L - Lock on Scroll-Lock M - Macro Memory Allocated N - No Color Display O - One Finger Typing P - Page Overlap R - Recall Line Maximum S - Screen Save Timeout T - TTY ROM BIOS Calls Use ANSI X3.64 V - Vertical Retrace Delay W - Word Wide Screen Move X - Extended Features Y - Yuck, You Should Be So Compatible The following subsections describe each option in detail. The chapter entitled "Compatibility and Limitations" indicates appropriate option selections for various hardware configurations, when they differ from the defaults. (C) Copyright 1984-85 Hersey Micro Consulting 28 (C) Copyright 1984-85 Hersey Micro Consulting 28 FANSI-CONSOLE Detailed Installation _____________ FANSI-CONSOLE Detailed Installation A - Attributes _ __________ A - Attributes FANSI-CONSOLE _____________ This option specifies the response that FANSI-CONSOLE should give to the ANSI X3.64 device attributes (DA) command. Setting this option is only important if you have a program expecting to talk to a particular ANSI X3.64 terminal, and it wants the exact response of FANSI-CONSOLE _____________ that particular terminal from the DA command. FANSI-CONSOLE treats this option as a two byte number. The high byte specifies the first value returned, and the low byte specifies the second byte returned. This is easiest to understand when a hexadecimal number is specified, FANSI- ______ by using a leading zero. So for example, /A=00100 makes FANSI- CONSOLE _______ CONSOLE return ESC [ ? 01 ; 00, which is the response code for a DEC VT101 terminal. The default is /A=00000. This may be changed if we get an official implementation number. For more details, see the section entitled "What can the ANSI X3.64 escape sequences do?" in the chapter entitled "ANSI X3.64 escape sequences". B - Blink _ _____ B - Blink FANSI-CONSOLE _____________ This option specifies whether FANSI-CONSOLE should blink the video display on and off when scrolling the color display in the 25x80 alphanumeric screen display mode. It has no effect unless the /H=1 FANSI-CONSOLE _____________ option is used. A value of /B=1 means FANSI-CONSOLE should blink. A FANSI-CONSOLE _____________ value of /B=0 means FANSI-CONSOLE should not blink. Other values are ignored. Blinking the screen during scrolling allows the use of a faster scrolling routine that would otherwise cause "snow" (also known as hashing) on monitors requiring the /H=1 option. If the /H=1 option must be used, we recommend using /B=1 (unless /W=1) because otherwise the scrolling will be too slow. The drawback to blinking is that it is somewhat hard on the eyes. However, this is what the standard IBM-PC BIOS does, so it will appear "normal". The default value is /B=1, because the IBM-PC color graphics card requires the /H=1 option. Related options are /H, /V, and /W. For the IBM-PC color graphics adapter, we recommend /B=1. (C) Copyright 1984-85 Hersey Micro Consulting 29 (C) Copyright 1984-85 Hersey Micro Consulting 29 FANSI-CONSOLE Detailed Installation _____________ FANSI-CONSOLE Detailed Installation C - Color What You Can _ _____ ____ ___ ___ C - Color What You Can FANSI-CONSOLE _____________ This option specifies whether FANSI-CONSOLE should use the ANSI X3.64 SGR current graphics rendition to color the characters written to the FANSI-CONSOLE _____________ screen where possible. A value of /C=1 means FANSI-CONSOLE should FANSI-CONSOLE _____________ use the current SGR. A value of /C=0 means FANSI-CONSOLE should use IBM-PC ROM BIOS compatible coloring. Other values are ignored. This option gives the starting value for the FANSI-COLOR mode, which may later be changed with the ANSI X3.64 FANSI-SM and FANSI-RM commands. If the /C=1 option is used, many programs which would display only white characters on a black background with /C=0, will display characters in the current colors and attributes set by the last ANSI X3.64 SGR command instead. This would normally be the colors and attributes set by the MS(PC)-DOS PROMPT command. To do this, /C=1 forces all screen display mode settings be modified to the equivalent colored variation, if there is one. Also, /C=1 forces the primary graphics rendition to have the last foreground and background colors explicitly set with the ANSI X3.64 SGR command. The default value is /C=0, because this is the IBM-PC compatible setting. We generally suggest /C=1, because it makes many programs use the colors you FANSI- ______ prefer instead of white on black. However, if you insist that FANSI- CONSOLE _______ CONSOLE colors things the same way as the standard IBM-PC software, ____ then you must use /C=0. This option is related to the /N option, which has priority over this option. However, there may be a few programs which do not color things reasonably when /C=1, particularly some games. Note that this option will mostly affect only those programs which normally unintentionally cause the colors to be white on black as a side effect of changing the screen display mode. Programs which intentionally set the foreground and background colors will not be affected. F - Font Table Address _ ____ _____ _______ F - Font Table Address This option specifies the offset in the ROM BIOS segment (F000:) of the normal graphics character set. The default offset is /F=0FA6E (hexadecimal), since this is the address used in the IBM-PC ROM BIOS. If this option is not set appropriately, then the characters ________ ______ _______ _____ displayed in the graphics screen display modes will appear as strange not ___ shapes instead of characters. This is not meant to allow a way to create alternate character sets, but only to specify where the regular graphics character set is in the ROM if you have a non-standard PC. Most people will not need to set this option. This only affects graphics screen display mode characters and not alphanumeric screen display mode characters. Alternate character sets for the graphics screen display modes may be specified in the usual manner. (C) Copyright 1984-85 Hersey Micro Consulting 30 (C) Copyright 1984-85 Hersey Micro Consulting 30 FANSI-CONSOLE Detailed Installation _____________ FANSI-CONSOLE Detailed Installation G - Ctrl-G Bell Length _ ______ ____ ______ G - Ctrl-G Bell Length This option specifies the duration of the Ctrl-G bell. The duration is specified as a delay loop count, so the exact delay time depends upon how fast your IBM-PC or equivalent runs. For the IBM-PC, a count of /G=4096 lasts about one second. The default is /G=4096 because it is the amount of time used by the IBM-PC ROM BIOS. If you like your bell a bit shorter, we suggest the bell given by /G=400. If your computer is faster than an IBM-PC, you may want to increase this number. Specifying /G=0 turns off the Ctrl-G bell entirely. H - Horizontal Retrace Delay _ __________ _______ _____ H - Horizontal Retrace Delay FANSI-CONSOLE _____________ This option specifies whether FANSI-CONSOLE must wait for the horizontal retrace signal on color graphics cards before writing to screen memory in the 25x80 alphanumeric screen display modes. It has FANSI- ______ no effect for monochrome display cards. A value of /H=1 means FANSI- CONSOLE FANSI-CONSOLE _______ _____________ CONSOLE must delay. A value of /H=0 means FANSI-CONSOLE need not delay. Other values are ignored. The default value is /H=1, because the IBM-PC color graphics card requires this delay or else "snow" (also known as hashing) appears when the screen is written to. You may not mind this, but most people do. If your add-on manufacture's color graphics card does not require a delay, then using /H=0 will give a much nicer and faster screen display. The chapter entitled "Compatibility and Limitations" indicates those display adapters for which /H=0 is appropriate. In addition, we have a test program called SNOW. Just run SNOW, and you will able to see which way to set the /H option. Related options are /B, /V, and /W. For the IBM-PC color graphics adapter, we recommend /H=1. For a Tecmar Graphics Master, use /H=0. For Compaq's or Zenith 150's, use /H=0. (C) Copyright 1984-85 Hersey Micro Consulting 31 (C) Copyright 1984-85 Hersey Micro Consulting 31 FANSI-CONSOLE Detailed Installation _____________ FANSI-CONSOLE Detailed Installation I - Initialize with Internal Controller Parameters _ __________ ____ ________ __________ __________ I - Initialize with Internal Controller Parameters FANSI-CONSOLE _____________ This option specifies whether FANSI-CONSOLE should use its own internal parameter values for initializing the CRT controller. A FANSI-CONSOLE _____________ value of /I=0 means FANSI-CONSOLE should use the table given by the FANSI-CONSOLE _____________ ROM BIOS. A value of /I=n means FANSI-CONSOLE should use its FANSI-CONSOLE _____________ internal table number n. Currently, FANSI-CONSOLE has three (3) internal tables. An internal table should be used if you want to give your own starting values which are different from those given by the ROM BIOS. To find the internal tables in a specific version of FANSI-CONSOLE _____________ FANSI-CONSOLE, so that you may change the values, you must specify /I=1 and examine interrupt vector 01D hex. The other tables follow immediately afterwards, in address increments of 40 hex. Generally, we recommend that you do not use /I=1, unless you are an advanced user. So the default value is /I=0. Use /I=2 if you have an IBM Enhanced Graphics Adapter (EGA) and a normal color display. Use /I=3 if you have an EGA and the IBM Enhanced Display or equivalent. If you do not specify the appropriate /I option with an EGA, the display will appear "twisted" or full of "dots", or will "roll" or "blink rapidly". The symptoms vary wildly, but the main point is that the display is totally unreadable. You will also see symptoms like these if the EGA /I options are used with a regular display adapter. In a later release, this will be made unnecessary for the EGA. K - Key Bell Frequency _ ___ ____ _________ K - Key Bell Frequency This option specifies the frequency of the keyboard buffer full bell and of keyclicks. The frequency is specified as a delay loop count, so the exact frequency depends upon how fast your IBM-PC or equivalent runs. The default value is /K=048 because that causes FANSI-CONSOLE _____________ FANSI-CONSOLE's keyboard buffer full bell to sound similar to that of the IBM-PC ROM BIOS. If your computer is faster than an IBM-PC, you may want to increase this number. The keyclick sounds may be made louder by pressing Alt-Ctrl-DarkPlus and quieter by Alt-Ctrl-DarkMinus, just as is normal for Compaq machines. (These are the numeric pad plus and minus keys, respectively). (C) Copyright 1984-85 Hersey Micro Consulting 32 (C) Copyright 1984-85 Hersey Micro Consulting 32 FANSI-CONSOLE Detailed Installation _____________ FANSI-CONSOLE Detailed Installation L - Lock on Scroll Lock _ ____ __ ______ ____ L - Lock on Scroll Lock This option specifies whether to have a one-finger pause key. A FANSI-CONSOLE _____________ value of /L=1 means FANSI-CONSOLE has a one-finger pause key. A FANSI-CONSOLE _____________ value of /L=0 means FANSI-CONSOLE does not have a one-finger pause key. The default value is /L=0, because this is the IBM-PC compatible setting. This option gives the starting value for the FANSI-LOCK mode, which may later be changed with the ANSI X3.64 FANSI-SM and FANSI-RM commands. To use the one-finger pause key when the /L=1 option is used, press the Scroll-Lock key without any shifting keys to cause the display to pause without flushing the typeahead buffer. This key stroke combination works slightly differently than the Ctrl-Num-Lock combination. Unlike Ctrl-Num-Lock, Scroll-Lock acts as a toggle. When the Scroll-Lock pause is on, if the scroll recall feature is also disabled, other keys may be used to type ahead without affecting the pause. If the scroll recall feature is enabled, then scroll recall may be done when the Scroll-Lock is on. Pressing Scroll-Lock a second time clears the pause. You will probably find Scroll-Lock more convenient than Ctrl-Num-Lock, mostly because it is a "one FANSI-CONSOLE _____________ finger" pause key. Any program that works with FANSI-CONSOLE pauses with Scroll-Lock. Pressing the Scroll-Lock key with a shift or Alt key, when the /L=1 option is used, has the same effect as Scroll-Lock does when the /L=0 option is used. In other words, it sets the scroll lock bit for use by the application programs, such as Borland's Sidekick. For other ways to pause, see the descriptions of Ctrl-S and Ctrl-Num-Lock in the chapter entitled "Starting Quickly". If the /L=0 option is specified, this kind of pausing may still be done using the Alt-Scroll-Lock key combination. Of course, it is then a two finger pause! Related options are /P, and /R. M - Macro Memory Allocated _ _____ ______ _________ M - Macro Memory Allocated This option specifies how much read/write memory to reserve for varying space requirements. This memory is used for saving ANSI X3.64 command parameters and keyboard macro strings. To estimate your requirements, add your total keyboard macro string lengths to the length of your longest keyboard macro. The length of a keyboard macro string is the number of characters which get entered when you press the key. Then add 100 and multiply by 1.25. Remember that this is only an estimate. You may be able to do with less space. The value to specify is measured in bytes. The default and minimum value is /M=512. The maximum value is about /M=40000. If the value is out of range, the appropriate limit is used instead. For more details about keyboard macros, see the section entitled "How do I assign FANSI-CONSOLE _____________ strings to FANSI-CONSOLE keys?" in the chapter entitled "Advanced Features". (C) Copyright 1984-85 Hersey Micro Consulting 33 (C) Copyright 1984-85 Hersey Micro Consulting 33 FANSI-CONSOLE Detailed Installation _____________ FANSI-CONSOLE Detailed Installation N - No Color Display _ __ _____ _______ N - No Color Display FANSI-CONSOLE _____________ This option specifies whether FANSI-CONSOLE should attempt to force most programs to use only black and white for the graphics FANSI-CONSOLE _____________ rendition. A value of /N=1 means FANSI-CONSOLE should try to force FANSI-CONSOLE _____________ only black and white to be used. A value of /N=0 means FANSI-CONSOLE should allow the use of color. Other values are ignored. If the /N=1 option is used, many programs which would use color with /N=0, will display characters in black and white instead. To do this, /N=1 forces all screen display mode settings be modified to the equivalent monochromatic variation, if there is one. Also, /N=1 forces the primary graphics rendition to have the last foreground and background colors explicitly set with the ANSI X3.64 SGR command. The default value is /N=0, because this is the IBM-PC compatible setting. We generally suggest /N=0, unless you have a monochrome display connected to a color display adapter and you find that some colored characters are not readable on your display. This option is related to the /C option, which this option has priority over. This option gives the starting value for the FANSI-NOCOLOR mode, which may later be changed with the ANSI X3.64 FANSI-SM and FANSI-RM commands. Programs which intentionally set the foreground and background colors will not be affected. O - One Finger Typing _ ___ ______ ______ O - One Finger Typing The option is the letter O This option specifies whether to allow one finger typing. A value of FANSI-CONSOLE _____________ /O=1 means FANSI-CONSOLE will toggle the Alt, Ctrl, or shift key states only when you press the appropriate key, and not when you release it. This means that you remain Alt'ed, Ctrl'ed, or shifted until you press the key again. Note that in this situation, each shift key is a separate shift lock and both must be off to get FANSI-CONSOLE _____________ unshifted characters. A value of /O=0 means FANSI-CONSOLE will toggle the Alt, Ctrl, or shift key state both when you press the appropriate key, and when you release it. The default value is /O=0, since this gives the normal behavior of keyboards. The /O option is for handicappers and others who find it impractical to press multiple keys at once, such as both the control key and an not alphabetic key. If you are not physically handicapped, you probably will want to use /O=0. This option has nothing to do with whether you are a touch typist versus whether you hunt and peck. (C) Copyright 1984-85 Hersey Micro Consulting 34 (C) Copyright 1984-85 Hersey Micro Consulting 34 FANSI-CONSOLE Detailed Installation _____________ FANSI-CONSOLE Detailed Installation P - Page Overlap _ ____ _______ P - Page Overlap This option specifies the starting value of the number of lines of overlap between pages used by the scroll recall feature. A value of /P=0 also implies that no status line should be shown on the recall screen, so that the whole screen may be seen. A value of /P which is more than zero also implies that a status line should be shown at the top of the recall screen. The default value is /P=4. For more details about the scroll recall feature, see the section entitled "How do I recall lines which have scrolled away?" in the chapter entitled "Advanced Features". Related options are /L, and /R. R - Recall Line Maximum _ ______ ____ _______ R - Recall Line Maximum This option specifies how many lines of space to reserve for the scroll recall feature buffer. A value of /R=0 means that no space is reserved for the scroll recall feature, which means that scroll recall is completely unavailable. A non-zero value for /R implies that the scroll recall feature is initially on. A non-zero value for /R which is less than 50 implies that 50 lines are reserved for scroll recall, since there must be enough room in the buffer for at least one screenful, and screens may be as much as 50 lines high. A value for /R which is at least 50 lines indicates that exactly that many lines of memory are reserved for scroll recall. Each line requires 160 bytes of memory. For example, /R=100 requires about 16 KB more read/write memory than /R=0. The default value is /R=0, since this gives the minimum space usage. For more details about the scroll recall feature, see the section entitled "How do I recall lines which have scrolled away?" in the chapter entitled "Advanced Features". Related options are /L, and /P. (C) Copyright 1984-85 Hersey Micro Consulting 35 (C) Copyright 1984-85 Hersey Micro Consulting 35 FANSI-CONSOLE Detailed Installation _____________ FANSI-CONSOLE Detailed Installation S - Screen Save Timeout _ ______ ____ _______ S - Screen Save Timeout FANSI-CONSOLE _____________ This option specifies whether FANSI-CONSOLE should use its screen saver feature and how long the timeout should be. The value used is the number of 1/18.2 second intervals counted before turning off all the display output. If no keys are pressed or there is no output from a program using ROM BIOS calls or MS-DOS before the timeout, the console screen display is automatically turned off. This is to prevent you from accidentally permanently burning a pattern into your display screen by displaying the same thing on the screen too long. When the display is turned off, any key including a shifting key may be pressed to turn the display back on. When the display is turned back on, the data displayed appears the same as it did just before the display was turned off. The default count of /S=0 may be used to specify always keeping the screen display on, which is the behavior of the standard ROM BIOS software. We do not recommend this setting, but we make the defaults as compatible as possible with the standard, to avoid surprising people. Otherwise the timeout can be as much as about one hour if /S=0FFFF is used. We suggest /S=10000, for a timeout of about ten minutes. 18.2 units/sec * 60 secs/min * 10 min = 10920 units, actually. Note that some programs set the border, color palette, or screen display mode directly instead of through the BIOS calls. Such programs include some painting programs, like PC Paint, and some programs which use more than one screen display mode to option between graphics and text, like Lotus 123. When these programs are used and the screen is disabled and then restored, the border or palette may be a different color than before the screen was disabled, or the screen may appear totally distorted. This is because hardware state of these values cannot be read and then restored, but they must FANSI- ______ be changed to disable the screen. So to do the restore, FANSI- CONSOLE FANSI- _______ ______ CONSOLE must assume the values were as they were last set by FANSI- CONSOLE _______ CONSOLE. (C) Copyright 1984-85 Hersey Micro Consulting 36 (C) Copyright 1984-85 Hersey Micro Consulting 36 FANSI-CONSOLE Detailed Installation _____________ FANSI-CONSOLE Detailed Installation If you specify the /S option but the screen does not turn off after the specified period, then it may be that your display adapter card has no way to disable the video signal. There is no way to have the /S option work with such adapters. It may also be that the way the video signal enable is turned off is different from that required by FANSI-CONSOLE _____________ IBM standard cards. FANSI-CONSOLE may have an extended features option which must be used with such an adapter. See the description of the /X options below. If you specify the /S option and it works, but only sometimes, then you are probably running a program which replaces the timer interrupt vector instead of chaining to it. If a FANSI-CONSOLE _____________ program does this, then FANSI-CONSOLE is only able to turn off your _____ display while that program is not running. If the same program also FANSI-CONSOLE _____________ does not restore the timer interrupt vector, then FANSI-CONSOLE is _____ also not able to turn off your display after that program is done. If a program does this, it is a problem with that program, and not FANSI-CONSOLE _____________ with FANSI-CONSOLE, but please tell us about the program. T - TTY ROM BIOS Calls Use ANSI X3.64 _ ___ ___ ____ _____ ___ ____ _____ T - TTY ROM BIOS Calls Use ANSI X3.64 This option specifies whether the ROM BIOS video call for TTY output (INT 10 hex with AH = 15 decimal) should process ANSI X3.64 standard FANSI-CONSOLE _____________ escape sequences. A value of /T=1 means FANSI-CONSOLE will process the ANSI X3.64 standard escape sequences found in the TTY output FANSI-CONSOLE _____________ calls. A value of /T=0 means FANSI-CONSOLE will process the TTY output calls in a way compatible with the IBM-PC ROM BIOS. The default value is /T=0. We generally recommend /T=0, for compatibility. With /T=1, some communications programs may be made to process ANSI X3.64 escape sequences properly, and emulate an ANSI X3.64 standard terminal, even when those programs do not normally have that as a feature.
