TeleDisk At a Glance What TeleDisk Is TeleDisk is a utility which will convert any diskette into a file and vice- versa. The diskette need not be a DOS diskette; certain types of "copy- protected" diskettes are also handled. The result is an exact copy of the original diskette. The file produced by TeleDisk is compressed to minimal size and is handled by most telecommunications file transfer protocols, in- cluding Kermit and XMODEM. We initially had a problem in explaining in ten words or less exactly what it was that TeleDisk did. One of our customers hit on the description of TeleDisk as a "diskette FAX machine". A very accurate description! We at Sydex develop software and we also carry out support activities for that software. Part of any "bug hunting" operation is the task of duplicat- ing problems. And part of duplicating problems is obtaining the necessary supporting materials. If "supporting materials" means only one or two files, obtaining them is easy - just upload them via a modem and a communications package. If, however, the supporting material takes the form of many files in several directories, or worse yet, data on a diskette from an alien system in an unknown format, getting the information over a telephone line can be a big problem. Our only viable response in such a case had been "Can you Fed Ex it to us?". Clearly, something better was warranted. And so TeleDisk was born. This utility allows you to take a diskette and convert it into a file. You can then transmit this file using your favorite communications program and again use TeleDisk to reconstruct an exact copy of the diskette from that file. No muss, no fuss - and very easy to use. Some applications immediately suggest themselves: * "No brainer" file transmission. Just send the whole diskette without worrying about getting all the right files. * Preservation of disk directory entries, including hidden, read- only and system files, as well as volume labels and directories. * Transmit diskettes complete with boot sectors. * Transfer "foreign" diskette formats - an answer to how to send a diskette from, say, a Wang word processor over the phone lines. * If diskette image files are placed on a hard disk, they can be saved on a streamer tape backup unit. * Transfer entire diskettes over a network. Page 1 TeleDisk at a Glance ___________________________________________________________________________ About "copy protected" diskettes... It is not the intent of Sydex to en- courage copyright violation by making it easier to transmit "copy protected" diskettes. It may be true that TeleDisk will handle a number of copy protection schemes, resulting in a faithful reproduction of the original; however, this is a necessary "side effect" of the basic operation of TeleDisk. Please note that most commercial software agreements do not authorize you to redistribute copyrighted material to third parties, and that by doing so, you may be held in violation of U.S. copyright law, as well as being held liable for civil damages. TeleDisk has a number of interesting features: * The ability to copy one or both sides of a diskette. * The ability to copy just the diskette sectors allocated by DOS. * Optional use of an "advanced" data compression algorithm (LZSS- Huffman) to produce minimal file size. * Automatic "splitting" of files across several diskettes if neces- sary. This is essential for diskette-only systems. * Menu-driven with online help screens. * Support of low-density (180K and 360K) formats as well as high- density (1.2M and 1.44M) formats. Single-density diskettes may also be processed, if the hardware permits. How To Use It TeleDisk will run under any version of MS-DOS or PC-DOS from 2.1 on. It will also operate in the DOS Window under OS/2. We haven't tested it with Digital Research's DR-DOS, but we have no reason to believe that it won't work with it. Anything from an original PC to a 80486 system should be adequate. A cer- tain amount of PC compatibility is required; TeleDisk will not work with the IBM PC Jr., the Tandy 2000, or the very low-end Tandy 1000 systems, such as the 1000 EX or 1000 HX. If you have a typical PC XT-compatible system with up to four 360K diskette drives or an AT-compatible with up to two diskette drives, TeleDisk should operate "right out of the box". If you have an XT-compatible with 3.5" or a 5.25" high-density drive, or an extra diskette adapter, you'll need to specify your configuration by running the TDCONFIG program. If you have an AT-compatible with more than two diskette drives, you'll also need to use the TDCONFIG program. If you're using a PS/2 with more than one diskette drive, you'll need to run TDCONFIG. A description of TDCONFIG is presented in the next section. Otherwise, just execute the command: TELEDISK Page 2 Configuring TeleDisk ___________________________________________________________________________ No other files are needed. TeleDisk normally generates its displays in color, hardware permitting. If, however, a monochrome display is required, it may be had by executing: TELEDISK /M After this point, it's only necessary to follow the directions on the menus; press the F1 key for online help. The ESCape key is used to ter- minate the current activity. If you are using a diskette-only system, you should have one or two blank, formatted diskettes to hold output file which TeleDisk produces. It's good practice to write-protect the source (ori- ginal) diskette when you are making a file from it using TeleDisk. All TeleDisk files have an filename extension (type) of TD0 through TD9. Configuring TeleDisk--TDCONFIG As was mentioned in the preceding section, TeleDisk normally needs no cus- tomization. However, users with any of the following equipment configura- tions should pre-configure TeleDisk: 1. A PC XT or compatible with 3.5" drives or 5.25" high-density drives. 2. Any system with more than one diskette adapter card. 3. Any system with external diskette drives. 4. Any system using the MicroSolutions CompatiCard. 5. Toshiba T3100 owners. 6. Any system with a line of the following form in the CONFIG.SYS file: DEVICE=DRIVER.SYS... To pre-configure TeleDisk, start the configuration program by entering the following DOS command: TDCONFIG TDCONFIG prompts for the location of the TELEDISK.EXE file and where the configured TeleDisk is to be placed. A few questions are asked about the computer system hardware; almost all are answered with a simple "Yes" or "No". If TeleDisk is being configured for a PC XT or compatible with high-density diskette drives, the system must be identified as a PC AT instead of a PC XT. Toshiba T3100 owners without the 1.44Mb high-density option should identify their system as a PC XT, rather than as a PC AT. A disk drive display will be presented, similar to that shown in Figure 1. Page 3 Configuring TeleDisk ___________________________________________________________________________ TDCONFIG prompts for drive characteristics with short multiple-choice ques- tions for each field. Note that there must be no free entries (marked with "(NONE DEFINED)") between drive entries; that is, all of the free entries must come at the end of the table. The drive letter field can be any letter of the alphabet. In addition, a given physical drive may be reproduced several times in the drive table un- der different drive letters. ┌─────────────────────────────────────────────────────────────────────────┐ │ DISKETTE CONFIGURATION │ │ │ │ The following diskettes are present on your computer: │ │ │ │ │ │ NO.

If only one dis- kette adapter is present, units 0 through 3 generally correspond to drives A: through D:, with E: being the first hard disk. No diskette adapter ad- dresses more than four units; each additional adapter begins the unit ad- dress sequence all over again with unit 0. The adapter field is set to PRIMARY if only one diskette adapter is present on the system. A second diskette adapter is designated as SECONDARY; its I/O port base address most commonly is 370. However, some secondary dis- kette adapters, most notably the CompatiCard, can deviate from this; con- sult the manufacturer's reference material for information. The drive type field simply reflects the maximum capacity of the correspond- ing diskette drive. Thus, a 1.2Mb high-density drive need only appear once for both 1.2Mb and 360K operating modes. Page 4 Getting Started ___________________________________________________________________________ All modern diskette drives can operate at a 6 millisecond stepping rate. If a drive appears to be excessively noisy, this time should be shortened to 4 milliseconds. Very old 8" drives can be accommodated with stepping rates up to 28 milliseconds. The resulting pre-configured TELEDISK.EXE file can be saved on any disk or directory. Getting Started With TeleDisk The whole of TeleDisk is contained in the file TELEDISK.EXE; no other files are required. To start TeleDisk, simply enter TELEDISK at the DOS command prompt. If your computer has a color display adapter, TeleDisk will make use of color in its displays. If you have a monochrome display connected to a CGA or EGA, you'll probably want to suppress color selection by invoking TeleDisk with TELEDISK /M TeleDisk normally searches the current (default) directory for data files. A different directory or drive may be specified with the TELEDISK command: TELEDISK C:\MYDIR After a brief sign-on display, the menu shown in Figure 2 is displayed.

In addition, the ES- Cape key usually terminates the current operation and return to the previ- ous display. Error conditions are signaled by an "Alert" which pops up over the current display. Figure 3 shows the result of a duplicate file situation. The "Alert" box may be moved around the screen through the use of the cursor keys. If the F1 key is pressed, a help screen giving more information about the error condition is displayed. Selection of the function to be performed by TeleDisk is also accomplished with the cursor keys. To make a file from a diskette, use the cursor keys to position the blink- ing area to Copy Disk to File and press the ENTER key. To recreate a dis- kette from a file, use the cursor keys to position the blinking area to Copy File to Disk and press the ENTER key. The choice Copy Disk to Disk is the equivalent of a Copy Disk to File fol- lowed by a Copy File to Disk using the same file; no file is actually created, however.

Check Diskette for Data has meaning only if the diskette is not a DOS dis- kette and DOS Allocated under Read Which Sectors has been selected. If Both Sides is selected, both sides of the diskette are inspected for data. If only one side is found to contain data, then only that side is examined. If One Side is selected, the second surface of the diskette will not be ex- amined. This feature is useful when a single-sided diskette has been copied to a diskette which has had both sides formatted.

If Both Sides is selected, no interpretation of the diskette is attempted, and all sectors on the diskette are recorded verbatim. If DOS Only is selected, an attempt will be made to recognize the diskette as having one of the standard DOS formats. If the diskette does, in fact, contain a recognizable DOS file structure, then only those sectors actually belonging to data files will be recorded. The DOS Only mode of copying is generally at least twice as fast as the non-DOS mode because certain assumptions can be made concerning the diskette format. Side 0 and Side 1 cause the data from just that side to be copied to the image file. Page 7 Creating Diskette Image Files ___________________________________________________________________________ Data Compression Method determines how much effort should be spent "squeezing" the diskette file to its smallest representation. Normal causes simple repeated-byte compression to be used and operates quite rapidly. Advanced compression make use of Lempel-Zev and adaptive Huffman techniques in addition to repeated-byte compression. Advanced compression is somewhat slower than normal compression, particularly on XT-class com- puters, but typically results in an output file size 40-50 percent smaller than that achieved with normal compression only. After the appropriate selections have been made, the ENTER key is pressed and a prompt appears for the name of the file to which the diskette informa- tion will be written. If the file name supplied contains an extension, that extension will be ignored. All TeleDisk files are initially created with an extension of TD0. If an output file is created on a diskette and the diskette has insuffi- cient room to hold the entire initial TD0 file, TeleDisk prompts for another diskette and creates a new file with a TD1 name extension. This process continues from diskette to diskette until the Copy Disk to File operation is complete. If such a multi-volume file is used when a File to Disk operation is per- formed, TeleDisk will prompt for each diskette as it is required. If all volumes were copied to a hard disk, all files are accessed without prompt- ing.

Full editing functions using cursor keys, including insert and overtype modes are available. In addition, line-drawing semigraphic characters are available as Alt-shifted keys on the top row of the keyboard. More specific information is avail- able through the F1 "help" key facility.

However, Version 2 files usually will not be read successfully by the Ver- sion 1 product. Because of its pre-configuration capability, Version 2 TeleDisk can make better informed decisions regarding the compatibility of diskette formats. The Advanced Compression algorithm of Version 2 is entirely new; in general, it more consistently results in significant file space savings. Files with comment records cannot be read by TeleDisk versions earlier than 2.10. However, "comment-less" files may still be produced by later ver- sions of TeleDisk.
