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.

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.

Figure 1: TDCONFIG Diskette Display
The unit field is perhaps the cause of the most confusion. 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.

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.

The F1 key always brings up a help display, whose content is dependent on
the function being performed (context-sensitivity). 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.

Creating a Diskette Image File
When the Copy Disk to File operation is selected, the menu shown in Figure
4 appears.
Source Diskette Drive is the drive containing the diskette to be copied.
This drive may also be used for the resulting output file - a prompt will
be issued when diskettes need to be switched.
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.

Read Which Sectors determines how the source diskette data is interpreted.
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.

After the file name has been entered and TeleDisk has succeeded in creating
the file, the operating display appears and TeleDisk proceeds with the copy
operation.
When enough data has been copied from the source diskette to fill
TeleDisk's internal buffer, the window shown in Figure 5 appears. A com-
ment up to 8 lines of 72 characters may be entered. 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.
If no comment text is entered, the comment record will be omitted from the
image file produced. This "comment-less" image file is compatible with ear-
lier versions of TeleDisk.

Figure 9: Disk to Disk Menu
The Operating Display
After the operating function and its parameters have been selected, the dis-
play shown in Figure 10 appears.
Notice the "thermometer" at about the middle of the display. TeleDisk uses
a "bar" indicator as the operation proceeds to give an indication of the
progress of the operation. The numbers on the "thermometer" correspond to
diskette track numbers. A 360K diskette contains 40 tracks; 720K, 1.2M and
1.44M all contain 80 tracks. Thus, if the thermometer bar indicates 20 on
a 1.2M diskette, the operation is about one-quarter complete.
Prompts for diskette changes, as well as error conditions appear in "Alert"
boxes as described earlier.

Figure 10: Operating Display
The GENERAL portion of the screen tells what was discovered during the
course of analyzing the diskette, or from reading the file from which a dis-
kette is to be produced. A note is made of the following:
* Single- or Double-sided diskette
* Diskette density
* Data compression method used
* Sector address range on each side

The ANALYSIS display presents a running narration of operation. The dis-
play scrolls as it becomes filled and provides a track and side "tag" for
each item of information displayed.

Compatibility/Revisions
___________________________________________________________________________
When the selected copy operation is complete, an "Alert" box message ap-
pears. Pressing any key at this point will cause TeleDisk to return to the
opening menu.
Compatibility With Older Versions
Files produced by Version 1 TeleDisk can be read by the Version 2 product.
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.
