Several folks have pointed out that they never saw the orginal posting
of Mtools v1.6. Is it possible that it didn't actually go out??? I
have been having some trouble with my unix-pc.* news feed, so I guess
anything is possible... So, here is a repost (I think) of the most
current version (with the two patches already installed).
Sorry for any confusion...

This is part 1 (of 2) to the Mtools v1.6 distribution package. Mtools
is a collection of MSDOS tools to allow you to read and write to MSDOS
formatted diskettes from a Unix based system.
The following MSDOS commands are emulated:
Mtool MSDOS
name equivalent Description
----- ---- -----------
mcopy COPY copy MSDOS files to/from Unix
mdel DEL/ERASE delete a MSDOS file
mdir DIR display a MSDOS directory
mmd MD/MKDIR make a MSDOS sub directory
mrd RD/RMDIR remove a MSDOS sub directory
mread COPY low level read (copy) a MSDOS file to Unix
mren REN/RENAME rename an existing MSDOS file
mtype TYPE display contents of a MSDOS file
mwrite COPY low level write (copy) a Unix file to MSDOS
Please remember... Providing a custom device driver to suit your floppy
drive is beyond the scope of this program.
As always, there is a shell archive called Unixpc.shar that contains
the files specific to the AT&T Unix PC 7300/3b1.
Have fun...

XHow to configure Mtools for non-standard disk formats...
X
XThere are three approaches to the problem of trying to read and write
XMSDOS formatted diskettes in a Unix box doesn't have a floppy drive
Xthat meets the physical drive requirements. For example, if your
XUnix box only has a 80 track floppy, you can:
X
X 1) Get a device driver to "double step" the 80 track drive
X to read and write to 40 track diskettes.
X
X Pros: No new hardware costs.
X Cons: Device drivers are a bitch to write (or
X expensive to buy).
X Success rates are low when using 80 track
X drives to write 40 tracks.
X
X 2) Get a conventional device driver and purchase a 40 track
X drive. You'll still need the device driver unless your
X Unix vendor was thoughtful enough to leave you some "extras".
X
X Pros: High success rates (40 track to 40 track)
X Cons: The "foriegn" drive may cause trouble with
X maintenance contracts
X
X 3) Purchase a 80 track drive for your PC. This exploits the
X fact that MSDOS already has a configurable device driver
X feature.
X
X Pros: You don't alter your Unix box in any way.
X Cons: You'll have to process all MSDOS diskettes
X thru the one PC before using Mtools.

XHow to customize Mtools...
X
XThe program can be easily customized to accept non-standard disk
Xformats. For example, a popular disk format for Unix machines seems to
Xbe 80 track, double sided, 8 sector. This doesn't conform to any of the
XIBM standard formats, but MSDOS 3.2 (or greater) can be made to format
Xvirtually anything using DRIVPARM (or DRIVER.SYS) in the CONFIG.SYS
Xfile. Let's take a hypothetical case of a brand X Unix machine with a
X80 track, double sided, 8 sector disk drive. You could purchase an
Xexternal 80 track drive for your IBM compatible computer and format the
Xnew drive D: under MSDOS with the following in your CONFIG.SYS file
X
X DRIVPARM=/D:2 /T:80 /S:8 /H:2 /F:2
X or
X DEVICE=DRIVER.SYS /D:2 /T:80 /S:8 /H:2 /F:2
X
XThen, you would edit the init.c file to include the new non-standard
Xparameters. You might need Norton Utilities, or some other program, to
Xdetermine the statistics of the format. Using our example, the format
Xwould have the following parameters:
X
X FAT#1 sectors 1 - 3 fat_len = 3
X FAT#2 sectors 4 - 6 dir_start = 7
X DIR sectors 7 - 13 dir_len = 7
X cluster size is 2 sectors clus_size = 2
X there are 633 clusters num_clus = 633

XVerbose mode. Display the new file name if the Unix file name requires
Xconversion.
X.TP
X.B m
XPreserve the file modification times.
X.PP
XIf the target file already exists, and the

Xoption is not in effect,
X.I mwrite
Xasks whether or not to overwrite the file.
X.PP
XReasonable care is taken to create a valid MSDOS filename. If an
Xinvalid name is specified,
X.I mwrite
Xwill change the name (and display the new name if the verbose mode is

XThe environmental variable MCWD may be used to establish a current

X MTOOLS
X version 1.6.2 - 5 Jul 89
X
XThis is a collection of MSDOS tools to allow you to read and write to
XMSDOS formatted diskettes from a Unix based system.
X
XThe following MSDOS commands are emulated:
X
XMtool MSDOS
Xname equivalent Description
X----- ---- -----------
Xmcopy COPY copy MSDOS files to/from Unix
Xmdel DEL/ERASE delete a MSDOS file
Xmdir DIR display a MSDOS directory
Xmmd MD/MKDIR make a MSDOS sub directory
Xmrd RD/RMDIR remove a MSDOS sub directory
Xmread COPY low level read (copy) a MSDOS file to Unix
Xmren REN/RENAME rename an existing MSDOS file
Xmtype TYPE display contents of a MSDOS file
Xmwrite COPY low level write (copy) a Unix file to MSDOS
X* CD change working directory
X
X * by use of the environmental variable MCWD
X
XThe formats of IBM PC floppy disk drives are:
X
X bytes per sectors per tracks number total disk introduced
X sector track per side of sides capacity size in MSDOS
X 512 8 40 1 160k 5.25 1.0
X 512 9 40 1 180k 5.25 1.1
X 512 8 40 2 320k 5.25 2.0
X 512 9 40 2 360k 5.25 2.0
X 512 15 80 2 1.2M 5.25 3.0
X 512 8 80 2 720k 3.5 3.1
X 512 16 80 2 1.4k 3.5 3.2
X
X
XThe following may be typical Unix device names for the IBM formats:
X
X /dev/rflp 'generic' used first to test the media
X /dev/rflp40t8s1s 40 track 8 sector single sided
X /dev/rflp40t8s2s 40 track 8 sector double sided
X /dev/rflp40t9s1s 40 track 9 sector single sided
X /dev/rflp40t9s2s 40 track 9 sector double sided
X /dev/rflp80t15s2s 80 track 15 sector double sided
X
XThese device names are in the msdos.h file as #defines and must be
Xedited to match the device names on your system. If your device driver
Xdoes not handle all of the formats shown, then you should leave those
Xparticular devices undefined in the msdos.h file.
X
XThe manuals are very terse... it's assumed that the reader is already
Xfamiliar with MSDOS.
X
XThe use of the environmental variable MCWD to keep track of the current
Xworking directory is a little awkward, especially since there is no
X'change directory' command. Bourne shell users will have to type two
Xcommands to initially set their working directory, ie:
X
X MCWD=/TMP
X export MCWD
X
XWildcards are only applied to filenames and not to directory names. For
Xexample '/usr/local/*.c' is appropriate, but '/usr/l*/main.c' is not.
X
XI really wanted to avoid the use of a 'text' mode and a 'data' mode when
Xtransferring files, but I couldn't find a better way. It gets rather
Xconfusing and it's quite possible to mess up a file if you apply the
Xtext mode when it is not appropriate (ie: to a COM or EXE file).
XLikewise, if you forget to apply the text mode (to a Unix text file)
Xthen if the file is used under MSDOS, it will be missing carriage
Xreturns. However, if you aren't going to use the files on your Unix
Xsystem (you just intend to hold the files and then transfer them back to
XMSDOS later) then you shouldn't use the text mode during either mread or
Xmwrite. This is because, the text mode is only useful if the files are
Xgonna be used under Unix.
X
XThe implementation of the Mcopy command is somewhat clumbsy since the
XMSDOS drive designation "A:" is used. Mcopy is really a front-end to
Xthe low level Mread and Mwrite commands.
X
XThere are is a shell archives called "Unixpc.shar" that contain files
Xspecific to the AT&T Unix PC 7300/3b1.
