This text file has been translated to english by someone other
than the author, and as such, may or may not contain errors (I'd like
to think that it is completely correct, but I've never actually
studied german, and have relied on RufTrade (a new and wonderful
shareware german to english translator program (yes, I've sent my
money in!), and my dictionary)). I have tested the instructions, and
most of the rest (I couldn't make any of the errors occur), and it
seems to be okay, but I make no warranty that the information in this
text file will work, or that it won't do anything nasty. The author
has absolutely nothing to do with this translation, so he cannot be
held responsible either. This english text file is not part of the
Duet package, unless the author himself includes it, and if he does,
all the more power to him. Pay the shareware fee for this if you use
it. It seems like a wonderful program, and I'm not keen on
programmers for my machine of choice taking off for greener pastures.
This programmer has a very open mind it seems where the shareware fees
come in, so at least send him something! <stepping off the soap box>
Anyway, it seems to be more or less right, so I hope it helps you
install this program, and possibly understand it a little better.

Duet is Shareware, d. h. it may not be copied, used or passed
along for commercial purposes, but may be distributed freely and only
in unchanged form. The free distribution over mail-boxes is allowed
and desired.
If you use Duet regularly, you are asked to send me the amount of
money that you feel the program is worth. There is no minimum or
maximum; that is up to you to decide. If you have no money, perhaps
you could send me a few nice words on a beautiful postcard.
If enough people use shareware regularly, do not pay for it,
(surprise!) and it becomes apparent that there is no market for
shareware in the Atari world, the platform will die.
It is necessary for everyone to show interest in good shareware
programs by registering. If you are one of the unpaid shareware
users, keep in mind that if you don't support the platform of
shareware, the platform will dry up and leave you with a severely
crippled system. It's up to you!
Shareware offers the opportunity to test a program before you
decide to buy it. The shareware price pays for the most current
version, which may be the one that is already possessed and/or used.
If you are not content with the currently available version of the
program, it is not a bad idea to make the author aware of errors and
suggestions, and if still interested in the program, wait upon the
answer of the author. However, even if one is not completely
satisfied with the program, if you use the program regularly, the
shareware fee still applies.
If the program doesn't please you, you don't need to use it.
Responsibility
-
You use Duet at your own risk. I undertake no responsibility for
any damage, whether through legitimate or unintentional use of Duet.
Duet works for me with no trouble at all. If this is valid for any
other computer configuration, I have no idea (having only a limited
computer zoo, I can only test certain configurations). Anyone who
wants to use Duet should, at least for the time being, read through
the entire text.
Meaning and purpose of Duet
-
Duet allows the connection of two TOS-based computers (ST/STE/TT/
Falcon etc..) over the MIDI, LAN or serial interfaces, the purpose of
which is to allow each computer to use the other's drives (floppy and
hard disk) and printer.
Running Duet
-
Duet terminates after it installs itself, just like Big Net. It has
internal (copying of the principal function at BIOS-plane) but
nothing more to do with this or other Little Net derivative.
Duet works at the BIOS level. It is on the one hand dependent on
it, that constant BIOS-calls result (below 'normal' TOS-versions,
that is). On the other hand, the drives of the other computer are
available via the BIOS plane as well. This offers some advantages,
but also at least one major disadvantage, that those of you might
have guessed - if both machines are writing to the same partition at
the same time, (this is not a problem if both system are left in the
'Read-Only' state) there is a very good possibility that the
partition will have its FAT destroyed, effectively erasing all of the
files! The 'Read/Write' state should only really be used if there is
absolutely no way that both computers will be accessing the same
partition simulataneously.
Installation
-
First, you have to decide what interface you want to make the
connection on. In the case of a 'normal' ST, MIDI is the fastest
interface (this offers 31250 baud). If you have a computer with
faster interfaces such as a TT connecting with an ST (its serial
interface in the original state maximum 19200 Baud), you might
consider, with a little work, a faster serial interface could be
installed, and this interface could be used. To this purpose, I
recommend Harun Scheutzow's RSVE or Stephan Skrodzki's RS_Speed. With
it (and the suitable drivers) you can obtain with an 8 MHz ST with a
TT over the serial interface a (Bit-)transmission speed of 57,600
baud. If you have two computers with a LAN-interface, you can
alternately use this for the connection. Unfortunately, the program
for using the Falcon's LAN interface does not function correctly;
without doing tests on a Falcon, it seems unlikely to work.
Harun Scheutzow's ST_ESCC is not, at present, supported, due to the
fact that I do not have information on the heightened abilities of
the 85C230.
Once you have decided on the interface you'll be using, the
interface must be the same on both computers. With the MIDI
interface, the MIDI OUT on one computer must be plugged into the MIDI
IN, and the opposite is also necessary to make the network ring.
With a serial connection, in each case TxD must be connected to RxD
of the other computer using a null modem. Handshaking is not
necessary.
You must use the correct driver for the chosen interface.
With a 'normal' ST one can, admittedly, using corresponding hardware
(see above) reach a transmission speed of 57,600 Baud. However, the
'normal' ST cannot actually receive the characters at that speed,
even if RSVE or RS_Speed can (at maximum capacity the computer would
have to be able to use data at 5,760 bytes per second). A 'normal' ST
can use data at a maximum of about 4000 bytes per second. So, to use
a faster computer with a slower computer at the connection speed of
57,600 baud, the faster computer must insert a break between two
characters. To serve this purpose, the faster computer must use one
of the special drivers, the programs that contain a 'D' (as in
"delay") on the end of the name (e.g. DUET_S2D.PRG). These drivers
activate the normally unused Timer A of the MFP.
Program name | driver for

DUETLANF.PRG | LAN-interface of the Falcon (*)
DUETLANT.PRG | LAN-interface of the TT/Mega STE
DUETMIDI.PRG | MIDI-interface
DUET_M.PRG | 'normal' serial interface (MODEM 1 of the TT/Mega STE)
DUET_M2.PRG | MODEM 2 of the TT/Mega STE
DUET_M2D.PRG | MODEM 2 of the TT/Mega STE with break insertion
DUET_MF.PRG | serial interface of the Falcon
DUET_MFD.PRG | serial interface of the Falcon with break insertion
DUET_S2.PRG | SERIAL 2 of the TT/Mega STE
DUET_S2D.PRG | SERIAL 2 of the TT/Mega STE with break insertion
(*) this driver did not function when tested, but may do so in the
future hopefully.
Once you have selected the appropriate driver, you must insert it
into your AUTO folder. DUETCONF.PRG and DUETCONF.INF must also be
added to the AUTO folder.
DUETCONF.PRG must come after the driver in t
