- Medium Net Description
- =======================
-
- Now, the suction. Medium Net was built upon the transmission routines
- from Dirk Woitha's 'Little Net'. Little Net is already fast
- and in all common aspects it functions the same, only it can now:
-
- 1. Access several if not all Disk drives simultaneously over the Net.
-
- 2. The configuration can be saved
-
- 3. The length ... or?
-
- 4. Also, BGM-Partitions should also now work, this is however
- still a litle flakey...
-
-
- I am still working on making the whole thing run over the 2.Serial
- (115 kBaud,grins)
-
- Also the description of 'Little Net' is fairly accurate so I will now
- continue with it and make only a few remarks in it.
-
-
- LITTLE NET Description (more or less)
- =======================
-
-
- How do I connect the computers?
- -------------------------------
-
- With the MED_NET.ACC you can network two ATARI STs over MIDI lines.
-
- To accomplish this you must either join the MIDI In and MIDI OUT between
- the two computers over two ready made Stereo cables, or make themself
- a suitable cable. To accomplish this respectively Pin 4 and 5 from MIDI
- OUT with Pin 4 and 5 (also 4 an 4 and 5 an5) from MIDI In on the other
- Computer must be joined.
-
- Anyone who only has one ST but wants to see 'Little NET' for themselves
- can connect the MIDI OUT on their computers directly to their MIDI IN.
- ;)
-
- Also: Two Cable, one from MIDI In(1) to MIDI OUT(2) and one from
- MIDI In(2) to MIDI OUT(1).
-
- (Work around every flaw!)
-
-
- How do I work with Medium NET?
- -------------------------------
-
- First you must copy the MED_NET.ACC and MED_NET.RSC to your
- boot partition. Once you have installed it on both computers,
- you will need to reboot.
-
- When you call up the accessory and activate the virtual Drives (most of
- them :-)), you end up without a gap in the physical partition list.
-
- Synopsis:
-
- Using computer(1), select which disk drives on computer 2 you'd like to
- have access to inside the Medium NET ACC. Then, using computer(2), select
- which disk drives on computer(1) you'd like to have access to on computer
- one with the Medium NET ACC.
-
- example:
-
- computer(1) has the 'genuine' Disk-drives A,B,C,D and computer(2) only
- has Drive A.
-
- computer(1) turns on Drive A in his Medium NET .ACC (the other has it also
- otherwise nothing will happen), then Drive A appears on computer(1) as
- Disk-drive E (E is the next open drive letter after the last "real" drive)
- Computer(2) chooses Drive A and Drive D in the ACC. Computer(2) now has
- the Disk-drives D and E, where D( Computer 2) is A( Computer 1), and E(
- Computer 2) is C( Computer 1).
-
-
- This is the pattern by which the drives will relate to one another as you
- select them. i.e. The drive closest to the begining of the alphabet on
- machine (1) (if it is selected) will be at least drive D on machine 2.
-
-
- Feature: The first virtual Drive is at least Drive D,
- otherwise the TOS thinks:"Aha, Drive C is there, so
- I must save my Desktop.inf there!"
- Which may not be usable for the other User...
-
-
- When you have finished editing the configuration, you can save it with
- 'Save Configuration' - Good advice!
-
- Now the work with Medium NET can begin.
-
- With Medium NET, You can now read from all of the Disk-drives on the
- other ST. And here is the best part, that someone on the other ST can
- continue to work as normal! But you are thinking, that the Data
- rate is about 2.5 KByte per Second and the Access is also
- relatively slow. But then again what do you expect for the cost of the
- Hardware (next to nothing).
-
-
- Beyond this you can still send a message to the other ST. However
- this will only be displayed, when the computer on the receiving end is
- running a GEM application. You enter your message in the Medium NET
- dialog and click on the 'Text send' button. If you wish to send a
- reply you also do this through the Medium NET dialog.
-
- Problems with Medium NET
- -----------------------
-
- The binding of the network software in the operating system is not
- complete and so it can cause problems that it cannot solve itself.
- Theoretically it is possible to Write over the Net. However should
- someone on the other ST write at the same time to the same drive, you
- then have total Chaos. Therefore one must not allow the opposite machine
- to write on your Disk-drive. This appears next to the read/write Button
- in the dialog. With inactive one can also turn off Read.
-
- One should never(!) open a file over the Net for Write,
- this risks the loss of the file!!
-
- One Problem also occurs with Read. This is namely your machine will
- receive none of the Media-Change messages from the opposite machine. I
- therefore generate at every opening of the Medium NET dialog a Media-Change
- for all of the drives that you are supposed to be connected with,
- therefore you should always open the Medium Net dialog and close it
- again before retrieving a directory off of a foreign drive. With a
- floppy disk change this is always necessary.
-
- It is somewhat frivolous to install Medium NET, when one only wants one
- File from the other computer (on the hard drive), especially if you don't
- want to bother the other person. But when one has one ST with and one
- without a Hardrive, one can now access the drive from either computer (when
- you don't mind it being relatively slow).
-
-
- Ah yes, one should also watch out for the partition size on TOS 1.0,
- as the Config-save transmits only the selected partitions from and to (Ask
- me why sometime...)
-

-
- PUBLIC DOMAIN
- =============
-
- LITTLE NET is PUBLIC DOMAIN and can therefore freely be given away.
- For the distribution of this Program, I am thankful to them.
- Distribute LITTLE NET but only with the complete File, also with this
- description included.
-
- On these grounds Medium Net is also PD. With respect to the grounds above.
-
-
-
- I'm sure you are thinking to yourself about how you could put the routines
- in this program to work in your own. If you would like to include them,
- then you must thank me with a 10 DM gift. When you do this I will send you
- a disk with more PD programs and Source-texts.
