- Okay, here's the files that were missing from the "2.20"
- distribution on ab20. They're in amiga/s/mdillon (trying to keep Matt's
- file hierarchy, for some reason). The files in amiga/s/--dds are my
- files, the ones that I've modified and created over the years.
-
- You may note that a number of the files are concerned with using
- DNet over a Telebit Trailblazer modem in PEP mode. This is because
- there were a number of net.folks (including me) who wanted to use DNet
- over such a line, and couldn't figure out how to do it. So I borrowed
- a friend's TBit, took it home, and proceeded to experiment. If you are
- going to use a TB modem with DNet, note that the settings in 7tbit.set
- and 8tbit.set are the *ONLY* settings that worked! (This out of the
- near-infinite number of settings possible.) The Telebits were a bit of
- a dissapointment. Since they are asymmetric modems (i.e., 18000 bps
- one way, ~50-450 bps the other), it isn't possible to have
- bidirectional file transfers going with any speed. One way transfers
- are fine; the modem simply keeps the high-speed channel going one way.
- Trying to go both ways causes the modem to try to "ping-pong" the fast
- channel. This causes significant delays, and slows everything *way*
- down. I believe that any asymmetric modem (a USRobotics HST, for
- example) would behave the same way. (One of these days I'll get a
- v.32bis modem to try, and I can watch DNet just *scream*.) Interactive
- work didn't show much improvement over 2400 bps full duplex, mostly due
- to the retraining delays, I think. The data seemed to come in faster,
- but there were long delays between packets. Several times the whole
- thing just seemed to hang. It would eventually start up again after a
- delay of .5-2 minutes. I wouldn't call the experiments a failure;
- after all, I got the setup to work. However, I would have to say that
- using a Telebit isn't worth the effort.
-
-
- Okay, enough of that. Here's the list of files, and their
- descriptions.
-
-
- 7tbit.set
- 8tbit.set
- These are scripts for setting up a Telebit modem with either a
- seven or an eight bit data channel. Both set the modem to 19.2kbps and
- PEP mode. The files have *extensive* comments (like all but one
- line!). To use one, simply Execute it.
-
- DNet.Servers
- Remote-Startup
- dnet.config
- These are my own customized versions of the DNet files of the same
- name. I've included 'em as examples, more than anything else. Note
- that I put all my DNet executables in a directory called, "C:DNet", and
- I do an "Assign DNET: C:DNet" in my startup sequences. You could just
- as easily put them all in the root of a floppy named "DNET".
-
- amiga.tbit
- teksce.tbit
- These are the Telebit modem settings that seemed to work when I
- was testing DNet over a Telebit in PEP mode. (Teksce is the name of my
- Unix host at work.)
-
- StartDNet7
- This is a shell script to start DNet with a 7-bit data line (and
- over the modem).
-
- sdnet.old
- This is the 8-bit version of StartDNet7. It was originally named
- StartDNet; I changed the name when I wrote the WShell aliases.
-
-
- Shell-Aliases
- This file contains three WShell aliases for using DNet. One
- starts it, one starts PutFiles, and one starts GetFiles. To use them,
- you *MUST* have WShell and ARexx; both fine programs, and available
- from Bill Hawes. (plug, plug!)
-
-
- dnet.localteksce
- This file is a script for starting DNet which I use to connect to
- teksce over a direct line, when I bring my Amiga to work. (I did that a
- few times when I'd collected so much stuff off of the net that it was
- impractical to try and download it at home at 2400 bps.)
-
- I hope that this is of some help to you.
