A couple of weeks ago, Matt Dillon was kind enough to send us a DNET disk
ready to go for multiple serial ports (using the ``specify driver and unit
number'' method). Getting ready for AmiExpo in New York, we've had a
chance to fire up DNET on our expansion serial ports between two A2000s and
would like to share the results with you:
o DNET works perfectly over our serial device and drivers.
(With no modifications).
o Performance was quite reasonable for file transfer. On a
31250 baud line, files transfered at approximately 23000
baud.
o Performance could clearly be higher if a transfer program
was used which didn't have to animate the CLI cursor and
printf the progress messages.
o It is time for Matt to allow arbitrarily high baud rates
as right now DNET appears to stop at MIDI (31250).
I think we'll be busy stringing serial cables around the office in the next
few weeks as DNET provides a viable inexpensive file transfer capability
for an office environment. We're looking forward to Matt's proposed future
enhancements which includes email.
We'd like to see someone add a ``repeater'' capability so that a simple
star or point-to-point many host network can be achieved.
We'd like to say: ``Way to Go Matt!.''

I don't get this. I like dnet a lot, use it all the time, and so on. But adding e-mail clients/servers to DNET? try to turn it into a general protocol stack? Use it to hook up lots of amigas in an office? Why on earth when we have all the free tcp/ip implementations available, with host name resolution/packet forwarding/error handling and all those other ugly issues resolved? DNET is terrific for going from an amiga to some host and getting a nice IO mux. I use it exclusively from my home. DNET does not make sense as a general purpose networking system, unless you want to add lots of changes. Then the amiga has a protocol with total incompatibility with the universe. Just what we need, another point of difference. At some point it looked like Ameristar was gonna release SLIP support, but i guess it never came to pass? Rick? (hmmm, Rick may be over in Next-land by now ...) In any event, if ASDG is going to put time and effort into putting good networking software out using their serial card, i hope they pick the standard which buys interoperability (horrible buzz word, good intent) with all the other networks that are out there. ron

Hear, hear! Sticking with standard protocols would help sell your hardware
(and Amigas) in the educational/research environment, Perry.
BTW - after all my earlier bitching, I'm going to order your new serial card.

Hi Ron, No, I am here in Amiga-land :-) We are starting to see some nice standards work on dialup SLIP, eg CSNet's version, so we will be dusting off our plans to market a SLIP based product. My early plans to market SLIP were placed on hold after it became apparent that there were several versions of SLIP out there that were potentially incompatible, and that there were no standards at all in dealing with dialup SLIP. I'll have this out after Siggraph, along with a boatload of server side applications. We will make our SLIP driver configurable enough that it will be compatible with third party serial products, such as the ones from ASDG. I find the prospect of inexpensive third party serial products very exciting in that it will provide an inexpensive way for people to buy into our upcoming NFS based peer to peer network technology. BTW, I would point out that at least some of the packages that are commonly identified as "public domain" in fact are not. For example, the KA9Q package is not commercially redistributable.

Everybody catch this line ? I think this advance on the current Ameristar technology is going to be very significant for the Amiga. I'll hold the applause until we're running it here, but, very nice move, Rick! > Rick Spanbauer > Ameristar Technology andy -- andy finkel {uunet|rutgers|amiga}!cbmvax!andy Commodore-Amiga, Inc.
