[comp.protocols.appletalk] AppleTalk over modems

Is anyone aware of a mechanism for implementing AppleTalk across
high-speed modems (such as the Telebit Trailblazer?).

In article <898@cadre.dsl.PITTSBURGH.EDU> you write:

There are a couple setups for doing AppleTalk over serial lines, of varying
speeds.  There is an 'Asynch AppleTalk' DA that was implemented at Dartmouth.
I know of two different companies doing serial ATP products; one is called
R-Server, I believe, and the other escapes me at the moment.  I do remember
that one of them had a 1200 baud modem built into it and was limited to that,
while the other could handle any serial speed.

AlisaTalk has, as part of its package, a serial<-->ATP driver that allows
any terminal program to function over AppleTalk.  Nice!

pcLINK from Pacer also implements soemthing of this sort -- unfortunately
it is restricted to their software only, but using their program and a server
on Unix I can mount a remote volume and actually have it show up on the
desktop :-).  At 12/2400 baud this is not very practical, but sure nifty.  
It also works at any speed.

Hope this helps a little bit...

We're using Shiva's NetSerial X232 box to dial-in to our AppleTalk network
here.  We're using 2400 baud modems, so it's pretty boring, but AppleShare
works fine.  Sending files to the LaserWriter remotely works just fine also.
The only thing we couldn't get to fly so far is InBox, which is a real minus
for us since we would like to drop mail remotely.  The January 1988 issoe
of MacWorld has an article detailing MacWorld's editorial office AppleTalk
and our remote connection seems to mirror theirs pretty much.  They are
using Intermail (nee Microsoft Mail) there with no problems, so I expect
that would work with the Shiva box as well.  InBox times out over the
phones lines, it seems.

At MacWorld I saw three products: the Shiva product line working
pretty well with a 9600 bps Microtech; Dataspace's unfinished product
that is working well with the Telebit; and Solana's R-Server 
which can be a gateway for a remote user or a bridge for linking
networks.  Phone is 619 566 1701.  These all look promising, as
does Project X from CE software, a wonderful email program that
allows you to make forms.  Cheap and not file server based.  Not
out until the spring.  Sorry I don't have the address, but they
are in Des Moines, Iowa.
