AV DSP Mini-FAQ v 1.01

Suppose you have a Fax-modem and you want to receive a fax late at
night or during your absence. Up to now the only way to do this was to
keep your Mac running at all times. No longer.

PreFax is a piece of hardware that enables soft power on/off Macs to
be turned on when the attached modem receives a telephone call (or fax
call). The Après Fax control panel shuts down the Mac after a
designated period of time if the Mac was brought to life by the modem.
Together PreFax and Après Fax can be used as an unattended fax
receiving machine.

New in version 2.0
Après Fax can now tell an extension manager (not included) to only
load the extensions necessary to receive faxes. PreFax 2.0 fixes a
problem on newer Macs. Newer Macs, and those running system 7.5.1 and
up, can be shut down by pressing the power key on the keyboard. This
had an annoying side effect with the original Prefax hardware. This
version contains a fix.

Dear Moderators,

enclosed please find an article I found on the usenet some time ago. It
describes how you can build your own appletalk compatible network connector
using only two or three condensers. Very easy, very cheap and works like a
charm.

The AT&T DataPort 14.4K modem has generated a lot of interest on the
newsgroup comp.dcom.modems. An external model of this modem with Class 1
fax capability (including cable and QuickLink II fax software, yech!) is
being advertised in MacWeek (3-08-93) for $299. The offer is only good
through April 30, 1993. If you qualify under the Sysop program, your price
drops to $222. In response to the question recently posted to info-mac, I
sent one reply but thought that it would make more sense to summarize the
postings on comp.dcom.modems and prepare a report on this modem.

I have clipped responses from the following people on comp.dcom.modems

This document contains information relevant to the AV Macs,
especially in relation to the use and programming of their DSP chip. It
is the product of my own experience and many helpful responses I
have received to posts I have made. I have taken slight liberties in
editing responses, so what you see below are not always the exact words
of the contributors to the FAQ. It is structured in the typical FAQ
format of question and answer with the questions listed at the
beginning. Please write me with any additions to or comments about this
document.
