For a cheap solution for incoming calls on two lines, you might try Radio
Shack's "Answering Machine Two-Line Adapter", part no. 43-383, $21.95.  It
allows a receiving device (e.g., answering machine) to switch between two lines
when a call comes in.

That connection appears to remain in effect until the next incoming call on
the other line, i.e., I don't know of any way to select the line for an
outgoing call using this device.

Yes it can be done.  As a matter of fact there was a company in
Washington state - I want to say MicroConnection or
MicroPeripherals, or something similar - who made a 300 bps
auto-answer modem in the 1980/81 time frame.   

There was a port on the modem with a mini-phone jack.  You
could 'transmit' a program to tape, mail the tape, and the far
party could play the tape and 'receive' the data.

In the early 80's phone calls were more expensive and to move
large programs over phone lines got a bit expensive.  And this
was cheaper than diskette often-times.

It also permitted exchange of ASCII data among non-compatible
machines - which in those days were usually TRS80 Model I's,
Commodore PET's, Apple II's and a flock of S-100 variants.

You can't directly control the number of rings...but you can control
the time in seconds.  The standard ring signal is 2 seconds on, 4
seconds off...10 rings can get through in 60 seconds, so set ATS7=60
if you want to wait 10 rings before giving up on a call.

for years and give it a try. It worked! Since the online registration

dropped into my mailbox every so often. Today I received a booklet

Dallas Fax tech suppor STINKS! They only have two guys working in the
dept and only one of them is semi-knowledgable... I have a Dallas Fax
2496P pocket fax modem and there is a v.42bis connection bug that
I am trying to get a fix for. Whenever you try calling another
V.42bis/MNP5 modem, it ALWAYS connects in the MNP5 mode.I have played
around with the AT\N4 and AT\N5 options with no luck. However,
when I try the other direction and have a HST with v.42bis call
the Dallas fax modem, the connection is made at v.42bis!! Very strange.
This same problem also exists with GVC modems. We also have a GVC
FMM 9696 mini external fax modem with Version 3.0 firmware dated 11/91 as
reported with the ATI1 and ATI3 commands.

BTW, the dallas fax 2496p modem has the following firmware as reported by
ATI3:

MICC 9/3/91-1.0C PKT-F 4K

Did anyone notice that Dallas Fax has stopped advertising in computer

  Supra's customer support, to put it bluntly, sucks.  I demon-dialed

gave him a special number.

No, you're using the modem in the Conventional Command Mode, which
won't give you direct access to the registers necessary to turn on
V.42/V.42bis.

The Conventional Command Mode is intended only for software that can't
be configured for anything but a "Hayes compatible" modem.  If your
software can be configured (initialization string and connect strings
can be customized), then you really want to use the Enhanced Command
Mode.

You don't say what operating system you're using, but here are the
modem settings for Unix:

&F Q4 X0 S51=254 S52=2 S54=3 S55=3 S58=2 S66=1 S95=2 S97=1 S106=1 S131=1

For most MS-DOS programs, use the above settings except for Q0 X11.
Note that these settings use 19200 bps on dial-in, so set your software
to 19200 bps.  They also use RTS/CTS (hardware) flow control, so make
sure your computer will also use RTS/CTS.

The phone number is in the chapter on troubleshooting, and it gives this

  Hello.

  If anyone from Zoom Telephonics is listening and would care to answer
the following, I would be appreciate a response.  Obviously, this is
likely not a part of your job, so I am looking for someone with net access
who just happens to like answering questions in thier free time.  :)

  What is the current ROM version, and are there any plans whatsoever
to update them to add features, or improve the long distance stability
of the Zoom modems at high speeds on lousy lines?

  I have found that setting S95=47 often makes the modem connect much
more easily, even though this is only supposed to affect the reporting
of connections, not the way it makes them.

  By the way, if anyone has translated the PC only addenda to the 
Zoom manual to an appropriate Mac set of conmmands, (to encourage a 
retrain) I would not mind getting a note.

  By the bye, I have tried to get to Zoom Tech Support.  While I did
not try as many times as Mac User did in thier article last month (50),
nobody picked up on the 15 tries I did make.  I figured that netreaders
would be more likely to know and answer such questions.

  Please reply through E-mail; my link to news is long distance, so I
often miss articles.

  Thanks much,

	Seeing as how sysops are free advertising, I suspect they did.
I know I do similar things in my own DMBS work.

	One thing: I wouldn't know *how* bad or good Supra's customer
service people are -- I've not had to call in four years of owning their

	Ahem, sorry again. The SUN my friend has is using Version 1.0 (or 1.x)
of the PROM. They're up to version 3 or higher by now (I'm not a SUN maven,
so I'm not exactly sure).
	To reiterate, my friend is getting lost data on his SUN with a DTE
speed of 38400 to his WorldBlazer, while talking to my WorldBlazer on a 80486
33Mhz running Consensys SVR4 (thank god I've never needed support) with the
DTE speed at 115,200. He also loses data when he does an AT&V (register dump)
so it's not my machine. This is either (supposedly) a known bug in SUN proms
or (I've heard it said on the net - which doesn't mean anything) that the
SUN does not support incoming hardware handshaking. Or else, he needs to add
some CLISTs to his kernel. (His SUN is a Sparc I)
	If anyone has had this problem and solved it, please let me know!!!
Or write to him as yale.edu!admiral!kilowatt!VanGogh!bartek

Well, that does of course depends on what you mean with "compressed". 
Different methods have different efficiency. If you do some simple RLE 
compression, the output file would be "compressed", true. But you can still 
compress it much more, with better algorithms, such as LHA or ARJ style 
compression.

As he didn't indicate what types of compression the pre-compressed files were 
compressed with, it could be possible with 1850cps if he were using some less-
efficient compression, such as ARC (not any of the new commercial versions).
V.42bis would then still be able to compress it just a little bit further.

V23 is an old CCITT modem standard, used by the variuos european prestel

Not by a long shot.  He did invent the class of convolutional codes that
evolved into the channel coding method used in V.32.  He also led (kicking

application of forward error correction to the voice bandwidth telephone

the inventor of the code actually used in V.32.  Lee Fang's contribution was
the creation of "rotationally invariant" codes using the set partitioning

Ungerboeck's contention, at the time, that rotational invariance was not

Hi there,

has anyone ever seen a real *working* ZyXEL 1496E? I bought one a
week ago from a dealer (supposedly at distibutor (?!?)) in Bonn.
It didn't work. After half an hour, it just crashed with the LEDs
in a random state. Power cycling (the only way to reset) didn't 
help. I took it back and they exchanged the power supply.
Second try: it worked for half an hour again, but then ...
Now they swapped the modem for a new one (supposedly, at least).
This was said to be the last one they had, new modems coming in
4 weeks...

Everything is fine now: the self test works, and I can configure the
modem from my computer, store tel. no. and such.
If now it only could dial........
It cannot pick up the phone and dial a number, just says NO DIALTONE
and the speaker remains silent.

I made the decision the buy a ZyXEL, which is quite a bit more expensive
than other modems (798,-- DM vs. 499,-- DM for generic V32bis) because
from reading this newsgroup I got the (obviously wrong) impression
that it was worth it and that I'd get a quality product. Not too much
quality in there; they use a 12 Mhz CPU clocked at 16 MHz and 150 ns
EPROMS whereas somewhere I read 120 ns was required.

Totally frustrated,
