"Discovery" modems are very popular in Germany. Discovery is just the
name of the modem line, the company's name is DATATRONICS, based in
Taiwan.

There are a lot of different models ranging from 1200bps up to a
vaporware V.32bis type.

Depends on the model.

The 2400C, which is *very* popular around here, just a plain 2400bps
plug-n-play modem is pretty reliable. I have had one for two years now,
and it just works, never gave me any trouble.

Some time ago I took a close look at the 1200C's controller code, and
lost all my respect for professional programmers and modem manufacturers
:-)

The <9600bps models all seem to be based on Sierra chip(set)s, there are
also 2400/MNP and 2400+FAX models around.

The V.32 model, "9632AM" I think, claims V.42 compatibility but only
offers MNP2-5. Also it seems to have trouble even with that. (From what
I've heard, I don't have one myself.)

The V.32bis isn't available yet.

   i have heard the same rumor here in Las Vegas as well.  this noise problem
is all over the valley!  i field complaints on wet days, dry days, windy days,
from late night and to early mornings.  who would take me serious if i suggest
that the local telco go out and clean-up every junction box in town?  who is
going to police the neighborhoods to insure that the junction boxes are not 
being saturated with water?  it would be great if the junction boxes where
designed to be water/dust proof or if the zoning commissions would require 
that the boxes be placed in areas free of sprinkler systems, but the telco
does not have the money to clean/dry out the boxes; the boxes and sprinkler
systems are already in place and would cost too much to move; zoning commisions
flow where the cash and investors flows; the boxes are designed to perform a
specific function -- environmental niceties cost money that the telco are not
inclined or required to purchase unless specifically designated by some
authority.  and i still get Directors, Professors and students complaining 
that "I" should do something about this or that maybe someone should be hired
who knew what they were doing in this area.  what i really need is a few good
managers that can take the facts as i get them and start solving the problem. 

  i have come to realize that the problem i in see in Las Vegas is a small part
of a growing problem -- a breaking down of the telecomm infrastructure at the
local level.  i still would appreciate more comments on this noisey line
problem with modems -- my boss is not inclined to hear about solutions that he
has no control over, i.e. telco.

Subject: Supra, ZyXEL or ZOOM ???

Well, after reading all the postings, I am both VERY much enlightened but
also faced with confusion about which modem to go for. My current favorite
had always been Supra but it appears that ZyXEL and Zoom ( though newest )
have very strong support. I'm definitely going with a v32.bis 14.4 modem.
The questions are :
1: what are the favorites among the netters here? Supra, ZyXEL or ZOOM ?
2: what kind of chipsets do they use, and if that really matters?
3: Do all 3 models support fallback, or speed change when the line quality
   changes ?  I read that the Supra doesn't in an earlier posting...

4: What's a good place to buy. I only know of Computability for the Supra
   and Direct Micro for the Zoom. To be honest, I only heard of ZyXEL a few
   days ago and haven't had time to check the C. Shopper for a dealer yet.

Any answers will help, please post or e-mail me direct, I'll post a summary
if there are abundant replies.

Thanx in advance.

If you mean netfax from mit for unix, then I had to hack it to use
hardware flow control on another fax modem... the symptoms were lines
being jumbled, and the image was stretched.

"Class 1 and 2" are modem command sets.  "Group 3" is a fax protocol.  These

V.32bis modems do indeed contain 9600 TCM and 4800 bps modes for backward
compatibility to V.32 modems.  The training and rate sequence exchange during
a V.32 or V.32bis handshake occurs at 4800 bps...

Wait a minute.  I thought that v.32bis gives 38400, and plain v.42
gives 14400 bps.
 (even modem ads seem to differ on facts, leaving me even more
confused)

Question:  Is HST (which yeilds 14400 bps...I think), the same or at
least compatable with v.42 (or v.32bis which Ray says....or what ever
the hell gives you 14400 bps)

I'm not sure if this is the right newsgroup but...

We have written a program that is SUPPOSED to be compatible with uucp's

successfully doing this is that a number of crucial details are
ommitted from the AT&T documentation.  The most important one is the
amount of time to wait for an expect string that apears in a Dialers

be very helpful to us if you could pass it on.

No.  The T3000 modem is the first of a family of modems which can be built using
the same hardware engine but different firmware.  The 2nd in the family is
the newly announced WorldBlazer, which is what we have all been calling the
T3000 + PEP, T3500, etc. for the past few months.  

When you receive your LP firmware upgrade, you will also receive a new 
faceplate 'transforming' your T3000 into a WorldBlazer.  It is likely that 
there will be other new modems based on this hardware engine as well.  
(Possibly with FAX capability?)

I'm no expert on this stuff, but I do remember reading somewhere that baud
IS Bits per second.  That would lead you to believe 2400/8 = 300 Bytes per
second.  However, each byte sent through a modem is padded on either side
with one start bit and one stop bit.  (i.e. start bit + 8 bits + stop bit
equals 10 bits)  That's why actual speed is 240 characters per second.  I
don't know why, but I'm pretty sure that's the way it is.  If I'm wrong,
someone let me know.

   You misread; the above statement does not refer to plain 16450s.  If your 
16450 is soldered in, then you may have a difficult time removing it without 
damaging the PC board (my usual advice is to pulverize the 16450, leaving only 
individual pins that can be removed easily).  On the other hand, why not 
install a 16550 on the second serial port?  You may need a couple of 1488s 
and/or 1489s, but these are inexpensive chips (unless you buy them from Radio 
Shack, and even then they won't break the bank).

   Most PC owners have only one high speed modem and can thus get away with 
only one 16550... there's no need to risk destroying a good serial or I/O 
board.

I don't think that is what Greg means.  I believe that when you buy the
V.32bis and PEP modem, you will get a T<new number> and when you change
the ROMs to get PEP in a T3000, you will effectively end up with a
T<new number>.

That's not correct.  Telebit will make a different model modem that has
both PEP and V.32bis.  The model T3000 will continue to be a V.32bis modem
without PEP.

most other computer communication capable of doing this?  Right now a group I
am working with here in Omaha needs to use data compression modems on a
Lantronix terminal server with DTE speed locked and DCE link throughput
floating.  This requires some kind of flow control to avoid overflow of the
modem's buffers, but the Lantronix does not have wires for RTS/CTS and we
need an 8-bit clean path accross the link.

	Second question, what is X.32 and what capabilites would it give
to implimenting a low throughput SLIP network over the POTS?

	Thank's in advance for any info,

P.S.  Please e-mail your answers as I can not read news too often.
