I'm talking now at 38400 from my MacSE/30 to a Prometheus Ultima and I've
not seen a character dropped in about a year. The cable is full hardware
handshake. I run a v.32bis ka9q TCP connect every day at full 9600+bis
rate (which supposedly gets close to 38400 minus network overhead...though
I have never seen an actual data rate that approaches this). I used to run
mac uucp between Mac+ and Sparcstation at 57k baud (no modem in the way)
and got close to this in actual data rates. I think someone has a problem
with their modem design and doesn't want to admit it. If the mac can't
keep up it does not seem to have any problem saying so and shutting down
the hardware handshake line fast enough to not lose characters. If the
Supra on the other hand, does not a) understand, b) receive or c) deal
with the handshake line fast enough then...

I do not have a Supra so I can't say what is happening here but I can say
that my mac (at least) seems able to deal with these rates.

What terminal emulation package are you using? Perhaps the fault lies there?
I use microphone 3.0.

--alen
alen@crash.cts.com

ps there is a difference between baud and the data rate that the computer
sees, baud will define the maximim time it takes a character to arrive
at your mac. If your mac software can respond to this character by a)
buffering it and b) setting a hardware line if it will have trouble
buffering the next char (high water mark reached), then your mac will
be able to receive characters sent at that baud rate. You might see a
lower data rate however, since the hardware line may remain set for some
time while the software deals with the character(s) in the buffer.

I just went back and re-read the press release. It offers T3000's for
$499, with no mention of a PEP upgrade. Although there are other models
available with this program, it looks like it's not as good a deal as the
original Loyalty Pays program.

If the line has modular plugs you could use a 'y'. But since
some/many hotels/etc. don't have modular jacks you may have to use
other means. When I go to such places I carry along a screwdriver
and a telco cable that plugs the modem and has alligator clips at
the other end. Usually you can find a place to attach the clips but
when all else fails I've heard of people sticking ordinary sewing
pins through the telco wire the phone is on and attaching the clips
to that. 

Hope that helps,

Dave

The current version of firmware for the TrailBlazer and Fastlink is
AA3.01-AB3.00.  It has support for X/Ymodem, Kermit and UUCP "g" in
PEP mode.  It also adds MNP3 for slow speed error control.  The price
for that version of firmware is $124.

Pretty close.  Fastlinks began shipping in mid 1985.  The version with
V.22bis (2400) began shipping in 1986.  That's about 6 or 7 years.

Well, clicking is an awfully little thing, and there are plenty of excellent,  
pricey modems that click.  Telebits and some of the older Hayes modems for  
instance.  However, when you pay a lot of money for a good modem like a USR,  
Telebit, or Hayes, you are paying for big things like excellent technical  
support and a generally more compatible modem and not petty things like click  
noise, LED color/shape, etc....

Modem clicking is really insignificant.  It's like buying an Acura instead of a  
plain old Honda because the hood emblem is cooler looking.  I'm more concerned  
with the tech. support I get, how compatible it is, and how robust it is in  
operation (nothing is worse than having a modem lock-up and not noticing it for  
hours).  That's why I spent $500 on a T3000 and $750 on a TB+ many years ago  
instead of $300 on a Supra.... even if they click like crickets and have  
butt-ugly cases....  :-)

So the big question left is what *does* MNP10 ?

A new error correction scheme? Or "simply" an algorithm for handling
different line conditions like USR's ASL? It seems to be intended to
work with V.32(bis), at least it has been introduced with Rockwells
chipsets and a Microcom V.32 modem.

(I didn't know for one.)
Which reminds me that there are some modems around (I remember a
SmarTEAM 2400/MNP a friend of mine uses) that allow you to configure
"MNP block link". The manual stops there, just hinting one should not
use this option without appropriate software. I already suspected that
this block link mode is some ancient long forgotten feature of the
"original" Microcom implementation. Any info on that?

Really?  When I called Telebit yesterday, they told me that the Worldblazer

have Turbo-PEP.  

I wish someone from the company would post the whole story.

Has anyone noticed that the S37 register in the Supra v.32bis

set the highst rate at which the modem attempts to connect
with a remote modem...or so the document says...

If your DTE speed is x, you should be able to set S37 to force
the modem to connect all of the way down to 300 baud.  Regardless
of the DTE speed.

Page 53 of their manual is pretty explicit.  Too bad the modem
just doesn't work this way.

If you use the MGTS figures for numbers of modems and registration

All this information is neat trivia, but are we getting closer to answering

an Equinox 24-CS board.   I quote from thence:


"I talked with Equinox about specific cabling requirements given you have 
a fairly noisy environment (speaking of radio frequency noise) due to 
manufacturing.   So here is the deal:

	A. Using 24 gauge Telco wiring we should get up to 350 feet 
	running terminals at 38,400 baud. 

	B. Using 24 gauge unshielded twisted pair, we should get up to 
	1000 feet at 19,200 baud.  We may have to drop back to 9600 
	baud if noise is severe.  The following RJ-11 pins should be pairs:
        - 1 & 6,        2 & 5,          3 & 4.

If we have problems with noise on the long runs we might have to drop
