Well, other than MNP5, it introduces no overhead. But it could degrade
throughput all the same, as it does increase latency (in some modems slightly,
but in some devastatingly), which has a considerable impact on block-ack'ing
protocols like Xmodem!

1000 cps is fast for Xmodem transmissions over V.32bis - many modems will not
get beyond an effective rate of about 800 cps at 14400 bps.

Block transfer protocols like old-style Kermit, Xmodem and Ymodem are hardly
suitable for modems above 300 bps - the acknowledgement will frequently take up
more time than the data transmission!

   Seems to me that the Courier 2400e that I bought March 20, 1987 used the
same power supply connector as the older Courier 2400 models, which predate
the 1987 time you mention.  Maybe it's also a poor choice on Apple's part
to use a connector that was used since 1985 as a USR standard connector.
   It _is_ unfortunate that the power supply fits where it shouldn't, but
one of the ways manufacturers keep costs down is to use connectors that are
already in widespread distribution and therefore don't cost as much as some
other "strange" and non-widely-used connectors (much less trying to invent
their own; you wouldn't _believe_ what that can cost!).

They do have FAX now.  If you buy a T3000 or Worldblazer now, you'll get a 
free FAX upgrade when it's available --- plus there is a $75 rebate on the

The TELEBIT CellBlazer is specially tuned for this application. I think
it is the only one of its kind.

The cellular connection differs from a regular telephone connection, in
that phase distortion is changing as the vehicle moves, even without
handoffs. "Normal" V.32 modems train themselves carefully to the signal
characteristics of the line, and then try to use all of the available
bandwidth, while assuming that the link characteristics don't change
under them. Cellular links change every few seconds, so you need to
maintain a MUCH larger margin, and be prepared to retrain more often,
but on the other hand the retrain can/must be done faster.

Flash ROMs are not the panacea users seem to think. 1 megabyte of flash
memory costs almost as much as a floppy drive. Even if you put the
microcode in flash memory, you still need an EPROM to hold the flash
programming code. (The very newest flash chips allow you to lock a "boot
sector" as you wipe the rest of the flash memory; this will help some.)

Finally, it becomes a lot harder to support customers if you have to
worry about customers bungling the code update end ending up with a dead
modem.

Organization: Box Hill Systems Corporation, New York, NY
Date: Fri, 6 Nov 1992 19:02:24 GMT

I've got a 1496E with 5.02 firmware, and have noticed that the modem sometimes
doesn't hang up when DTR goes off, even though I have set &D3.  This happens
when connected to a Sun IPX running 4.1.2 and the 1.4beta version of
MorningStar's PPP package.  I called ZyXEL's tech support in California and
the person told me that there's a delay built into V.42 (&K4) between DTR off
and hang up.  However, this behavior is reproducible without V.42 (using &K0
or &K2).  (The software was working fine with a Telebit WorldBlazer last
week.)

Has anyone seen similiar behavior?  Any ideas?

Thanks,
Tim

and have been able to download patches from their BBS.  Moreover, it is
clear to me that they are continuing to work on maintaining/fixing 
problems that still exist, or pop up under later DOS/Windows versions, with
their product.  After dealing with MediaVision for software support on their
multimedia upgrade package, Intel looks very good indeed.

Hi!
What you need is a ZyXEL! In the newer ROM Versions (above 4.06 I think) the 
ability to distinguish between FAX and DATA Calls has been implemented. 
You only have to use the Command AT#B1+FCLASS=6. In case of incoming Data 
calls the modem gives a normal CONNECT XXXX (XXXX=Speed). In 
case of incoming Fax calls you get a CONNECT FAX and the Word "ZyXEL" in the
next line. Now all you need is a software to start the appropriate Programs
needed. One example is "FrontDoor" available on Wuarchive and elsewhere. 
you can set a different mailboxprogram for every different connect speed if 
you wish. A friend of mine has exactly this setup running smoothly with
a ZyXEL, PC-Anywhere (remote-login on a Novell network) and rcvfax, the 
fax-utility delivered with the ZyXEL.
Ideally it would even be possible to use the modem as a normal voice phone-
answering machine, since this also is implemented in the ROMs, but the software-
support is still very rudimentary, so we have to wait for better programs 
or write them ourselves (if anybody has, please contact me...).

By the way: I have no financial interest in ZyXEL or any other of the named
products

Tom

I'm wondering if anyone has seen pcANYWHERE 4.5 or used it, and can comment

is definately right, especially with the Norton Anti Virus which I've 
used elsewhere and felt pretty good about, but I'm curious to see how
pcANYWHERE rates among users...

Also, I'm interested in knowing how well (if at all) it will work under
an OS/2 dos session.  I use OS/2 on my system, and would probably
be using pcANYWHERE to dial another system running the host program.

Who does that reach at Gateway?  Today I tried to extract an e-mail
address out of a person on the tech support line and got nowhere.
Guess I'll try it out and see.

First, you might try to find another asynch port, and use AT&C0&W to try
and make the modem come up with carrier enabled.  Then when you go
back to your dumb term, carrier should be on OK.

If you can't do that, or it doesn't work  (like &W doesn't work like
on some of the new cheesier modems on the market today),  then make
or modify your cable so Carrier Detect does not run to the modem.
Many terminals take an open circuit as a HIGH.  If that doesn't work
drive the CD line with DTR from the terminal.  Make sure that the modem
isn't still connected to the CD line if you do that.

On a 25 pin connector  CD is on pin 8 and DTR is on pin 20.
