	Set win 7 caused packet length to drop from the max of 9024 to
1289.  This caused throughput to drop even more.  On a certain file, it
was about 900cps at a packet length of 9024, and about 600cps with set
win 7.  With sz, it was about 1500cps. (v.32bis/v.42bis)
	All I know is that with zmodem, the RD light on my modem is on
continuously until the end of the file or an error.  With xmodem and
kermit, every so often (depending on packet length), the RD light goes
off, and the SD light goes on briefly.  This "turn-around" is what's
killing the throughput.  If sliding-windows streams the transfer as sz
does, then how do you enable it?  Because set win 7 didn't for me.  It
just shortened the time between the (agonizingly slow) pauses.
	I'm running C-Kermit 5A-170 locally, and 4E-070 is installed on
the remote machine.  Are these versions too outdated?

I have for sale one of the rockwell V.32 daughterboards for the
U.S. Robotics HST modem to allow it to be upgraded to a dual 
standard.  This board will work with most 14.4k round led model
HST's.  USR is currently offering it for $199.  I am selling mine 
for $100 inc. shipping.  $5.00 extra for COD.  If interested please

No it's not.  As a matter of fact, the commonly used modem modulations
faster than 300 bps are SYNCHRONOUS modulations.  The timing information
is carried along with the data bits.  Bell 212/V.22, V.22bis, V.32, and
V.32bis all do this (as well as a host of other modulations that aren't
as well known among casual modem users).

The only added cost for a modem is building in support for the RS232 clock
signals.  The modem-to-modem connection is already synchronized.

Dear Skeptics:
	For all of you out there you have been pondering on the idea
of buying an infotel 14.4k modem and have yet to here a reply on them,
here it is.  I have been using their new 14.4k internal (yes internal)
modem for two months.  It seems to do everything it is suppose to do,
even at $205.  It also comes with modem/fax window/dos communication
programs for which the fax program is the only plus there.  I get an
average ZIP file cpi of 1650 at 14.4 and 1024 at 9600.  On good lines
this will go up.  Although this modem was not advertised as containing
a UART 16550 chip, I was happily suprised that it did come with one.
The company, unlike supra, does not deal in vapor ware.  I called and
received my modem in two weeks.  For those of you only interested  
in external modems, their price is $259.  I highly recommend this modem
for those of you who, like myself, require speed and quality at half
the price.  If interested -->

here we go again.....

umm, some of us read *comp.dcom.modems* for discussions on modems (as
opposed to other groups).  but there's more involved in that discussion
than just questions about ``why doesn't my modem [fill in blanks]?'' or
``why am I being limited to xxxx cps with xxx modem?'' --- there are
other topics that *NEEED* to be here for the modem discussion to be
complete.  one of these is the set of technical discussions that pop up
from time to time (usually seem to evolve from something else).  another
of these is information about what's new and/or coming soon.

Toby has always been a tremendous resource to this group (at least, for
as long as I've been around here), and when, every now and then, he
posts this info on new stuff that's coming out, think about it in
relation to the above paragraph....  now, if the group degenerated to
the point that it was nothing *BUT* press releases on new products, I'd
be outta here.  but the odd press release every now and then is, IMHO,
not a problem, and quite the contrary, is a good thing.  suppose someone
happened to be interested in one of those?

[donning flame-proof clothing and turning on e-mail flame filters to
mention possible new group that may or may not be a good idea....]

the point is, it's reasonable to expect modem-related announcements such
as that in comp.dcom.modems.  now, if you'd rather move it to a .newprod
group, why not comp.dcom.newprod?  that way, the scope is more limited,
and it becomes more reasonable than asking someone to wade through a lot
of non-datacomm related posts all the time to find those few that are
datacomm products.

but short of something like comp.dcom.newprod, info about new modems
belongs here a lot more than in comp.newprod.  think about it for a
minute....what's this group's topic?

	Hello. I am curious about purchasing a V.32BIS modem that also has

	I am a sysop of a local bulletin board that has been operating for

Could someone post a listing of the Sysop programs that are available and
also give some advice about purchasing an external modem that will fit

So, what's the scoop?  Is Supra offering Sysops special prices?  If so,
what?  (I suppose I should call Supra and ask, but I don't have their

Also, people were complaining about not getting their ROM upgrades quickly.
Is this still a problem?

Thanks in advance for any info..

Oh yes, one last question: does anyone use the Supra v.32bis modem with
Hermes 2.0 BBS software?  Are they compatible?

Have you tried disabling error correction/data compression? If the

sent through to the BBS/host/whatever. Some hosts don't like that kind

The three pluses may have put the modem on the other end into command
mode as well.  Many BBSs disable this (or should) but some don't.  Of
course, if the modem on the other end is yours, change the command
recognition character or disable it.

I'm beta testing a product called Xview for DOS from NCD.  It has an optional
package called PC-Xremote.  It uses the xremote protocol which is supposed to
be more efficient than SLIP or other protocols when doing X over serial lines.
I just fired it up last night for the first time.  It appears to work well.  
I don't know if I'd do FrameMaker over the modem, but using several xterms to 
hack in seems fine.  There is mention of a rewritten xterm by NCD that was 
written specifically for xremote.  I need to get the source for it from NCD and
compile it.  The documentation for PC-Xremote says their x-term is more 
efficient.  It is my understanding that Xremote is included in X11R5.  Xremote 
is the helper program that runs on the host.  Xremote was included in the 
release of X we run on our Motorola 8840 (MPC) platform.  I'm not sure what the
cost of the product is.  I thing its around $350 for PC-Xview and another $100 
for PC-Xremote.  For more information you can contact the NCD PC-Xdivision at

I don't understand why Supra has all of these mix ratings. It seems that people
rate it anywhere from gold to garbage. Anyone have a reason why this is so?

I think it could be a number of reasons:

1. Supra doesn't supply any software with their modems(at least the PC version). 
   When I first got my Supra a couldn't get it to connect above 2400 with
   the parameters they had in the referance sheet. Their initialization string just
   didn't work for me. Maybe users have an incorrect initialize sequence.

   By not including ANY software, Supra is shooting themselves in the foot. Saving
   a few bucks on disks might cost them many 1000's of customers.

   The Mac version of the modem comes with software and a cable. How many mac
   users are happy with there Supra?

2. The particular modem might simply be "broken". It might be possible that the
   analog circuitry is below par for that modem. 

3. The Supra might be more sensitive to line noise or degredation than other 
   v32bis modems.

4. If 3 isn't the case, then maybe the phone lines in your area are poor. 


I find that once I got the modem going, it worked like a charm. I am not a heavy
duty modem user, so I can't say that I tested itthouroughly.

For the same reason that many articles posted to the net are positive:
the answer is that people use modems in many different ways.  I mainly
use the Supra to dial into the same terminal server every day.  About
25% of the time it fails to connect on the first try and hits on the 
second.  While connected it performs as expected, so I'm satisfied.

The people who have been complaining are typically using the Supra 
for more demanding applications like unattended uucp and dialing up
a variety of BBSs, and it should be clear by now that the Supra is
not the best modem in the world at negotiating connections.

Another factor (IMO) is that this most recent wave of price cuts
has brought many more novices (relatively speaking) into the 
high-speed telecomm game -- frequently with serial cards, cables,
and computers that are poorly suited to the application.  This is
unavoidable, and we'll probably have to wait for another generation 
of hardware and software before generic v.32bis modems are really
"plug-n-play".

You pays your money and you takes your choice ...

I've seen several reports that said people have been waiting weeks and
months for their ROM upgrades.  I never even received anything informing
me about the upgrade via US Mail, I only heard about it via this newsgroup.

I called the Supra BBS (and got through at 14.4 on the first try), filled out
an order form on-line for the ROMs.  I was in their database of warranty
cards.  I ordered the free ROM, and approximately 10 days later (or less!)
received the envelope with the ROMs, screwdriver, instructions, etc.

I didn't expect to receive it so soon--but then I also never received the
info about the upgrade being available, and a lot of people have said they
haven't received the ROMS after ordering them ages ago, so I wonder if Supra
is using 'random order' or something for sending them out.
