Interesting...the Conexant HSF series are softmodems (while the HCF series are controller-less winmodems).
The only document I could find concerning that specific chip model was for an internal PCI softmodem.

There must be another chip in this external modem doing the processing then?

By the way, I saw this modem at Office Depot and the box said "Accent Communications - Powered by D-Link." So I guess this is a D-Link product. H/W revision on the UPC label was A1.

Yes, I see the D-Link with the same chip on it in other countries but not here. I think it's supposed to be some kink of a DSL modem but DSP chips can do just about anything with a signal if you program it correctly.

I have also seen some messages about poor performance of the "cant break the 33k ceiling" kind. First ones that set up and log on please share your experiences.

That's a controller-based (hardware) modem chip all right.

This looks to be the D-Link DFM-562E in a different external casing (same chip and features).
Here's the link to the drivers and manual at the D-Link international site:

As for firmware, the Russian D-Link site has a firmware update for the DFM-562E (in English):

Amigo.com.tw, BestData and Zoom have 6827 based modems (I have bot an Amigo/Cendyne and a BestData so this will be my third such modem in my collection) - I flashed my Amigo/Cendyne with the Zoom firmware which turned out to be not a good idea. But the sites do have documentation that may prove useful. I've got the firmware (which is pretty generic) for the Amigo/Conexant if anyone wants to try it. I've found that using a ; as a delimiter between compound commands (like the S=, +MS=) helps them work better. You will want to use the +MS= command to get the best out of v.92 at least whatever your ISP supports of it.
. Getting the MOH (Modem on Hold) feature working has been an adventure in frustration for me - I ended up using a Catch-A-Call box.

If this is a hardware modem (which it should be), why does it say it requires Win98 or higher, a Pentium 233MHz with MMX support, 64MB of RAM, etc. ? Strange...

The OS requirement is for the bundled software and drivers NOT the modem itself. The modem will work with whatever OS you have, it's just that you will have to know (or learn) how to use the modem commands and set up the serial port yourself (stuff that is at least partially done by the modem drivers for Windows) to get the most out of it.
. Don't forget to set the serial port to (at least) 115,200 in windows too if the drivers don't do it (check in device manager to be sure). And there is a neat utility out there to increase performance of some serial port chips like Winbond and National Semi, etc. - it's called SHSMOD. It's not hard to find if you want to try it. They are on a web site in Japan, but there is an English version of the site too, so don't fret.

Picked up the last one at my local OD this morning. The back of the box says "External Modam". Guess someone didn't screen the graphics before signing off on the packaging artwork Nice deal; thanks !

External modems can be winmodems/soft-modems

Anytime the Systerm Requirements or OS Compatibility lists only Winflavors, it's a winmodem.

Anytime an external 56K modem still in production is this cheap, it's a winmodem.

Ok, Linux too. Any OS that uses a driver and the CPU to function as a data pump is a software based modem.

If it were a hardware based modem, you could use DOS to dump data to the serial port and the modem would do the rest.

Someone wanted to know the manufacturer. The inf suggestion is a good solution. You can also try typing AT#MFR? in any terminal software or a DOS prompt if you know how to send commands directly to the COMport the modem is on.

Unless they have boxes labled for Mac and others for Windows in regards to the bundled software, the only reason the salesman needed to know what OS you waned to use the modem with is because it's a Winmodem.

The items bundled with a modem change throughout the modem's production life.
The picture on the box may be old and not actually the modem currently packaged.

The manufacturer may change the software bundled with the modem.
Unless the OS requirements on the box specifically mention that they are for the software bundled, those OS requirements are for the hardware (the modem) and it's a softmodem.

HSFI is a soft/win - modem
Conexant is a bunch of old Rockwell managers and some engineers who bought the modem division from Rockwell when Rockwell wanted to get out of the business.

MOH requires you to have CID and CW (not just CID).
You need an MOH applet from the modem or chipset manufacturer to support CW tones in the driver. If it isn't bundled with their driver, check their website. Since it's a V.92 modem, their should be an applet for it somewhere.

Note that a chipset may support a feature but not have it enabled.
The company whose box you're buying the modem in may have bought a cheaper reference design of the board that uses the same chipset as a higher feature modem but have those features turned off in the chipset or maybe lacking hardware or EPROM code to take advantage of those features even if turned on in the chipset.


$50 could possibly get you a cheap hardware based modem these days.
Unless they are dropping a manufacturer or replacing the model, I don't see why a hardware based modem would be blown out the door for free.

I hope you guys get a hardware based modem but all indications other than MAYBE the original price point to it being a softmodem. Many hardware based external modems still go for $80. The Conexant HSFi-CX11251-11 is a softmodem.

Good luck!

Wrong! Wrong! And wrong yet again! (Props to Bobby KKK Byrd!)

My what an interesting bunch of hoo hah... (Watch out when in the cow pasture that you don't step in the hoo hah.)

We have found out from several that this OD modem is based on the CX-06827-11 just the same as two of the other external serial modems I have here. ALL external serial (RS-232) modems are full hardware modems as there is (at the usual 11.52kBytes/sec max) just not the bandwidth on a standard serial port to operate as a softmodem/ Winmodem.
. ALL USB external modems ARE softmodems or Winmodems as there is the bandwidth on USB for it to work - but they are to be avoided as they tend to load down the CPU overmuch.

. The reason that the Windows requirement is listed on the box is just what I said in my last previous post. The drivers and software included (such as terminal/fax software like Bitware) is all for Windows. All of my CX-06827 based modems work fine with DOS, Linux, OS/2, even with the Windows generic driver, etc. And I didn't pay much over $20. for any of them - I haven't spent over $30. on an external serial modem in at least 5 years. I'm hoping against hope that the OD one will be a better implementation of the Conexant design.

. How far the once-decent BestData has fallen that it's modem doesn't work better than the Cendyne branded Amigo generic with the same chip.

. Perhaps I'll complete the grand slam and add the Diamond Supra (now part of BestData) to my collection as this is probably the last generation of RS-232 serial fax/modems. And at $14. you know you can't stop at just one...
. The tide is definitely to broadband and they are even doing away with the legacy serial and parallel ports on the mobos. A big mistake IMO, as they are still very useful for real-time data collection applications.

.bh.
(user of external serial modems since before 300 baud was considered the HOT ticket!)

And just for completeness, MOH does NOT require CID (Caller ID) but it may require what is called "Enhanced Call Waiting" in some service areas. The only time CID is required is if the the software that comes with your modem does CID and you actually want to use that software. But that particular feature is usially only found on PCI soft/win modems.
Most external serial modems are hardwired to ignore the CID packets. .bh.

Yup, all external serial modems are hardware modems; just like this one. As for the listing on the side of the box that only shows Windows products, manufactures often list only those platforms they 'officially' support. It doesn't mean other platforms won't work with the product but it does reduce their support cost when someone calls in with an officially unsupported platform. For example, I have an old USR Mac external modem. The unit clearly says MacIntosh but I've used it on a Windows PC with a generic driver. In fact, one of the big advantages of an external hardware modem is that you often don't need special drivers - most external modems will respond to AT commands from a generic/default driver.

Yep, this is a hardware modem but it doesn't work as well as my PCTel softmodem. The PCTel typically connects to my ISP at 54.6 K. In about 10 connections so far the hardware modem has not connected higher than 49.3 K. When I've tested the download rate the PCTel often delivers more than 52 K. The hardware modem languishes in the 45 - 48 K.

If it doesn't perform better what's the point? More wattage, more cables, another power supply. Nothing magical about hardware modems except they may offer an opportunity for use with other OS.

I'm gonna return mine.

Great! I'm glad it turned out to be a hardware based modem for those who picked one up.

Constant Mesh, you could make some AT-Command adjustments to possibly improve your connection rate if you'd rather not return it.

No hooha here! I don't think this area is zoned for cows. My post was in responce to someone's earlier post that ALL external modems are hardware based. Your own post agrees that there are external USB softmodems.

Yes, the 6827 is in our hardware based modems. I didn't say it was a softchip.
Someone posted that it came with an 11251-11. I confirmed that the 11251-11 is a softmodem.

Of course a hw based RS-232 modem can work on a Winbox, Mac, etc.
Since the dawn of winmodems, OEMs have tried to keep the softmodem fact off the box.

Only the modem requirements and features that are intended to be included/supported throughout that model's production life are listed on the box.
Everything else is added with a sticker or flyer insert. Included software and it's features change over time.

A sticker used to denote if the bundle was for use with Windows or Mac.
The modem came with software for one or the other.
OEMs sometimes contract with a retailer or deistributor to support the modem on one or the other only. Just the same, if you contacted us, we'd make sure the modem was funtional regardless of what system you used it with.

Sometimes OEMs bundle both Win & Mac software in one box.
If only one or the other was offered and as long as a cheap deal and special serial number was not issued for one retailer/distributor as I menionted above and someone posted earlier, endusers could request any OS software the OEM made available through Customer Service, Tech Support or Sales.

As for the box, I can only speak from my experience. Other companies may be at different stages or may just not care. We used to list requirements and features of the modem and software without detailing which applied to the modem and which applied to the software. That caused legal problems. Endusers didn't want to use the bundled software but expected the listed features from the modem even if they stuck with their old faithfull software. We had to detail what were modem/software features separately. Finally, we reduced software specs to a minimal with a disclaimer printed on the box that software features required use of the bundled software. Those features could change with future revisions or substitutions. A sticker was afixed listing the featured software and only a few basic features of what the software could do.

Your probably right about MOH. I haven't worked with it for quite a while. Back then, Enhanced Call Waiting was hard to come by separately. Companies that marketed CID often included it. If a carrier offers ECW, it would be conterproductive not to offer CID. There's a bigger market for CID. Any carrier that offers CID and lacks ECW and other V.92 features by now is somewhat substandard.

I don't recall seeing any modem list ECW support as a selling feature. Usually CID and other V.92 features are listed to market to the masses. Requiring ECW is usually in the product's white paper from the manufacturer of the board or software that supports it or possibly in fine print in the manual. I suppose some manufacturer may include "CID software requires ECW for MOH". I don't know of an OEM who supports or reccommends MOH without use of their software but I suppose it could be done. As you mentioned, a hardwired modem is just a conduit that passes the data through. OEMs supply an applet to tell you who's calling and to allow you to MOH. I hope you can get it to work. Everything changes from rev to rev and from manufacturer to manufacturer and can sometimes be tweaked later if not now.

I didn't challenge or contradict anyone.

Just to make my post clear: I read the chipset ID from the manual for the modem located on the CD-ROM included in the retail box. It lists the chipset as Conexant HSFi-CX1125-11. I did NOT look at the PCB directly, or run any diagnostic program. Just read it as it is written in the manual.

Well, I just got mine and wasted no time in opening it up. This modem is magnificent - much better than the external modem from BestData (which sells on their web site for $54 and you can get free shipping and web acceleration software along with it.). The package does include the data cable and phone cord - both are listed right on the box! And they are wondering why they didn't sell... :roll: Easily worth the asking price of ~$50. Their pain - our gain!
. It is based on the Conexant CX-06827-11 HCF chip as mentioned earlier. This one has a power switch and it has the voice support chip so your voice-mail applications will work (the BestData lacks both, the Cendyne/Amigo lacks the voice chip but didn't remove the code from the firmware so software gets confused and installs the voice mail functions). It also has mic and speaker jacks on the back so you can use a dedicated mic and speaker or run it thru your sound card for voice functions.
. I keep Smith Micro's Hot Fax Message Center on my PC for the fax capabilities and it will be nice to try the voice mail features of it - been a while since I had a D/F/V modem.
. It is supported by D-Link!!! It also comes with "interesting" (the Chinese meaning) software for data comm, fax and voice mail from BVRP in France (the same one that supplies the MOH software for the Conexant chip that I've never gotten to work) - so use it at your own risk... . IAC the version on the CD is old and does not mention XP so I would suggest NOT installing it. Instead, go to the BVRP and/or D-Link web sites to see if there are updated versions of the drivers/firmware/software available.
. Or you can make the wise choice and visit your favorite software reseller and order HotFax Message Center 6 - it can handle all your communications except for the internet (data-comm, fax, voice mail, internet fax) with much less overhead than WinFax which only does fax. Support your American software companies!

. Anyhoo, it looks like those of us that got in on this may have got a weener. Pat ourselves on our backs!

. I'll be logging out now to install it. Keep your fingers and toes crossed!

About the best feature of an external modem witch no one here has mentioned is the status lights. I know you can get a softmod for an internal modem to display on the toolbar, but I like the real thing!

Unless this modem is so cheap they are not including them, yes, I have actually seen a external modem that had no leds on it.

For what it's worth... More technical info and command lines to use to maybe make the modem faster?

Well, I'm back and it logged on first time at 46.6 which my other modems get maybe half the time (the rest of the connections are at 45.?) if I'm lucky (even with the extra commands for v.92). I'm at least 10mi. from my ISP's nearest PoP. Even the speaker sounds better than the ones on my other modems. We did good!!!

. I just need to find out the way they chose to implement the "+MS" command for it (there are two ways). If anyone locates the AT command summary for it, LMK right away! Ditto on updated drivers or software.

Thanks,
.bh.

Yes, it has four green status LEDs -- power, carrier detected, receiving & transmitting data.

I wonder if the serial port's maximum data rate is a limiting factor for this modem with its v44 compression scheme? This may be a disadvantage of a serial modem as compared to a PCI slot softmodem.

Yup, four status LEDs are all that the 06827 supports. I have the 6827 tech manual here if anyone wants a copy.

It's not really a limitation (as 56kbits/sec is about one half of the serial port speed of 115.2kbits/sec - be sure to go into DevMgr>Ports>Com?(the one you have the modem connected to)>set for 115,200 or higher and see what happens) but if you have the right kind of port on your mobo, you can use SHSMOD to crank up the port's bit rate to over 200k which can make things seem a bit crisper (even if it's only in your mind).

I have been unable to locate an AT Command Reference for this modem, but I did find out the proper site to go to for what info there is on these modems, (accent.dlink.com) which isn't much. So I have their CSRs running around hunting one up for me - I'm sure that is about as kind as sending a naive nurse-trainee off looking for a sterile fallopian tube... Tsk, tsk that's downright mean.! .

p.s. I'm going to see if one of the moderators will move part of this into a new thread in an appropriate section as this doesn't need to be continued any longer here. As soon as we "Get 'er done", I'll add one last note with a link to it. Come on along until we have these babies humming. bh.
