I just bought one (the external) and have no problems with it.  I have
connected with MICC and Multitech at 14.4Kbps with no problems.  I have also
connected at 9600bps with an unknown modem type, but had to force the
Forval to 9600bps.  The auto-negotiation mode gave up, so had to force it.
The 9600bps modem must be an older type, since it does not have V.42/V.42bis.
It has MNP.

Juicy gossip:
I have read on RIME net that Forval will soon no longer be selling the
modems.  The Forval modems are actually made by Intelligent Modems Inc.,
and sold under the Forval name.  In the future, IMC will no longer sell
them through Forval.  (I suspect that is the reason for the current sale
price of $275 for internal or external.)  But IMC will still make them and
support the Forvals as well.  Forvals are still supposed to be supported by
IMC, as they currently are.

Updates/Upgrades:
Updates (bug fixes) are FREE.
Upgrades (new features):
	FAX upgrade due this year and will be FREE.
	Forval unique 19.2Kbps rate due within 90 days for $100.
	V.FAST is supposed to be achievable when spec is finished for $???

Both types are accomplished by calling the factory BBS and putting the
modem in a special mode to update it.  No PROM to replace, so update must
be to EEPROM or battery-backed SRAM ( I don't know which).

I have read that some people have lost updates/upgrades, probably due to
powering modem up/down.  If they leave them on, no problem.  This is not
catastrophic, as the original code is in PROM, and is not lost - you just
lose the updates.  I haven't had any experience with this, since I haven't
updated - I have the latest revision in PROM.

I just bought a Twincom V32bis 14.4 Fax/Modem and I haven't been able to
connect to the Prodigy information service since. The Prodigy communication
program tells me that I have a noisy line. Also, the prodigy service runs at a 
maximum of 2400 baud.

The manual that came with the modem suggests using the AT command W2 in
order to turn off the Negotiation Progress Reporting. It also says that the
messages sent if this is on will be recognized as noise by Prodigy. 
Unfortunately, I have tried to add the ATW2 command using the software's 
modemstr.exe utility.  (modemstr.exe allows the user to add their own modem 
init strings), and the modem still get kicked off the service returning the
same noisy line message.

If anyone can help, please post here or E-Mail me direct at:

Wait, I bought 8 Zoom 14.4 External Fax Modems, had to send one back, but they
come with a 7 year warrenty.  My question is what are the problems with the
Zoom ?  The 2 reasons that I bought that brand over XYZ modem is that I hadn't
heard of any troubles with the Zooms.  And the cost of the Zoom was 100 bucks
less then PP's 14.4 modem.  As for supras I just stayed away from them after
the flood of problems and 4 month waiting lists.
Could someone enlighten me ?

I got a number of pinout match-up approaches for making a 8pin mini-DIN mac
serial port  to  25pin rs-232-c cable, and got the most rudimentary of them
working with a hayes compatible 1200baud modem.  But, I also have a Concord
Data Systems 224 2400 baud that I'd like to use, my problem being i got it
cheap, 2nd hand and haven't had a system to test it on with a known-to-work
configuration.  With the simple cable and the more obvious dipswitch settings
being tried, the SQ (signal quality) light stays on, which i thought (from
memories of having used a clone of this modem years ago) meant the carrier
over the phone was strong.  this is just when the terminal program is run, 
before the cpu has talked enough with the modem to dial, yet!  when i type
commands... returns to try to get the prompt of dialing mode, the TD (transmit
data) light flashes, but no promising echoing of that flash in any other lights
takes place.  Anyone have experience with these massive modems and their
4 banks of dip switches?  

i got the file from ftp at apple.com on the mac pinouts, and the update from
the author even, which lists some alternative configurations for more dumb
modems.  Anyone know which of these to try?  I suck at soldering.

I use since three months a Twincom 144/DF for my BBS and it's very nice modem.
I never try the fax features but a friend have many problems with the software

   This is interesting, but I refuse to even consider it for my arsenal of 
benchmarking trivia until I know a *lot* more than you've posted there!  For 
one thing, I don't trust throughput measurements on any file that takes less 
than ten minutes, and even then I use the *receiver's* CPS rate to eliminate 
the error introduced by transmit buffering.

   Try this: make a file one million bytes long, containing only spaces.  
Transmit it via V.42bis compression, and then transmit a version compressed 
with compress, zip, or even zoo.  I think you'll find that traditional 
compression doesn't do any worse than V.42bis, but it can do considerably 
better; unless there's a reason to send uncompressed data, you're almost 
always better off to send it compressed.  Hence when I discuss modem 
throughput I prefer to confine myself to the throughput attained without data 
compression and hope that it's indicative of throughput on precompressed 
files.

Get one of those de-soldering irons from Radio Shack with the bulb.
(No, I'm not talking about a seperate iron and bulb, RS makes an iron
with the bulb mounted on a steel tube that gets hot, melts the solder and
is sucked into the tube).  I bought mine several years ago, works like
a charm.  I can remove a 40 pin IC in 2-3 minutes.

ZMODEM overhead associated with 1k subpackets is about one half per cent.

The overhead associated with network protection varies with the
type of data transmitted.  With typical compressed files it is
many times the overhead from 1k subpackets.  MobyTurbo(Tm)
reduces this overhead considerably.

	I've dialed up their BBS and played around on it a bit ( one

	When I bought mine, I mentioned that I was intending to use it

I've not yet bothered with the FAX part of the L144, so I can't 
comment on it except to say that the supplied software appears capable 
and reasonably easy to use.

following is a list of questions I want to know:

    (1) How the V42bis modem works and where the best place to put it;
    (2) Where I can get/buy the V42bis modem, both software and hardware;
    (3) What compression ration I can get by using V42bis modem to transmit
        a binary file (or a text file);
    (4) How much the V42bis modem will cost; 

    Thank you for you help.
