I just recently purcahsed a PPI 14400FXSA v.32bis from a fellow on the
net. So far it has been very good and I haven't had any problems with it
except that it refuses to connect at 1200 to a local BBS (they have some
very old USR modems). Netcom uses Telebit T-3000s and I have had no
problems connecting to those. 

I haven't tried the FAX part because it didn't come with Macintosh fax
software, but it came with QuickLink II for the IBM PCs. 

The only problem with my modem would be the price (If I were to have
bought it mail order). The lowest price I've heard is $390+ shipping.

Also, I called Pratical Peripherals tech support line this morning and
asked if I could get upgraded to 1.12c ROMs. They mailed them out, free
of charge.

I've heard bad things about Supras and Zooms both (which is why I'm
glad I got the modem I did). You may have to wait a while before they
get all the bugs out and if you want to get a high speed modem NOW,
you best bite the bullet and get one from a company like Prometheus,
Pratical Peripherals, Multitech (A friend of mine has one of these and
he loves it!), or Hayes. You may pay a little more, but these companies
have a more reliable chipset in them.

Greetings!

I've got a user who has a Twincom 14.4 w/Fax modem (v.32bis).  When attempting
to connect to a USR Dual Standard, he gets the CONNECT 14400 message followed
immediately by garbage for roughly 1 minute until the modem disconnects.

When attempting to connect to a Telebit WorldBlazer, he has no problem.

Obvious solution?

Any and all help will be most appreciated.

Thanks,
Derrick Cole

P.S. Both the USR and the Telebit are rack mounts with the latest ROMs
     connected to an Annex IIe at 38400 fixed with hardware flow control.

P.P.S. I don't know anything about the Twincom other than what's above.

I have finally decided to buy a new modem, and since I want to be able to use
both HST and v32bis I have come to the conclusion that I should buy a USR 
Dual Standard. However a few seconds of looking through ads left me with
the impression that USR uses one name for a number of different options.
Could someone please tell me what a HST,v32bis/v42bis 57600bps-capable USR

        I read in some ZyXEL information I have that their 1496S has some
cellular modes as well (!).  Apparently the at&N command supports a 4800
bps cellular mode as well.  I'm not sure what it is exactly but I remember
seeing more aobut ZyXELs an cellular before.  Maybe it's v.32 4800bps (?)

   Yeah, I knew that - I was just trying to point out a similarity /

lines in this sort of discussion.  

   What did the half-duplex modems do with the DTR/DSR line set?  The

What is NEUTRAL?  Phone lines have a Tip lead and a Ring lead.  Ring is
negative with respect to Tip.  The line has 48 vdc on it when idle.

What is this "voltage across neutral" that "the vast majority of home
lines" have?

That date was first postponed to "the first week in August", then
further delayed with one week, as Supra is adding a new feature to the
ROM. Personally I rather wait one more week for a good ROM than get a
buggy one earlier. The modem was released too early, but now Supra is
making up for the mistake by not releasing the updates too fast.

Your problems with high speed over Long Distance lines might well be
the lines. If the line quality is poor, the modem can't use high
speeds.

I haven't have a problem setting my comm program, and other ones I've used,
to a higher baud (e.g., 19,200, 38,400, or 57,600).  If you're calling

There is a device which plugs into a power outlet and lets you add jacks

Dallas is, IMHO, very willing to please their customers.  They are
'new' relative to the market, but looking back, many now-reputable
modem manufacturers were once 'new' relative to the market...

A friend of mine purchased a DallasFax 9600 v.32/v.42 modem and was
quite satisfied with it.  However, then DallasFax put out their 14.4
and he wanted one of those instead.  He called up DallasFax hoping he
could 'upgrade' for a minimal cost, and instead they gave him a direct
swap!  I was amazed.

Some configurations may suffer minor reductions in throughput when
enabling v.42bis as compared to a LAP-M only connection.  I'm not
sure whether it is because of some changes in timing or a lack of
compute power in the modem, but this was noticeable and reproducible
on Telebit T2500's.  This was on a cslip line without VJ compression.
I imagine that some other modems may also experience this.

However the V.42bis helps alot with SMTP and NNTP, so I leave it on.

It may be that the COM drivers have not been installed completely yet or
something similar. The OS/2 boot process happens in the background if
you have a STARTUP.CMD 	file.

Correction: Some Telebit models *used* to have a secondary interface.
I have a T2500, and I too was intrigued by the wiring diagram in the
back of the manual for connecting a secondary DTE.  So I went out and
got three RS-232 connectors and some wire, and made a T-connector for
my T2500 to split the modem connector out into primary and secondary
DTEs.  Well, I connected it and it didn't work.  Checked the
connections with a VOM, and everything was as described in the manual.
So I called Telebit tech support.  Apparently this feature had been
removed from the "consumer"-grade modems -- since no one was using it
and it was a way to trim a bit off the cost of making the modem -- but
no one bothered to tell the folks who wrote the documentation.

Needless to say, I was a bit peeved after spending $10 on serial
connectors to discover that it had no chance of working, but I guess I
should have expected that.  The whole idea is a bit too good to be
true.

On a somewhat related note: Who will be the first modem maker to
implement a TCP/IP interface for their modems?  Design it like the FTP
interface, with one port for data and one port for commands, and there
will be no problems with in-band control sequences...
