Just a hunch...you might be overloading the line....Go around and add up the
load numbers for the phones...if you go over 100, that might explain the
problem.  I can't say for sure how bad it is...though I have the same problem
with two of my lines, and on one line I have over 200 for load number.  Dropped
it down by restricting myself to one modem per phone line.  Of course having
to get two more phone lines (and loaning one of the modems out) wasn't cheap.

I also had to chuck the answering machine.  My problem with line (audible)
noise went away....haven't noticed any disconnects when the other line rings
lately, but I'm less likely to be connected out when the other line rings
now.  I'm more inclined to be calling out on one of the newer lines.

The Trailblazer's PEP works at 9600bps max.
The Trailblazer Plus's PEP works at 18Kbps (now the WorldBlazer can do 28K).

Also, with newer versions of firmare (5.00 and newer), the TB+
can do V.42/V.42bis,MNP2,3,4,5.

   I believe that the general problem with Rockwell-based moems is not in the 
bugs and oddities of the chipsets themselves, but rather that everyone and his 
brother with a few bucks and no electronics experience can buy Rockwell chips 
and 'build' a modem around them.  The manufacturers that know how to build 
good modems - and who are willing to spend the money to make them that way - 
probably make decent Rockwell-based modems.  The no-name organizations in the 
Orient (and elsewhere, I suppose) that just slap a minimal modem together 
based on the examples in Rockwell's technical application notes make lousy 
quality modems.

   Perhaps someone with design experience with Rockwell chipsets (Ashok?  Are 
you still around?) can provide examples of specific problems and an idea of 
how relevant my theory is. <grin>

Anyone here on the net have some solid information on the latest ROM revision

This may have nothing to do with the Boca modem.  Windows 3.1 is a 
TERRIBLE environment for modems.  You MUST have a lot of horsepower
to run 14.4Kbps transfers and doing something else.  Is also very dependent
on what else you are running.  If you try to run something like Corel Draw
or Pagemaker along with hispeed transfers you are asking a lot from a
system.  You really need a fast 486 to accomplish this.

There is 1.28 out now.  With the newer ROM's most of the problems 
reported here have been corrected.  You have to consider that you
are getting a lot of techology for not a lot of money.  You get
what you pay for, if you want Perfection then spend about $500 more
and you'll be fine, otherwise the Boca modem is great for most 
people.  We successfully get around 1640-1650cps transfer all the time
and have many people call our CCS Tech Support BBS (410) 476-5098 all
the time getting comparable transfers from a Boca modem.

   No, they're just voltage converters to deal with RS-232's +/- 15V range.

   I've never seen a 16-bit dumb serial card.  The $400+ intelligent 
(coprocessed) multiserial cards come in 16-bit versions, and you can get 
serial I/O built into a super I/O cards that has a 16-bit interface for an IDE 
adapter, but UARTs are 8-bit devices and don't profit from 16-bit cards.

   To get the most data through with the least connect time, transfer it in 
compressed form (.ZIP or whatever).  Even a 14.4 kbps modem doesn't need 
higher than 19200 bps to get the best ZMODEM throughput possible on 
precompressed files.

   The 16550 should help your PC live with higher DTE rates, but that will 
onbly make a difference when sending uncompressed info such as text.

As far as I know, the v1.15M revision fixed most of the major problems (the
worst being difficulty maintaining a 14.4 connect)... the v1.21 revision is
supposed to fix some minor problems with inbound calls from some 2400-baud
modems, tweak some fax stuff, and change the defaults on a couple registers.
Nothing major, but since it's free, can't hurt to upgrade.  Don't send your
old ROM back right away, of course, try the new one for a week first.

Setting S38.5=1 is the same thing as setting S38=32.  On the display
you would have to convert the 32 (decimal) to 20 (hex).

My PPI had difficulties connecting to T3000's until I got the 1.15m ROM
upgrade.  Telebits are very good modems, but at their performance levels,
the "margin of error" for connections is pretty small.  I suspect that
a mixed-brand connection over the "noisy" lines you have would be destined
to fail most times.  (Two modems from the same manufacturer generally get
along better :)

If your 2500's are particularly early models, they might be a little buggy.
Telebit makes very good equipment, but nobody puts out a perfect modem on
the first release. ;)

The PEP hunt sequence (for the uninitiated, that strange mating-call a
Telebit does before it gets into normal carriers) does tend to cause a lot
of problems, particularly for those who run with only a 30-second wait.

I'll be nice and just say that using a Zoom certainly does not increase your
odds of getting a good connection. :)

Hi...I posted a message about a week ago in reference to 9600 baud
modems.  Now that I have been actively searching out the differences
between 9600 baud modems, I have become confused.  What is the
difference between 9600 and 14.4k baud modems? (besides the speed 8-) )
What is the true difference between V.32, V.32bis, V.42 and V.42bis.  Of
what I understand now, V.32 is just the 9600 standard, V.42bis is just
MNP levels 2-5 data compression to bring a 9600 up to 14.4k, and V.32bis
and V.42 more data compression and/or data correction.  If this
is a FAQ in another newsgroup, please send me email (or post) as to where
I can FTP the FAQ file or at least locate it.  Thanks.

I just started reading this news group, and have read all I can on this
particular subject here, but didn't seem to get an answer to my particular
questions, so I guess I have to ask anyway..

I just got a SupraFAXmodem v.32bis, my are the threads here vicious on
them, but so far I haven't had any problems at all, I do seem to have the
1.200-H revision roms.  Are these the most recent?? Anyway, I had to put
the com software down to 19,200 since the 8250/16450 uart just spits at
38,4 or 57,6.  Here is my question..

I have a generic 8 bit multi-io card, and the manual that came with it,
actually better than most I have seen, it actually gives details..  It
says to enable the second serial port I have to insert the following Ic's:
1488,1489,and 16450 (I assume this is the uart), I have seen the card, it
does have both serial ports installed, and the base seems to be setup the
same way.  In order to get the advantage of the 16550, can I just unplug
the 8250/16450 and plug in a 16550??  Do the other 2 chips (small like
drams) need to be replaced, if so with what??  Does it need to be a 16bit
card??  And finally where can I get a genuine National Semiconductor
16550AFN if all this is possible, for a decent price.  

Right now I am getting close to 1800 cps in procomm for windows, but I
wouldn't mind to see if I can get more, but also I would just like to run
at recommended rates, you know 57,6 for 14.4 compressed data, and all
that..  That is with Zmodem by the way.  

Funny, my supra connects to my university dial-in, but apparently I know
someone with a Intel 14.4/fax that can't connect above 9600 while I nailed
14.4 on my first try, I just am one of the lucky ones I guess..

Any info appreciated..

Hmm..  I'm *ALMOST* certain that this particular tbit I'm trying to connect
to had V.32..  (perhaps it wasn't a T1000 but another Telebit model?).. dunno..
If you're right, then it explains the my problem with the Telebit, but what
about the MultiTech?  I KNOW this one does V.32- I've connected to it before
with a Cardinal 9600- but the ZyXEL won't connect to it in V.32, only at
2400/MNP 4..  do I have to re-enable MNP5 or perhaps use a different &K
setting?
