Dowty *had* to tell you that. Per FCC regs, *you* cannot repair their 
modem. Only one of the manufacturers authorized service techs can.

The same goes for *anything* that connects to a phone line. Also,
if *you* repair it and due to a goof it causes a problem with the
phone system, the phone company can go after *you*. I doubt you'd
cause any problems, but the law is intended to prevent Joe Hacker
from attaching a homebuilt device to the phone system.

This is not any different from the situation wit radio transmitters.
If you aren't licensed or at least a manufacters service tech, you
*cannot* legally work on it.

I finally received my modem from BFJ on the 22nd of July. I ordered 
it about 3 months earlier. They told me it would take 2 months.
	Though the price was good ($289 plus shipping), they seemed 
irresponsible (in my opinion). I was on a waiting list for all of 
that time, and when I called back after 2 months, they said I was 
still at the  bottom. After 3 months, I called again and they said, 
"oh, we are just filling orders for those on the waiting list that 
call back." I was very upset --- they weren't even using that list!!!
They must have sensed this, because they shipped a week later.
	Just before they shipped, they told me that they couldn't get 
my Mac Hardware handshaking cable, which they assured me wasn't no 
problem to get 3 months earlier. But when I got the bill, they had 
charged me for the cable anyway!  When I called back, they assured me 
that they "probably certainly" had reversed the charge on my 
mastercard for the cost of the cable, but I have seen no evidence of 
this as of yet.

		The price is right, but the service isn't worth the cost.

I'm having an odd problem with a WorldBlazer.  It works fine as dial-in,
dial-out, uucp, at all kinds of baud rates and modulations.  But every
once in a while (approx every other day) it simply hangs.  If you dial
in, the modem never answers.  From the host side you can tip to it, but
it does not respond to AT commands or dials.  The only thing that clears
things is a power cycle.

Frequency of occurance is definately related to frequency of use.

Any ideas?

Now I have a BIG problem ...
The V5.00 roms have been distributed here in Germany as an *official*
version, obviously some misunderstanding between ZyXEL and the german
distributors.
A lot of people already are using this version and there is general
excitement about the quality of this update! All bugs of previous
versions (that I'm aware of) have been fixed, 16.800 bps transmission
works flawlessly, and the voice mail capabilities are fantastic.
V 5.00 definitely is the best piece of "beta code" ZyXEL ever sent out
to the world... :-)
In fact, it out performes *all* of the previous production releases by
far.
Now, if this is just beta, what am I supposed to do with my new eproms :-) ?
Change back to V 4.09, which was installed before the upgrade? Nah, you
can't be serious...

My congratulations again to the ZyXEL engineers for producing this
fantastic release - what other modems are supported in such a way?
I started with buying a modem with V.32bis and FAX - now I have a
modem with additionally 16800 bps, voice mail, a lot of new features... 
just for the cost of two new eproms (about 15$)! 

[ no connection to ZyXEL, just a very satisfied customer ]

Out of casual interest in learning about the REAL RS232 Standard I
called EIA to order the standard document and was shocked to learn
that the standards documents were like $60 a piece.  
At the time I was interested in the correct way to hook RS242 to RS442
and found that was another $60 document.  I noticed you quoted from
the standard in this note, and was wondering if any of the standards
documents were inexpensively available (like anon. ftp!), and if not
what is the rationale?  I can understand recovering costs, but this 
has the negative side affect of limiting the availability of first
hand knowledge of the standard.

Have fun with this new functionality - BUT:

Note that I subscribe to the CLID service - Southern Bell charges an
extra $6 a month to send this information with each call and also
charges a $12 start-up fee if you don't get the service at the same
time you are ordering service to be connected.  Without subscribing to
this service, I would not be able to see this information because it
would not be transmitted to me.  Please don't send me mail complaining
that it doesn't work for you.
   Note that this feature is not documented in any literature Supra
has provided to me and may not be fully debugged yet, all I have
noticed is that it worked twice with the same caller earlier this
evening/morning.  Hopefully this feature is more robust than dial tone
and busy signal detection which don't always work for me, but also
aren't really missed.

This is almost exactly what I did. I cancelled my ATI in March I think.
I then cancelled my modem in April. Well, out comes Teddy Boys letter
and I start wondering .... Did they really cancel my order? Why did I
get the letter? I called GW and of course I couldn't get through to
Customer Disservice as usual, so I left a message with the operator
to make sure my modem order was cancelled. The next day they left a 
message on my answering machine that they were now cancelling my TWO
modem orders.
I NEVER ordered 2. Well to make matters worse, guess what FED EX tried
to deliver to me a couple of weeks ago. The modem and the ATI card. What a 
bunch of schmucks over there. I'm really beginninng to wonder how they can 
stay in business with such a screwed up organization. I am sorry I ever
bought my computer from them. (I already talked about my monitor problems
before). Next time I will buy a system locally. I think it's worth the
slight extra cost.

[Rest of text deleted]

Good luck to anyone who has to deal with that bunch of bozos!

  On a Sun3 that I use, I managed to get ~1600 cps receive and ~950 cps

get cut down by flow control problems between the worldblazer and terminal

ports (max out at 19200 bps transmit, 9600 bps receive, etc).  I simply
lacked the ponies to do much better.

  People who like fast modems beware...  I'm fairly unimpressed with the
serial ports and drivers people stick on UNIX workstations.

X requires a TCP/IP connection, which means you'll need to run PPP or
SLIP between the UNIX system and your PC.  Free and commercially-
supported implementations of both protocols are available for most
UNIX systems - ask on comp.protocols.ppp for pointers, or write to
marketing@morningstar.com for info on our product.  I've heard that
there are some nice X-over-SLIP (and maybe X-over-PPP) packages for
DOS PCs, but I can't give you any recommendations since I'm not a DOS
kinda guy.

Alternatively, there may be an X-over-XRemote implementation for PCs,
which would talk to a similar driver on a UNIX system.  This wouldn't
require (nor offer the advantages of) a real TCP/IP connection between
the PC and the UNIX system.

Before I called Telebit to bitch about the uucp spoofing problem, I
must have spent an hour with the domain operator Uutrying back and
forth and writing down numbers - trying every imaginable case and
setup. I was ready for anything.  However, the minute I mentioned what
I was calling about, they just took my address, and FedEx brought the
EPROM's a few weeks later.  I had gotten all worked up for nothing!

Honestly, though, it should be kept in mind that with the uucp bug, the
WB was really a defective product by default.  Telebit is aware of
this.  While it would be better if the product had been fully
functional at the start,  some companies sell patently defective stuff
and then never support it at all.  Telebit is MUCH better than that at
least!
