Your problem about the 'R'-key for your PBX sounds like it uses the E-line  
(earth) for signaling between the phone an the exchange. As this is  
somewhat outmoded, ZyXEL has not provided for a old style four wire phone  
line. Thus it internally only switches the common two lines used for dial  
and voice signal. You will need to solder your own circuit to route the  
earth line around the Zyxel or replace your private exchange with a newer  
model, that uses only two wire lines. If I'm right there is also no way  
the modem could send a 'R'-signal as it doesn't have the additional  
wiring.

As I'm just guessing try to get more facts about the wiring of your phone  
and exchange before you spend time and money to fix it, although I guess  
I'm very close to the actual problem.

Quick Summary:  Does anyone know what the DIP switches on an old Hayes
		1200 baud modem control?

The story:

I recently adopted an old Hayes 1200 baud modem that was headed for 
the garbage bin.  Upon hooking it up, it acted as though it were
set for dedicated use -- it seemed to immediately try to send bits 
down the line.

I opened up the case, and tucked away in the back are eight DIP switches.
However, I have no manual for this ancient beast.  Does anyone have
a manual or know what the DIP switches are for?

Does the modem actually sends out noise to the caller?
Does it have the compability to distinguish between a fax call and a
modem data call?

Also, does the PC version of the Scout Plus do the same thing?  If
not, how can I write a TSR for it?

It will.

A VLSI chip can mean two things : That the chip you have is some Very Large 
Scale Intergration job, which holds, for example, the COM port, LPT port and 
drice con's. In which case you can't do nothing about the chip. You'll have 
to buy yourself an extra serial card with socketed 16450's that you can 
replace or buy one that has the 16550 to start with (then there's no need to 
replace anything). That's the most likely thing.... 
It can also mean the computer has the VLSI chipset on the motherboard, that 
has nothing whatsoever to do with your COM port. 

So basically : Just open the machine. Check if the COM port is in some VLSI 
chip (very large scale.....) (Which is a small (usually about less than 1*1 
inch), multi-legged device, usually SMD (surface mount, those damn' small 
legs that are soldered to the component side)) or a real 16450 (AKA 86450, 
AKA 16?450) or 8250 (even older than the 16450). It's easy to find : a 40-
pin DIL (Dual In Line) chip, with legs that are real pins that point down... 
(about 0.6*4 inch) If you find this, check if it's in a socket so you can 
just pull it out, or if it's soldered to the motherboard. 

If it's a VLSI, you can't do nothing. Just buy an extra serial card and 
either set it as the next COM port(s) or disable the ports on your 
motherboard. If it's a soldered 16450, then again you have to get an extra 
card (Well, if you REALLY REALLY have to, it is possible to desolder... I 
wouldn;t advise that, however, and let someone experienced do it...) If it's 
a socketed 16450, you're in luck : Get yourself a 16550 AFN (NOT the A, it's 
no good. You really need the AFN), pull out the 16450 (carefully !) and push 
the 16550 AFN in (again : carefully), the same way the 16450 was in. (check 
the indenture or spot on one of the short sides).

Right.  What I really meant was that not only is the USR 16.8K "unique",
but there aren't a whole lot of them out there compared with other "odd
ducks" like Telebit PEP, etc.  Or maybe I'm wrong, maybe everyone that

I was having some problems connecting with some local boards at 2400 using my
ext. SFM v. 32bis.  Like you I got a connect message and then a disconnect.
This seems to be resolved by setting AT\N0 (Sets operating mode to normal).
However, I think this means you lose data compression and error correction
for any connections made under this setting.

The latest round of boards are basically E+ machines with a few minor
changes:

1) a 12 MHz CPU rather than 16MHz running at 20..
2) Custom labelled DSP chips with internal RAM to avoid the daughter board.

That's the larger RAM board...

There may also be a checksum/serial number/model number programmed into
the EEPROM where the profiles are stored. (this is a 512 byte EEPROM of
which there are 4 profiles of 56 bytes each and some phone numbers and
passwords... lots of spare room)

Actually, I think the speed is handled by two jumpers (each of which

Manual? Mine is version 2.0, and doesn't cover voice mode AT ALL!

Where can I get either a newer manual, or a postscript/ascii version
of the latest manual.

It's not going to kill ZyXEL to have this available, as the only people

Thre is the misconception that the 16550A & 16550AFN are two diferent
UARTS. They are not! In reality, they are the same. Both function the
same way, i.e., with FIFO buffer. The 16550A is the soft designation.
The 16550AFN is the hard(ware) designation.

But there is one buggy UART. It is the 16550. This UART is with the FIFO
damaged. So, 16550 is bad, but 16550A is good!

Your new modem is probably connecting with MNP error correction; this
sends and recieves data in blocks which results in the jerky screens you
see. You can 'fix' the problem by disabling error correction, if you like
(I do find the jerky behaviour at 2400 baud annoying, on good lines I
prefer to drop the error correction and take my chances...).

He likely was correct, many systems don't use "real" UARTS, they use
a VLSI chip that is programmed to emulate the uarts and other parts.

No, it's an "Internationally recognized standard for serial automatic call

In other words, an alternate to the Hayes "AT" command set.  Probably used
mainly for/with IBM's, since they have to do everything different anyway (-:

some guy writes a FAQ dedicated to answering this question and this question
alone.

        I almost never ask questions on the net.  Why?  Because every
time I have a question, the first thing I do is wait.  I read all the
old postings.  Then I read the FAQ.  Then I wait a week, reading all the
traffic.  I also work on the problem myself and think about it.  98% of
the time I discover the answer myself without posting.

        Does this process drive me crazy?  Obviously.  But worse is turning
myself inside out like a pretzel to reduce net noise, then watching
net.idiots fire off the first stupid question that plops in their heads
Makes me feel like a fool.  Maybe I should just start posting away the
minute any old question comes to me.  Hey, guys, how do I find out what
version roms I have?

There was no price increase.  $149 is the original price, however Telebit
was running a special of $99 until 31 Dec 92.
