The place to ask is comp.dcom.telecom.  From what I hear:

(1) "security coding" is now common.  This restricts who can _dial_ from
your base unit, so that a person with a similar phone cannot drive up
outside your house and start making long distance calls on your line.
It does not affect reception of speech.

(2) Motorola now makes a cordless phone with a very simple kind of
speech scrambling.  Apart from that, all cellular telephone speech is
clear FM.

	This is (alas) not unheard-of.  The standard solutions are:
isolation amplifiers (these allow a floating measurement, so you
can disconnect common grounds); true differential amplification
(rejection of common-mode voltage is pretty good if you take care);
and preamplification (so that the silly microvolt signals
are decently large..like a volt or ten... before they get computerized).

	Fiber-optic IEEE-488 links are available, but 
are expensive (and only solve half the problem: you still have
the noise in two IEEE-488 boxes to contend with on the 'sensitive'
side of the application).

	You should try isolation transformers for the AC power
on one or two of your boxes, and analyze the ground configuration
for loops, and look for unintended capacitive and inductive coupling.
It might be possible to rewire the connections to the power lines
(and the data cables) to get your noise floor down to tolerable
levels.

  No suggestions - but if you can come up with such a device, you
  can probably make a lot of money with it.  (Assuming, of course,
  that the advertising agencies do not have you done away with :-) )
  Of course, you have to also have a mechanism for controlling

Organization: George Mason University, Fairfax Va.

Help! I need an rs-232 guru;

     I have a serial interfacing problem. I bought a receiver which has
a serial interface in the back for computer control. I want to be able
to control it from my HP-48 calculator, which has a serial interface.
The receiver has the following specs:

9600 baud, even parity, 7 data bits 1 start, 1 stop, half duplex, and
RTS/CTS hardware handshaking. Considered DCE. None of this setup is
changeable. The pinout is as follows:

1- Scan feedback; +5 volts = receiver unsquelched
2- Rx data
3- Tx data
4- DTE ready
5- Signal ground
6- DCE ready
7- RTS
8- CTS
9- Shield ground


The calculator can do 9600 baud, even parity, full duplex. The problem is,
it only has Tx  Rx  and ground.  It can do xon/xoff handshaking, but not
hardware handshaking. The calculator is DTE, and cannot be changed to
half duplex.

On the receiver, I have tried shorting DTE/DCE, and the receiver thinks
it's connected. Then, I tried shorting RTS/CTS and running the Tx/Rx 
from the calc straight through. This does not work. On the calculator,
when I try to send a command which requires a response, I get parity errors,
and a few characters of garbage. If I tell the calc to ignore parity errors,
I do not even get the expected number of characters back from the receiver.
I think the problem lies in the fact that the calculator does not do RTS/CTS,
and I cannot fake it out by shorting them, but I don't know enough about
hardware handshaking to be sure. It seems I need some sort of protocol
converter, which would talk to the calculator "normally" with no handshaking,
and pass the stuff back and forth to the receiver with RTS/CTS. Is this true,
and what would it cost?

I can connect the receiver to my pc, run procomm terminal software, and
type commands manually. But this ONLY will work if I tell procomm to use
RTS/CTS handshaking. If I short RTS/CTS on the receiver when connected to the
pc, this will not work. All of this leads me to believe that I cannot
get the calculator to talk to the receiver without RTS/CTS for real.

Is the kind of converter I'm talking about practical/necessary, or am I
just not doing something right? Please respond to me directly. Thank you
very much.

what  they do !).

The question is:

Is there a particular kind of hardware protocol/ and or modem

for noise  in the phone line.

I'm interested in taking a 2400 baud modem to India, where

 Any tips, pointers would be appreciated.

Organization: University of Georgia, Athens

There's one BIG possible problem:  The grounding is done differently.

As I understand it, European 220V service is like American 120V service,
in that one side of the line is at ground potential.  Right?

American 220V service is different.  Neither side of the line is grounded.
What you have is a 240-volt center-tapped transformer with the center
tap grounded.  120-volt service uses half of the transformer, with the
center tap as "neutral."  240-volt service uses both sides of the transformer.

It's overwhelmingly probable that the power supplies in your equipment
will expect "neutral" to be grounded, and will fry something if it isn't.

The best way to deal with the Amstrad PC is to replace its power supply with
an American one, or look inside for a 120v-vs-220v jumper or switch (many
computers have them).  Ditto the low-powered audio equipment.  The huge
audio power amplifier will be more difficult; can you replace its
power transformer with one that has a 120v primary?
