And I don't understand why you keep assuming that I wanted to say the IMEI MUST
be CONTINUOUSLY transmitted throughout a transmission. That isn't what I wanted
to say, and I thought I explained that clearly enough.

So again, how do you make a call without initiating it? And IF the IMEI IS
necessary to initiate a call, how can it be considered "optional"?

RB>> ;-))) Who told you that one? Sorry, I know better.

MV> As I said, I saw it demonstated. Not on television, in real life.
MV> Standard data cable.

COM to what? Cell phones don't have COM inputs, at least no cell phones I've
ever seen. That's why you need a COM to interface cable for the pertinanet
phone. Aside from which, what are you calling a "standard data cable" anyway?
That would be COM to COM, maybe a null modem cable or something like that. But
where's the cell phone with that kind of an interface?

Possibly. What phone was it exactly? Make, model? I played with one of the
older Nokias, I think a 3210.

As I've already explained several times, I comment on what I quote. Your
comment, on which I based my above remark, was:

MV> Simple is in the eye of the beholder. Once you know how to do it, it
MV> ius simple.

To which I replied:

RB> Interestingly enough, I've found that's not the case.

And included the example you quote above. Read what I write in context, not as
isolated snippits, and things will be much more understandable.

As for  why I wanted to change the IMEI, quite simple: I wanted to see how it
was done and if I could do it. I like to learn, like with the supervisor
passwords.

RB>> At any rate, there's a website that deals with this subject, and even
RB>> free software to read out the passwords...

MV> Now is that for the thinkpad, or for the cell phone?

Was the above about supervisor passwords for the Thinkpad or about the cell
phone IMEIs? I can't recall even mentioning passwords for cell phones.

Sorry if I sound gruff, Michiel, but I've had quite a workout with the Bandit
today and I'm dead tired and I think your question answers itself if you just
read what I wrote.

RB>> Knowing how in theory is nice, but without a bit of practice and

MV> Very true. I already found that out 40 years ago. I could not make

Oh, I never claimed to _understand_ how the circuit works or how the program
reads out the supervisor password. But I can follow a simple schematic without
much difficulty (accent on _simple_), which some people apparently find quite
difficult.

The thing that astounded me was that my friend (who had the circuit boards for
the powered interface etched) couldn't use the device properly even after I
made it up (with components) and checked it for him. I have no idea what went
wrong on his side, but it worked fine for me.

Cheers, Bob
