- The Fine Art of Telesearching
- by Dragyn
- -----------------------------
-
- First off, i'm sure we all know what telesearching is, if not don't read this
- article. Telesearching can be done many ways, depending on what type of
- hardware and software that you have. Some telesearching should be done by hand,
- while, the majority of it can be done by computer. Now you might say, 'why do
- it by hand?' . Well to answer this question we must first take a look at some
- of the nifty things that the phone company has hidden in it's vast multitude of
- cables and switches. In almost every exchange, there are test numbers. What
- these numbers are for, you got me. But some are interesting at that. Up until
- recently, you could call one of the local test numbers and chat with other
- people that had called the same number. But, ma bell, didn't like us using her
- lines to chat freely when we could pay her to do the conferences for us. (There
- are other reasons that they turned them off also.) But now when you call the
- numbers, no one else could get through, (i.E. Busy signal) on a few of the
- numbers you can call and if you listen real closely, you can sometimes hear
- people chatting away, and mf tones zapping all around. (Now, I wonder what one
- could hear if they hooked an amplifier up to their phone...) Most of these
- numbers can be found in any exchange ending with these four numbers:
- 4010/4011/4012/4098/. But remember they aren't always there! Needless to say,
- there are many neat li ttle numbers that cannot be found by a computer
- telesearcher. Another type of strange numbers that you find are the ones that
- have strange tones on the other end. Like the ones that sound like sirens or
- just a steady blast. Again, I would like to know what purpose these numbers
- serve as well as you. I have a few ideas, but they aren't worth your time. The
- best part of an exchange to search by hand is from 9800-9999. In this range,
- you will generally find special operators and stuff as such. But remember, most
- pay phones' last digit can be anywhere from 9000-9999. So, if someone answers
- rather strangely, it's probably a pay phone.
-
- Now, back to computer telesearching. Having your computer do all of the
- dialing is a great help, you can go to sleep, and wake up with a nice list of
- numbers to check out in he morning. However, to make this list more accurate,
- one should be aware of a few things. First: telesearching generally works best
- if you have your own phone line that doesn't get a lot of calls. The more calls
- that your phone receives , the less accurate your list could be. And if you ask
- why, here's why. When your computer finishes dialing a number, it has to hang
- up the phone, and in doing so, the line becomes free to let calls in. If
- someone calls you at this point, your computer (if it's dialer isn't very smart)
- will start dialing at them, and you will lose numbers that could be computers.
- But depending on the type of modem that you own, this can be overcome. Modems
- like that apple-cat and the DC Hayes can detect to see if there is the dial
- tone, and if not, they can hang up, and pick the phone up a few seconds later to
- see if it got a tone again. (Enuf of this) I have found that the best time to
- wait for a carrier is about 18 seconds depending on how long it takes your
- exchange to connect to the other. Some exchanges are very slow and you have to
- compensate for this in your dialer. The 18 seconds allows the phone to ring 3
- times. (Most computers will answer after 1-2 rings, so the third is a safe ty
- one, unless you know of a computer that usually answers after more than th at,
- the 18 seconds is satisfactory. Now, where to look you might ask. Well, one
- thing to do is (if you have a particular company in mind) look up i t's phone
- number in the phone book and scan that exchange. What I have found as real
- handy, is the number/location list in the front of the phone book. Good places
- to search are downtown areas where there is a lot of businesses. I don't
- recommend scanning residential areas unless you are looking for something. Some
- people might say that telesearching is against the law. Well, for one thing,
- have you ever gotten a phone call from some computer that wanted to ask you some
- questions? Well, all these computers do all day long is dial numbers.
- Essentially, they are doing telesearching, however for something other than
- computers. If someone gives you trouble, tell them to phock off, since you
- aren't violating anyones' rights by calling them. They paid for that phone and
- you have as much right to call them as any jerk in the world. And I never heard
- of a law that said you couldn't call anyone in the middle of the night either.
-
- Now, what do you do that you have 69 zillion phone numbers? Well, de- pending
- on how interested you are, you could call every one to see if there is actually
- a computer there. But most of us aren't that dedicated if you have a whole mess
- of numbers. Now comes the part of identifying the numbers. You will probably
- find a lot of numbers that do nothing when you call them. This could be due to
- a lot of reasons. One could be that they have excellent security (boo). Or,
- you aren't in the right baud rate (i.e. 1200/300/110/ Etc . [ and some even
- run on a different ascii set.]). And there are the 'telex' type computers that
- are set up to receive data only. These carriers can usually be identified by
- typing ctrl-e (here-is msg). But remember, these systems record everything that
- you type! I could continue this article further, but somethings are best left
- unknown.
