I know i will be called an old dinosaur when i say this but - Ladies please could you be careful with the 'bad' language?I do let Alex read some of the posts on here - well those that make him laugh or of any interest to an 11year old!

Please dont think i'm not a good sport - there is a place for bad language - i do post some jokes with bad language in - but as the saying goes 'there is a time and a place'....😱Bev
A terrific book to read is 'Approaching Zero' which is about the early days of hacking. People used to go 'dumpster diving' - getting old telephone engineers manuals out of skips so that they could hack into phone systems. One hacker was called 'Captain Crunch'. He discovered that a free whistle given away with Captain Crunch cereal had the exact tone that, when blown three times doen a public telephone receiver, gave you free calls! It was normally only known to engineers so they could test lines!
This was in America where local calls were free. 2600 Hz was the frequency and what you did was to dial a local number which turned the charge metering off. The hacker would blow the whistle which then told the exchange to route you to the part of the exchange which dealt with long distance calls.
For those who want to try it now don't bother - there are now filters in the exchanges to stop it.
