does anyone have the c code to program a picf458 to pulse dial a phone number or two?

I got locked in a building that was under construction and the phone had a lock on its dial. I used the hookswitch to call for help to get out.

In some countries (eg. New Zealand) they are more logical. Zero is one pulse, one is two pulses, etc.kchriste said:There are different standards in different countries so we need to know where you are located.
It should be pretty simple to write this code yourself. In North America the pulses are sent at apx 10 pulses per second with a half second pause between each digit (this is my best guess). One pulse for a 1, 2 for a 2, etc with the exception of zero which is done with 10 pulses.

I am one of the few remaining Canadians with "pulse dialing" on my phone line. I don't pay the DTMF rip-off fee to the phone company, month after month and year after year. After dialing the number on an electronic phone I switch it so I can control things like banking by DTMF.

I don't think we have such a stupid thing in the UK, anyway you might be able to save money by switching to a different company.audioguru said:I don't pay the DTMF rip-off fee to the phone company, month after month and year after year.
You had better emigrate. DTMF has always been free here - because it reduces register time.audioguru said:When DTMF was invented, BELL was the only phone company and they charged an extra fee for it. Then other phone companies were allowed to compete with BELL and they all charged extra for DTMF.
They recently all got together to try and force the few remaining people (like me) who had rotary dial service to go on DTMF because we were actually costing them more than DTMF (the registers were used for a longer amount of time with slow rotary dialing than with quick DTMF) but we launched a class-action-lawsuit and prevented it.
There were various tricks they used here too.audioguru said:Whem I was a kid we used to make free calls from pay phones by grounding the mouthpiece with a paperclip.
