The modem is turned on and the pic configures it to disable command ds2775, change to return numeric responses and turn off the volume of the modem speaker. The pic is coded in mikroC and my problem is at the level of the connexion between DS it’s a max without capacitors and the SUB-D port the circuit will be able to connect to a pc.

Finally I changed the sub-d port and now it works however don’t know if in reality it will Do you know if there is an off-the-shelf version of a picture sending auto dialer??? A passive infrared sensor PIR is waiting for a person to enter a room.


Your invention is great but it helps if you have the technical smarts to do it. Users browsing this forum: Mon Nov 09, When it is detected the pic dials a fixed phone number and the user will receive the alert.

Do they make a digial sensor that will work or is there a attachment that will change analog to digital. No registered users and 9 guests. I would love to find a device that would do the same thing and send me a pic.

The advantage of modems is that you can interact with the phone line for making calls.
