cellular phones?

Archiver

Does anyone out there have any ideas/suggestions for interfacing a stamp with a
cellular phone? I thought it could be possible to adapt the
speaker/microphone/redial button, automate the keypad in response to sensors run
through the stamp etc.

Hi there, I have been working on a project that uses Cellular & Paging systems
for control... it is a car alarm using the BS2 as it's CPU. The alarm already
sent out a paging signal with a radio transmitter but if you are out of range
the idea
is to call the user's cell phone and make a series of beep tones. The first try
was modification of a damaged Nokia 232 analog handset by using it's Voicemail
button to call a pre-programmed number instead of having to use all of the
number
keys. So 1 I/O pin can be used to place the call and the person who answers just
hangs up when they want to. Audio is inserted using the mic connections. This
works just fine and is really easy to connect. The phone was activated on a
pre-paid
card system...

Another approach is to talk to the phone's CPU directly. Using a Motorola PCMCIA
Cellular Modem it can dial the number
and send it to the phone. So this is possible, just finding the protocol
information may be difficult.
