Thank you.

I think I will now be able to pull the project off when I get time, and a couple more $$'s

- Picking the phone up when it rings will be ok (check for speaker high - short out the 'green' button.)

- Putting the phone down will be ok (short out the 'end' button).

- Sending the data *may* be ok (replace the mic with fly leads), however, the mics are miniscule, so theres a big chance of me breaking it!


The only problem I see is the data itself. You mentioned using a low baud rate (outputting the data as text?). Would this be better than devising a 'morse code' style system, sending different length pulses - perhaps a short one to mean '1', and a long one to be a 'break'??

Thanks for your help
