Hook up a modem to the board, set p the modem to auto answer and have
the program wait for some string (hello world :-) and dump the data.
When done wait for another string to delete the data then a command to
hand up. If no hello then hang up (+++ ATH0).

I've simplified this a bit for explanation but it should be too hard
to do with the correct modem. You'll need an external modem, a phone
line, an RS232 cable and your stamp. I don't think you afraid to
program. :-) To use just dial in when ever you want issue the hello
and log the text data to a file. You could write an automated program
on your local PC to dial out and retrieve the data. I have other ideas
too.
