I didn't really think about text messaging - pressing buttons multiple times
to enter code words could get tricky.

I was thinking more along the lines of using the RCX's builtin beep codes -
though I just realized that wouldn't be very practical or effecient. If
this is all for communicating to the computer, dialing the modem and getting
a DSP (or whatever chip they use to create the DTMF tones) chip to interface
with it would probably be the easiest.
