If this is serial protocol then just do a serin with the
Stamp 2. See the docs for that, or

Serin SI,N2400,B0                       'SI=port  B0 = input
character (might want a timeout value)

If it is pulse width modulated, then you can try Don Roy's
code (I have a copy on my site at:
http://204.233.101.40/robots/irremote.txt ) or at least look
at it to see how he is handling inbound Sony code.
