i'm trying to receive some serial data on my pic 16f688 but it doesn't receive anything (sending data works perfectly). i'm want to blink a led on the pic on command.

I use this code to send the data from my basic stamp 2:

SEROUT S_out, 396, ["blink"]

and i use this code to receive on my pic:

SerIn2 S_in,396,[WAIT("k")]
gosub blink

what can it be?
