w810 ticker message via bluetooth using bash

Assuming bluetooth is setup already and the Sony-Ericcson W810i is bound to rfcomm0. XX:XX:XX:XX:XX:XX is set to the baddr of the phone. Takes a few seconds for the rfcomm to go connected. The sleep command sets how long the ticker will display for, the rfcomm closes when the script exits. #===========cut here ===============================
