VBScript

Hi Guys,
I have been struggling with the below VBS from past few days. Its basically used for checking the dial up connectivity through hyperterminal. It was working fine on WIN XP but now i have migrated to WIN7 (x64) and it has stopped working.
I would like to request you guys to either advice me for the break fix to run it on WIN7(x64) or any better script wich serves the same purpose.
