Reading a live data stream?

Hi all,

I have a 6 channel live data steam coming in via com1 and I was wondering how to access it. I've been able to read from a ascii file, but not a live data stream yet. Anyone have some suggestions? format as follows.

0.000 0.025 0.758 0.064 -1.003 0.400

Thanks for your time

-Cheers
