data processing using excel

Hi to all,
First of all I'm new here so forgive me if I'm not clear enough.

I want to receive and display data in a convenient and clear interface so that I can detect changes in a repeated sequence.
The data consists serial hexadecimal characters which are transmitted to a usb port constantly.
every string consists 4 Hexadecimal characters. ( 08c2 08f2 0911 0911 ...)
for displaying the data in the first place I'm using a terminal software "realterm" (there's no terminal software in windows 7).

There's an option in the software to capture the incoming data and save it to a txt file. As you can see in the image the display
in the software can consist spaces which is good for my purposes, but when captured to the txt file the whole data is one big string with
no spaces, therefor trying to copy the txt file to excel also results in a one long string. I managed in other data types to use the text import wizard successfully. In order to be able in excel to arrange the data in columns I programmed the transmitted data so that every after 8 strings been transmitted there's an "FF" transmitted.

In the realterm software there's an explanation of how to control the software via excel but I didn't understand
how to do that:

eventually what I'm seeking is to see (if possible) at real time in excel the data in a convenient display -
more or less that I can scroll the data and find easily changes in the sequence.

Thanks,
Amitai
