I have a file that has 2 bytes of binary indicator values in every row that has to be stripped off.

I tried sed, awk, cut but none of them work (though they work in vi mode):

sed 's/^.,2//' file.dat
awk 'print substr($0,3)' file
cut -c3- file

Example:

<84>^cColumn1,Column2
x^CColumn1,Column2
v^CColumn1,Column2
<81>^CColumn1,Column2

Desired Output:

Column1,Column2
Column1,Column2
Column1,Column2
Column1,Column2

Using cut:

cut -b 3- infile

This will cut the first 2 bytes from each line or print from 3^rd byte to end of line.
