Mathematica: how to set the format of binary numbers in plotting?

I use BinaryReadList[filename, "Integer16"] to bring in an array of 
numbers. I then do a bunch of operations on these numbers and then try 
to plot them. They should be signed integers and interpreted in 2's 
complement but apparently they have been converted to unsigned binary as 
far as I can tell -- and the plots are horrible.

Can someone tell me how you can specify the interpretation (signed or 
unsigned) of numbers before they are used in ListPlot[] ? Thanks.
