Read the values in hexadecimal and not in ASCII

[joliverr]

Hi!

When I try to read a value between 32 DEC and 126 DEC , the readed value shows in ASCII.
But when I read a value between 00 DEC and 127 DEC , or between 127 DEC and 255 DEC, the readed value shows in Hexadecimal.

I want to read all the values in hexadecimal.
