Fix unwanted sign-extention when converting byte -> int

byte(255) converts to int(-1). This is not what we want, we want
int(255), in other words unsigned conversion.

This bug is causing premature EOF when read() is called, because when a
byte(255) is returned, it gets sign-extend to int(-1), causing the
caller to think EOF is reached.
