Could you send me any example of that string? I think the conversion
you're doing does not really convert from hexadecimal format to Integer, for example:

Hexadecimal "FF" (= decimal 255)

Mid(Buffer,1,1)="F"
Asc(--previous--)=70
Str(--previous--)="70"
Val(--previous--)=70

--- With the other character:

...
Val(--previous--)=70

Then you use "&" operator so the final result is:

"7070" and then you assign it to a Integer so it is -7070-

???

I don't understand very well...
