The input functions get it, the output functions (bpcharout,
bpcharsend, etc) don't. Which makes it kind of hard to print a raw
value if you don't know how long it's going to be. They used to, but
that was removed some time back. It's a security issue IIRC, since any
user could call raw_out(field, 2048) and get whatever was in the 2K of
data after that field.

Have a nice day,
