[riot-devel] STDIO only accepting ASCII due to signed char?

I'm currently trying to write an ROP chain as an example on how the
Jiminy-board might be abused. During that research I noticed that RIOT

chars. Therefore RIOTs behaviour becomes, at least in my opinion, kind
of undefined when sending e.g. 0xff.
