We use "vsprintf" function defined in libc.a (newlib) and we need
need also "isatty" function that is called from vsprintf().
This function is defined in various library (i.e. libads.a, libnosys.a,
libyk.a,..). Which of them is correct one?
Is there anywhere any document about these libraries and
differences between them?


Thanks
