## standard IO library

Basic support for standard-like IOs. This library can be used to perform IO on character oriented devices. Attachment to one device is based on redirection of an input and output function (see below).

Redirections can be changed at any time to use several devices simultaneously. However, remember that the input buffer is unique and should be flushed when the input device is changed.
