 iolib.termios - an iolib (http://common-lisp.net/project/iolib)

+extension for RS-422/485/232 (aka serial) interfaces - i.e. termios (3)
 api common lisp wrappers.  It is still proof of concept now, and
 currently there is no documentation, except docstrings.

 Some notes:

+I start wrote this stuff in order to make my code for communication
+with some embedded devices wih via RS-422/485 interface not too
+implementation depended (I using some sbcl wrappers from sb-posix:
+http://paste.lisp.org/display/87952).  In other words main purpose of
+the iolib.termios is more like to provide a portable way to talk with
+modem from lisp, than to cover all termios features.
 Each instance of the `dual-channel-tty-gray-stream' store original
 termios settings (baud rates, control characters values etc.) and
 call `close' on such stream will restore this settings.
