+.SH DESCRIPTION
+.I Norio
+is a console file server which
+provides similar line editing and interrupt processing capabilities
+to those of rio to an un-multiplexed console.  It is compatable with
+vt100-style terminals (see
+.IR vt (1)).
+An integrated history
+mechanism is provided.
+.PP
+The file server serves
+.BR cons ,
+.BR consctl ,
+.BR snarf ,
+and
+.BR text .
+.B Consctl
+processes only
+.RB “ rawon ,”
+and 
+.RB “ rawoff ”
+messages.  The
+.B -l
+flag causes unrecognized messages such as
+.RB “ holdon ”
+to be silently ignored.
+Other files behave similarly to
+.IR rio .
+.PP
+Ornate keyboard editing is supported.  Every line entered is
+added to the history.  A cut/yank buffer is supported.
+The following key sequences are recognized.  Key sequences
+that require cursor positioning midline will erase text to the
+right of the cursor on Plan 9 console or in
+.IR rio .
+This is a consequence of not requiring overstrike to erase on
+the console.
