+ *
+ *      This code is loosely based on the Linux serial driver, written by
+ *      Linus Torvalds, Theodore T'so and others. The RISCom/8 card 
+ *      programming info was obtained from various drivers for other OSes 
+ *	(FreeBSD, ISC, etc), but no source code from those drivers were 
+ *	directly included in this drvier.
