  5 *
  6 *      This code is loosely based on the Linux serial driver, written by
  7 *      Linus Torvalds, Theodore T'so and others. The RISCom/8 card 
  8 *      programming info was obtained from various drivers for other OSes 
  9 *	(FreeBSD, ISC, etc), but no source code from those drivers were 
 10 *	directly included in this driver.
