-+ *
-+ * Extensively rewritten by Theodore Ts'o, 8/16/92 -- 9/14/92. Now
-+ * much more extensible to support other serial cards based on the
-+ * 16450/16550A UART's. Added support for the AST FourPort and the
-+ * Accent Async board.
-+ *
-+ * set_serial_info fixed to set the flags, custom divisor, and uart
-+ * type fields. Fix suggested by Michael K. Johnson 12/12/92.
-+ *
-+ * 11/95: TIOCMIWAIT, TIOCGICOUNT by Angelo Haritsis <ah@doc.ic.ac.uk>
-+ *
-+ * 03/96: Modularised by Angelo Haritsis <ah@doc.ic.ac.uk>
-+ *
-+ * rs_set_termios fixed to look also for changes of the input
-+ * flags INPCK, BRKINT, PARMRK, IGNPAR and IGNBRK.
-+ * Bernd Anhäupl 05/17/96.
-+ *
-+ * 1/97: Extended dumb serial ports are a config option now.
-+ * Saves 4k. Michael A. Griffith <grif@acm.org>
-+ *
-+ * 8/97: Fix bug in rs_set_termios with RTS
-+ * Stanislav V. Voronyi <stas@uanet.kharkov.ua>
-+ *
-+ * 3/98: Change the IRQ detection, use of probe_irq_o*(),
-+ * suppress TIOCSERGWILD and TIOCSERSWILD
-+ * Etienne Lorrain <etienne.lorrain@ibm.net>
-+ *
-+ * 4/98: Added changes to support the ARM architecture proposed by
-+ * Russell King
-+ *
-+ * 5/99: Updated to include support for the XR16C850 and ST16C654
-+ * uarts. Stuart MacDonald <stuartm@connecttech.com>
-+ *
-+ * 8/99: Generalized PCI support added. Theodore Ts'o
-+ *
-+ * 3/00: Rid circular buffer of redundant xmit_cnt. Fix a
-+ * few races on freeing buffers too.
-+ * Alan Modra <alan@linuxcare.com>
-+ *
-+ * 5/00: Support for the RSA-DV II/S card added.
-+ * Kiyokazu SUTO <suto@ks-and-ks.ne.jp>
-+ *
-+ * 6/00: Remove old-style timer, use timer_list
-+ * Andrew Morton <andrewm@uow.edu.au>
-+ *
-+ * 7/00: Support Timedia/Sunix/Exsys PCI cards
-+ *
-+ * 7/00: fix some returns on failure not using MOD_DEC_USE_COUNT.
-+ * Arnaldo Carvalho de Melo <acme@conectiva.com.br>
-+ *
-+ * 10/00: add in optional software flow control for serial console.
