	  If you say Y here and create a character special file /dev/rtc with
	  major number 10 and minor number 135 using mknod ("man mknod"), you
	  will get access to the real time clock (or hardware clock) built
	  into your computer.

	  Every PC has such a clock built in. It can be used to generate
	  signals from as low as 1Hz up to 8192Hz, and can also be used
	  as a 24 hour alarm. It reports status information via the file
	  /proc/driver/rtc and its behaviour is set by various ioctls on
	  /dev/rtc.

	  If you run Linux on a multiprocessor machine and said Y to
	  "Symmetric Multi Processing" above, you should say Y here to read
	  and set the RTC in an SMP compatible fashion.

	  If you think you have a use for such a device (such as periodic data
	  sampling), then say Y here, and read <file:Documentation/rtc.txt>

	---help---
	  The ACP modem (Mwave) for Linux is a WinModem. It is composed of a
	  kernel driver and a user level application. Together these components
	  support direct attachment to public switched telephone networks (PSTNs)
	  and support selected world wide countries.

	  This version of the ACP Modem driver supports the IBM Thinkpad 600E,
	  600, and 770 that include on board ACP modem hardware.

	  The modem also supports the standard communications port interface
	  (ttySx) and is compatible with the Hayes AT Command Set.

	  The user level application needed to use this driver can be found at
	  the IBM Linux Technology Center (LTC) web site:
	  <http://www.ibm.com/linux/ltc/>.
