OVERVIEW

	This is a very fast and simple explanation of using these tools for the

	Dallas Semi 1921 iButton.  These instructions may help you run other

	such ibutton devices.

COMPILE AND INSTALL

	./configure 

	make install

USAGE

	The fisrt thing you will want to do is search your serial port for all

	of the devices on the serial bus.  First start by setting your

	MLAN_DEVICE environment variable so that the serial port is known:

		(t)csh:

		setenv MLAN_DEVICE /dev/tty00

		(ba)sh:

		MLAN_DEVICE=/dev/tty00

		export MLAN_DEVICE

		Note: For Linux OSes, your first serial port may be /dev/ttyS0

		Note: If you receive permission denied errors, please see your

			system administrator for appropriate permissions assignment

			for your user.

	This should result in output similar to:

		$ ./search

		Serial[0]:  xxxxxxxxxxxxxxxx -- DS1921 Thermochron

		Serial[1]:  xxxxxxxxxxxxxxxx -- DS9097u 1-wire to RS232 converter

		$

		Note: "xxxxxxxxxxxxxxxx" will be replaced by your serial numbers

	With these serial numbers and your serial port, you are all ready to

	go.  First you must set up your ibutton to have a mission.  A mission

	is simply telling the ibutton what to

APPS

	search

		Takes no required parameters but does require that the MLAN_DEVICE

		environment variable points to the serial device

		(default: /dev/tty00) which has the ibutton bus.

		-r

			check for missions on each of the devices on the bus

	1921mission

		Sets the mission (sampling rate) for the device.  This takes one

		required parameter as the  for the device to

		mission.

		

			The serial number of the device to set a mission for

		-r

			Rollover.  When the ibutton reaches it's memory maximum, start

			writing over the oldest entry.  Round-robin fashion.

		-s 

			The rate of sampling.  This is in minutes.

		-d 

			The number of minutes to delay before taking samples.

				The number of minutes to delay before taking samples.

		-l 

		-h 

	sample_devices

		Polls all devices on the bus for changes and logs them to a log

		file.  Optionally, the changes can also be published to a multicast

		group.

		-b 

			Serial device containing the bus to poll (i.e. /dev/tty00)

		-l 

			File to write log entries.  These are general logs.

		-c 

			Directory to write individual snapshots.  These will be named the

			serial number of the ibutton device and will be located in this

			directory.

	1921dump

		Dumps all setting for the mission as well as the current statistics

		and data stored on the device.

		

			The serial number of the device to retrieve all the settings

			for.
