+Infinity Usb Unlimited Readme
+-----------------------------
+
+Hi all,
+
+
+This module provide a serial interface to use your
+IUU unit in phoenix mode. Loading this module will
+bring a ttyUSB[0-x] interface. This driver must be
+used by your favorite application to pilot the IUU
+
+This driver is still in beta stage, so bugs can
+occur and your system may freeze. As far I now,
+I never had any problem with it, but I'm not a real
+guru, so don't blame me if your system is unstable
+
+You can plug more than one IUU. Every unit will
+have his own device file(/dev/ttyUSB0,/dev/ttyUSB1,...)
+
+
+
+How to tune the reader speed ?
+
+ A few parameters can be used at load time
+ To use parameters, just unload the module if it is
+ already loaded and use modprobe iuu_phoenix param=value.
+ In case of prebuilt module, use the command
+ insmod iuu_phoenix param=value.
+
+ Example:
+
+ modprobe iuu_phoenix clockmode=3
+
+ The parameters are:
+
+ parm: clockmode:1=3Mhz579,2=3Mhz680,3=6Mhz (int)
+ parm: boost:overclock boost percent 100 to 500 (int)
+ parm: cdmode:Card detect mode 0=none, 1=CD, 2=!CD, 3=DSR, 4=!DSR, 5=CTS, 6=!CTS, 7=RING, 8=!RING (int)
+ parm: xmas:xmas color enabled or not (bool)
+ parm: debug:Debug enabled or not (bool)
+
+- clockmode will provide 3 different base settings commonly adopted by
+ different software:
+ 1. 3Mhz579
+ 2. 3Mhz680
+ 3. 6Mhz
+
+- boost provide a way to overclock the reader ( my favorite :-) )
+ For example to have best performance than a simple clockmode=3, try this:
+
+ modprobe boost=195
+
+ This will put the reader in a base of 3Mhz579 but boosted a 195 % !
+ the real clock will be now : 6979050 Hz ( 6Mhz979 ) and will increase
+ the speed to a score 10 to 20% better than the simple clockmode=3 !!!
+
+
+- cdmode permit to setup the signal used to inform the userland ( ioctl answer )
+ if the card is present or not. Eight signals are possible.
+
+- xmas is completely useless except for your eyes. This is one of my friend who was
+ so sad to have a nice device like the iuu without seeing all color range available.
+ So I have added this option to permit him to see a lot of color ( each activity change the color
+ and the frequency randomly )
+
+- debug will produce a lot of debugging messages...
+
+
+ Last notes:
+
+ Don't worry about the serial settings, the serial emulation
+ is an abstraction, so use any speed or parity setting will
+ work. ( This will not change anything ).Later I will perhaps
+ use this settings to deduce de boost but is that feature
+ really necessary ?
+ The autodetect feature used is the serial CD. If that doesn't
+ work for your software, disable detection mechanism in it.
+
+
+ Have fun !
