0005 Hi all,
0006
0007
0008 This module provide a serial interface to use your
0009 IUU unit in phoenix mode. Loading this module will
0010 bring a ttyUSB[0-x] interface. This driver must be
0011 used by your favorite application to pilot the IUU
0012
0013 This driver is still in beta stage, so bugs can
0014 occur and your system may freeze. As far I now,
0015 I never had any problem with it, but I'm not a real
0016 guru, so don't blame me if your system is unstable
0017
0018 You can plug more than one IUU. Every unit will
0019 have his own device file(/dev/ttyUSB0,/dev/ttyUSB1,...)

0023 How to tune the reader speed?
0024 =============================
0025
0026 A few parameters can be used at load time
0027 To use parameters, just unload the module if it is
0028 already loaded and use modprobe iuu_phoenix param=value.
0029 In case of prebuilt module, use the command
0030 insmod iuu_phoenix param=value.
0031
0032 Example::
0033
0034 modprobe iuu_phoenix clockmode=3
0035
0036 The parameters are:
0037
0038 clockmode:
0039 1=3Mhz579,2=3Mhz680,3=6Mhz (int)
0040 boost:
0041 overclock boost percent 100 to 500 (int)
0042 cdmode:
0043 Card detect mode
0044 0=none, 1=CD, 2=!CD, 3=DSR, 4=!DSR, 5=CTS, 6=!CTS, 7=RING, 8=!RING (int)
0045 xmas:
0046 xmas color enabled or not (bool)
0047 debug:
0048 Debug enabled or not (bool)
0049
0050 - clockmode will provide 3 different base settings commonly adopted by
0051 different software:
0052
0053 1. 3Mhz579
0054 2. 3Mhz680
0055 3. 6Mhz
0056
0057 - boost provide a way to overclock the reader ( my favorite :-) )
0058 For example to have best performance than a simple clockmode=3, try this::
0059
0060 modprobe boost=195
0061
0062 This will put the reader in a base of 3Mhz579 but boosted a 195 % !
0063 the real clock will be now : 6979050 Hz ( 6Mhz979 ) and will increase
0064 the speed to a score 10 to 20% better than the simple clockmode=3 !!!
0065
0066
0067 - cdmode permit to setup the signal used to inform the userland ( ioctl answer )
0068 if the card is present or not. Eight signals are possible.
0069
0070 - xmas is completely useless except for your eyes. This is one of my friend who was
0071 so sad to have a nice device like the iuu without seeing all color range available.
0072 So I have added this option to permit him to see a lot of color ( each activity change the color
0073 and the frequency randomly )
0074
0075 - debug will produce a lot of debugging messages...
0076

0078 Last notes
0079 ==========
0080
0081 Don't worry about the serial settings, the serial emulation
0082 is an abstraction, so use any speed or parity setting will
0083 work. ( This will not change anything ).Later I will perhaps
0084 use this settings to deduce de boost but is that feature
0085 really necessary ?
0086 The autodetect feature used is the serial CD. If that doesn't
0087 work for your software, disable detection mechanism in it.

0090 Have fun !
