   4Hi all,
   5

   7This module provide a serial interface to use your
   8IUU unit in phoenix mode. Loading this module will
   9bring a ttyUSB[0-x] interface. This driver must be
  10used by your favorite application to pilot the IUU
  11
  12This driver is still in beta stage, so bugs can
  13occur and your system may freeze. As far I now,
  14I never had any problem with it, but I'm not a real
  15guru, so don't blame me if your system is unstable
  16
  17You can plug more than one IUU. Every unit will
  18have his own device file(/dev/ttyUSB0,/dev/ttyUSB1,...)

  22How to tune the reader speed ?
  23
  24 A few parameters can be used at load time
  25 To use parameters, just unload the module if it is
  26 already loaded and use modprobe iuu_phoenix param=value.
  27 In case of prebuilt module, use the command
  28 insmod iuu_phoenix param=value.
  29
  30 Example:
  31
  32 modprobe iuu_phoenix clockmode=3
  33
  34 The parameters are:
  35
  36 parm:           clockmode:1=3Mhz579,2=3Mhz680,3=6Mhz (int)
  37 parm:           boost:overclock boost percent 100 to 500 (int)
  38 parm:           cdmode:Card detect mode 0=none, 1=CD, 2=!CD, 3=DSR, 4=!DSR, 5=CTS, 6=!CTS, 7=RING, 8=!RING (int)
  39 parm:           xmas:xmas color enabled or not (bool)
  40 parm:           debug:Debug enabled or not (bool)
  41
  42-  clockmode will provide 3 different base settings commonly adopted by
  43   different software:
  44        1. 3Mhz579
  45        2. 3Mhz680
  46        3. 6Mhz
  47
  48-  boost provide a way to overclock the reader ( my favorite :-)  )
  49   For example to have best performance than a simple clockmode=3, try this:
  50
  51      modprobe boost=195
  52
  53   This will put the reader in a base of 3Mhz579 but boosted a 195 % !
  54   the real clock will be now : 6979050 Hz ( 6Mhz979 ) and will increase
  55   the speed to a score 10 to 20% better than the simple clockmode=3 !!!
  56
  57
  58-  cdmode permit to setup the signal used to inform the userland ( ioctl answer )
  59   if the card is present or not. Eight signals are possible.
  60
  61-  xmas is completely useless except for your eyes. This is one of my friend who was
  62   so sad to have a nice device like the iuu without seeing all color range available.
  63   So I have added this option to permit him to see a lot of color ( each activity change the color
  64   and the frequency randomly )
  65
  66-  debug will produce a lot of debugging messages...

  69 Last notes:
  70
  71 Don't worry about the serial settings, the serial emulation
  72 is an abstraction, so use any speed or parity setting will
  73 work. ( This will not change anything ).Later I will perhaps
  74 use this settings to deduce de boost but is that feature
  75 really necessary ?
  76 The autodetect feature used is the serial CD. If that doesn't
  77 work for your software, disable detection mechanism in it.
