|  | 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 ! |
