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 ! + + Alain Degreffe + + eczema(at)ecze.com -- cgit v1.2.3-70-g09d2
