    hi all, i am trying to read and write data to /from the parallel port , i am running j9 vm on linux.under /dev there are lp0..lp3 parport0..parport3, and port devices , i dont know which one to use , i have tried all , they all return with an ioexception saying "cannot find the file" except for port device which does not generate any error but it does not return what i have written on it ,
    any help would be much appreciated.
    i am using fileoutputstream and printwriter calsses .
    (note: i dont have java.com.api package and not considering of using it )so any other solution is highly desirable.
