[ts-7000] help me in PC104

["hishamelgaurf" <>]

hi all

I am trying to use PC104 on ts7250 to only output some data, but i
can't , i got tired from trying it, when i send 0xff to PC104, it
makes one of data lines 3.2 v and the others around 0.8 , and this
value not considered as logic '1' by any interfacing circuits, the
code i used is the following 

#include<unistd.h>
#include<sys/types.h>
#include<sys/mman.h>
#include<stdio.h>
#include<fcntl.h>
#include<string.h>
int main()
{
   volatile unsigned char *P1DR,*P2DR;
   unsigned char *start;
   int fd = open("/dev/mem", O_RDWR);
   start = mmap(0, getpagesize(), PROT_READ|PROT_WRITE, MAP_SHARED,
fd, 0x11c00000);
   P1DR = (unsigned char *)(start + 0x01);     // port 1 address

  *P1DR=0xff;//make port 1 all ones


   close(fd);
   return 0;
}
i have compiled this successfully using root permissions  , please any
one have an idea about a solution , don't hesitate to write to me
thanks in advance
