[rtl] Problems with time and timer!

[Kurt Renauer <e9125432@student.tuwien.ac.at>]

Hi to everyone!

I am using RT Linux just a few days and there are some problems that I
could NOT solve: 
1. I started the rect_wave sample ... measured the signal with a
logicanalyzer and found out that the measured period time did not match
the period time of the rt_task_make_periodic function.
What I did: 
I modified the program: just one task ... toggling a bit on LPT D0 with a
period of 100 us -> the measured period was then 85us.
????

2. I used the timer related functions:
I used this timer functions within the program I described before. What I
did: ... rt_request_timer ... rt_set_timer... I wrote a timer handler that
toggles a LPT Bit ... etc. ... 
OK! the timer worked, but the periodic tasks did not run?!
Why not?

If any one could help, it would greatly be appreicated;
