I have once in a course made a print, where thers is 8 led as can be controlelde by the LPT port, Now i will try to make a device with a led where the computer nows if the led is on or off.

i have think to use the lpt pin 12 (paper end9 as input port.
have read ther shall 5v to the pin before the coputer wil lregister it as 1.

Now i will know if thie print will work.

**broken link removed**

and evt. whihc resistore i should use, and isi necesary with the ordinario diode.

3v. is enough to get the led to ligt strong.
the reason to i ask, is i do not want to neither printport nor the print to
be unfunctional.
