LV5: setting bit on parallel port

Hello

I tryed to set a single bit on the parallel Port, but it did not work. What I did:
  • Added the line serialDevices="COM1; COM2; COM3; COM4; COM5; COM6; COM7; COM8; COM9; LPT1; LPT2; LPT3; LPT4;" to C:\Program Files\National Instruments\LabVIEW\labview.ini as proposed here
  • soldered the pins 11+12 to GND 24 for setting the port in a normal state
  • used Pin 18 + 2 as signal D0
  • set the LPT in BIOS to Bidirectional (Unidirectional is not settable)
  • used the serial funktions with Port 10 --> Error 37
  • used the example script --> Nothing happens, even portmon does not log anything
Now i'm quite frustrated, if it doesn't work until tomorrow i'm totally stuck Smiley Sad

Hello,
 
-- [ Added the line serialDevices="COM1; COM2; COM3; COM4; COM5; COM6; COM7; COM8; COM9; LPT1; LPT2; LPT3; LPT4;" ]
 
The line is incorrectly formatted. The last semicolon (after LPT4) shouldn't be there... On the end you only write the double quotation mark.
 
 
Good luck and best regards
