  Hallo to All

I don't know why if i use a converter USB-Serial RS232, on my
computer, comunication on PLC with libnodave not function;
but i connect directly my cable (a PC Adapter) to RS232 card
the comunication is ok.
i' ve try to use USB-Serial RS232 converter with Step 7 and also in this case the comunication is ok.

I' m using libnodave from delphi 5.

Someone can help me ?

Thanks for your help.
