libnodave is amazing, i might be connected on SIEMENS PLC in seconds. If I connect with c#, i might send the information from PLC for email, for example, store in database and a lot other things. I replace a SIEMENS TD17 for a apliction wich I've wrote. Thanks a lot Thomas.

Great library. Low level. Hard examples.

Very good project. I use it with Delphi. No problem with Delphi 7. With Delphi XE5 or following, unicode is used by default. To get it working under that version, I had to change all occurences of char, pchar and string to ansichar, pansichar and ansistring in source codes. Normally that should work with Delphi 7 as well. Thanks a lot.
