Look I don' t want to seem grumpier than I usually am , but if you come "here", you get help for what is "here", if you go "there", you may get help for what is "there".
FORGET each and every video tutorial you have found ANYWHERE, you should follow THIS guide:
or the one in first post of this thread, for which I gave you a link to the Spanish translation and ONLY these guides and NOTHING ELSE.
That video was made by the good guys from Greece that sell the kit for a mere 5 (five) times the cost of the components and provide with it a - most probably half-@§§ed - program called "FWbugfix" (as stated in the sub-titles of the video, which seems a lot like a "wrap around" *a* terminal program).
If you buy from them for a mere 29.99 US$ the adapter, you will get also that program (which is NOT needed as Hyperterminal or Putty would do nicely).
