Of course Eli you are right. I made a mistake and were I wrote termios.h it
should have been termio.h and vice-versa.

I appreciate your answer, but I do not know if I am going to know how to
rebuild a library like termio.h. I suppose that many people porting programs
from solaris will have had the same problem.
Does anybody has ported termio.h?

Thank you in advance.
