Well, I think I should have explained myself better, sorry.
The main problem I have is that I'm unable of transmiting anything via RS-232, and, after analizing the circuit I guess the problem has to be that pin 14 is not doing the transmision as it doesn't change when the PIC is working (I have debugged the code and PIC is doing the transmision), in fact, according to the datasheet it's even working outside of range when I connect the DB9 to it ( if you look at the datasheet it should work at a minimum of -0,6 V (my Vs- is measured as -0,3) and I'm when I connect it to the DB9 pin it works far below from it, so, I guessed the problem had to be that so I'd have liked to know what might have been causing this behaviour to have it fixed.
But now if you tell me that this should be -V, that the voltage is correct there, then I guess the problem has to be another one.
Thanks.
