Thanks Dave. It is not in TXSTA but in RCSTA, bit 7 where the UART is enabled/disaled. But as I stated before, once it is enebled and there are even 1 Hserout command somewhere in the program, I cannot gain control of the port pin. May be I got a defective chip, maybe there is a ghost around. I cannot explain it.

Before posting usually the manual/data sheet is really dusted good. In vein...

I will try tomorrow with different system (MCU/PC/Programs).
