Thanks again for your immediate reply,
I have a specific hardware connected to my serial port which uses the RTS
pin to control the reset pin of a smart card.
This hardware is known as phoenix interface which doesn't have an external
microcontroller to accept data from the pc and
do some functions such as write or read to the card.These function are
making through pc s/w.
There is only an rs232 translator to give to the cards the TTL signals that
are needed. Tomorow I will test if the h/w makes some malfunction
to the serial port and will come back.
