Hi everyone,
(except advertising spammers...)
I use the command line: COPY anyfile.dat COM2 to send in a simple way a stream of data to a device. It works fine. Only the Tx line is used here.
The serial port setting as reported by the command MODE COM2 is:
Serial port status COM2:
---------------------------- Baud : 115200 Parité : None Bits de données : 7 Bits d'arrêt : 1 Temporisation : OFF XON/XOFF : OFF Protocole CTS : OFF Protocole DSR : OFF Sensibilité DSR : OFF Circuit DTR : OFF Circuit RTS : ON
I would like to know a bit more about the RTS line that goes high (negative to positive voltage that is) during the transmission. I would like to use it to control a gating circuit at the receiving end.
So my question is: Is the RTS line goes high *before* the first byte is sent and goes low
*after* the last byte has been sent?
