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?

I dunno about MS software, but normally, if no hardware handshaking,
RTS is just a bit in the UART that you can set and reset, it
will stay set or reset all the time.
The above list you show suggests RTS is 'on' all the time.
