Hello, I'm trying to access a hardware board of my company through a serial connection using a Python script and the pyserial module.
I use Python 2.7.1 with Ubuntu 11.04 (pyserial is the package python- serial with version 2.5.2, http://pyserial.sourceforge.net/pyserial_api.html). The board to which I'm trying to connect works correctly with serial as some other guys did some TCL scripts to manage it. My problem is that every time I open a new connection, the device is reset. I'd like to not have the device reset. The code is the following : handler = serial.Serial(port=self.portname, baudrate=9600, bytesize=serial.EIGHTBITS, parity=serial.PARITY_NONE, stHello, I'm trying to access a hardware board of my company through a serial connection using a Python script and the pyserial module.

Is there any possibility to not reset the device when opening the connection ?
