hello group, how to get ttyS0 serial port for exclusive access? I have a python script that uses this device with AT commands. I need that two instances can call simultaneosuly this python script but only one of them gets the device. I tried fcntl.flock, it was just ignored, put writtable file LCK..ttyS0 in /var/lock, tried ioctl (but I may not know what are appropriate arguments), googled half a day for various phrases, error messages etc....without success.
please help, Andra -- http://mail.python.org/mailman/listinfo/python-list
