serial port opening and closing byte
Hi, all,
I am not sure whether this is the right place for my question. If there is a better place, please let me know.
I am playing with an arm9 embedded Linux device. When I open the serial port, it sends out 1 byte 0 to the RS232 bus. When I close it, it sends out 0xFF. Is this behavior normal? Is there a way to disable it?
Thanks,
Derek
