Hi. I have an app who write to a device throw the serial port. Sometimes it stop working, and when I see the configuration of the serial port the ohpaged flag is enable(+). After my stty -ohpaged < /dev/ser1 it start working again and its fine. Well: After a time (let say 1 day working fine), it failed again. And guest what: ohpaged is enabled egain.
Who set this flag ??. Not me.
