I have just upgraded my kernel from 2.4.7 to 2.4.18
After the upgrade I started having problems with
my "signal_handler_IO".
In the old version, this seemed to trigger only when
bytes were waiting on the serial port. It now seems
to trigger on send as well as receive increasing my
overhead.
I saw where TTY_DO_WRITE_WAKEUP was
added to kernel/serial.c.
Was this to create the action I am seeing? If so,
is there a way that only received characters can
trigger SIGIO and not a Tx ready or Tx send?
Regards,
J. Deas
