Thanks for that pointer. Implied there is that the FNDELAY comes from some desire for BSD compatibility which it seems reasonable for Android not to be too worried about. I was surprised that Android's termios sys calls didn't support TCSAFLUSH, so we had to switch to TCSANOW on Android. The recent change (adding FNDELAY) was added to accommodate a different Linux platform which didn't honor the termio setting of VMIN=0 and VTIME=0 settings which define non blocking I/O. > I can't see the surrounding code, so there may be a bit more > work involved. Nope. The name change was all that was needed. -Mark > > On Sat, Sep 1, 2018 at 6:38 PM, vince <[email protected]> wrote: > > > > can anybody help here ? .....
