Huh?  Can you point to code or documentation for that?

I've been using serial ports on Linux for 20 years, I've written
multiple tty and serial drivers for Linux, and I've spent a lot of
time in general wandering around the the Linux serial subsystem.  I've
never heard of such a thing before.  It's also not mentioned in the
open() man page. The last parameter to open() controls a newly created
file's mode bits (read/write/execute for user/group/other). That
argument is ignored (and need not even be passed) when opening a file
or device that already exists (as you are when opening a serial port).
