Are the settings altered by functions from
termios.h kept after file is closed and open again?
I want to use serial communication in a higher level language (Racket) which exposes only reading and writing to/from file ports, but none of the additional functionality (
fnctl). I can use FFI to bind those additional functions and use them, but then I need to close given file and open it again to read/write with Racket functionality - hence my question.
