TIOC[SG]RS485 are #defined in <asm-generic/ioctls.h>, so #include <asm-generic/ioctls.h> here and/or below (in userspace program).
I noticed that for some architectures (e.g., cris) these ioctls are defined also in arch/cris/include/asm/ioctls.h, and with different values with respect to the values defined on asm-generic/ioctls.h. Therefore, I wasn't completely sure that the values defined in asm-generic are being used in every driver... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Oh, OK, I see. Thanks for the info. ~Randy
