SPARC is special, it does not have Bnnn constants for baud rates above 2000000. Instead it defines 4 Bnnn constants with smaller baud rates. This difference between SPARC and non-SPARC architectures is present in both glibc API (termios.h) and also kernel ioctl API (asm/termbits.h). Signed-off-by: Pali Rohár <pali@xxxxxxxxxx>
Patch applied! Thanks, Alex
