Does mini6410 serial driver support nonstandard speed?

Hi! I need /dev/ttySACx 10400 baudrate.

If i just add 10400 to speed_map struct of stty.c, will it work?
Or i need changes in the serial driver?

"static struct speed_map speeds[] =
{
  {"0", B0, 0},
  {"50", B50, 50},
  {"75", B75, 75},
  {"110", B110, 110},
  {"134", B134, 134},
  {"134.5", B134, 134},
  {"150", B150, 150},
  {"200", B200, 200},
  {"300", B300, 300},
  {"600", B600, 600},
  {"1200", B1200, 1200},
  {"1800", B1800, 1800},
  {"2400", B2400, 2400},
  {"4800", B4800, 4800},
  {"9600", B9600, 9600},
  {"19200", B19200, 19200},
  {"38400", B38400, 38400},
}
