In all programs using my tio.c module, you can just tell the programs to use 115200 bps, and you won't need the "spd_vhi" kludge (which will go away some day anyway, or at least that's what I hope). So if I am using mgetty (in Linux), I do not have to do setserial spd_vhi in rc.serial (as it is recommended in SErial.HOWTO)? Thanks Mate .
