I've started from this driver, and it even doesn't support BREAK signal (it is was first reason why I start to write new one -- I needed BREAK to enter kernel debugger).

FreeBSD doesn;'t have any userland API for it, and the same is true for higher and non-standard baud rates. --=20 // Black Lion AKA Lev Serebryakov
