Hello, Harald. You wrote 17 =D1=81=D0=B5=D0=BD=D1=82=D1=8F=D0=B1=D1=80=D1=8F 2013 =D0=B3.,= 21:43:17: HS> Is that worth a try? HS> http://www.asix.com.tw/FrootAttach/driver/MCS7840_7820_FreeBSD_driver_v= 1.1.zip Nope. 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 <lev@FreeBSD.org>
