After the new TTY code has been imported, a : hooks interface shall be developed, which will allow these drivers to : work once again. Can't you push off the import until these things are done. There have been too many empty promises in the past to accept this at face value. : - PC98 still uses the sio(4) driver. I've decided not to touch PC98 at : this moment. I'll contact the PC98 folks one of these days, to see if : we can already perform a partial migration to uart(4). : : Wrapping up, I'd like to say I really hope we can one day see these : drivers reappear in FreeBSD. Fortunately we've still got a long time : before 8.0-RELEASE. You are moving too fast on this. Please slow down. You promised documentation and such, but that hasn't happened, so a slowdown in your timeline is justified. thank you for your consideration. Warner
