Be sure to keep in mind: the `real' TTY devices are ttyU0 and ttyU1. The cua* devices are callout devices, which unlike the tty* devices don't wait for a carrier detect signal during open(). My opinion is that the USB serial driver shouldn't use a bitmask to keep track of which unit number are available, because we've got a nice KPI for that: http://www.freebsd.org/cgi/man.cgi?query=new_unrhdr Unfortunately I cannot answer your question. Hopefully Hans can. ;-) Cheers, -- Ed Schouten <e...@80386.nl> WWW: http://80386.nl/
