See attached diff file for getty.c in FreeBSD 2.0.5. I don't think, that waiting for carrier is right way. Better way will be to open device as non-blocked, then setup all tty flags (incl. speed), then reopen device in blocked mode just before reading anything. BTW, Bruce, is it possible now to switch to blocked mode without reopening? -- Andrey A.
