Whatever is happening is more complicated that that.

/usr/lib/uucp/Uutry simply runs uucico.
/usr/lib/uucp/uucio opens the port with NDELAY (given an appropriate
line in Devices), which is supposed to tell the port to not bother
waiting for DCD.

As far as I know, only the Supra is associated with this problem.
Other modems, including those programmed by /usr/lib/uucp/fix-*,
leave DCD false until carrier is finally detected, and uucico
works whether uugetty is on or not.
