Specifying O_NDELAY solves the problem for one process, but it does not
help if one does not have the source; some system programs that do their
own ioctl's (most notably, /etc/getty), will let you specify some of the
ioctl flags according to your local configuration, but not the open
flags.
The problem essentially is: How do you convince getty to open a port
without waiting for carrier, if you do not have the carrier signal
wired, and your terminal driver expects to see it before proceeding? (I
do not claim there is no way, I'm rather new to sys V.3).
