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).
