I think that you have a brain-damaged SVR3 box.  You should have two 
flags that you can use:
  O_NDELAY which says to open a file without waiting for silly little
things like CD active on a modem line and:
  CLOCAL (in the termio.h stuff) which says to ignore modem control.
This makes it very easy to open a MODEM line and dial out while ignoring
modem control.
  I have a short program that allows uses this trick to let you do 
'stty's on a modem line whether or not it has a carrier.  This is REAL 
useful sometimes when you're trying to figure out what uugetty/uucico is
doing wrong.
