Most reasonable modems deliver their verbose messages *before* asserting
the CD line, so unix programs will never see them unless they have
specifically opened the line with O_NDELAY and set CLOCAL in the termio
flags (SysV) or you have set the modem to always assert CD.  Before
SysVr3.1 and the addition of the \M and \m dialer codes to control
CLOCAL a fake CD signal was required to allow dialing at all - with
current releases there is no excuse for it.
