The one trick that I have found is that I have to set the switches to
disable echo and result codes.  set switch 3 UP, switch 4  DOWN.  The
equivalent command is ATE0Q1.  You should  then be  able to configure
CD/DTR to suit your system.   This makes  the modem  a bit  more of a
pain to use, but it will work.  Below  is a  line from  my L.sys with
irrelevant information removed showing what it takes to make it dial.
