That's what we all strive for, isn't it? :-)

The following works ... I would like to have a little more standard string handling in ANTLR 3 lexers (I liked ANTLR 2 more here ...):

STRING @init { string result = ""; }        // we build the text "manually"
    : '"'
      ( c=~('"')   { result += (char) $c; } // a non-" char
      | '\\' '"'   { result += '\"'; }      // an escaped "
      )*
      '"'          { $text = result; }
    ;

Regards
Harald
