Screen- and Printercontrol from dBaseIII under MS-DOS

If you know answers to the following questions, please mail them to
me:

- How do you send escape sequences to the screen?
  Even after loading ANSI.SYS, in escape sequences, like

	? chr(27)+'[5m'

  for blinking text, the control character (ESC) appears on the
  screen as one of those funny symbols in the IBM-PC charset. This
  is on an Olivetti M24 and dBaseIII Version 1.1. How can you
  arrange for the escape sequence to be *interpreted*?

- How do you send control-chars to the printer?
  Some of the control characters are interpreted by dBase and not output
  'as is'.
  E.g. the TAB (chr(9)) is replaced by some spaces, chr(0) is swallowed.
  On my printer (Gemini Star 10X) underlining is ESC+CHR(0), which I tried to
  produce like this:

	set print on
	? chr(27)+chr(0)
	set print off

  But the chr(0) never makes it to the printer.

Any help is greatly appreciated.
