entering bios with Labview serial vis

   I have a piece of equipmet I am
attempting to test with Labview.  Part of the test I am writing
requires me to enter the bios and read/set  the settings.  I
am able to enter the bios with hyperterminal and see all the responses
and such.  However, whenever I attempt to send or receive
information to the bios in labview with either the serial vis or visa I
get no response or echo to anything entered. 
   One developer suggested that there is a handshake required
that hyperterminal does automatically to get this info to echo out the
serial port.  His suggestion was when 5n is sent out the serial
port that it must be repied with a \033[0n.  This worked for him
when automating with expect.  However, in labview, this does not
work.  Has anyone ran across this.  It definately looks like
some type of handshaking that is performed with hyperterminal.
