	I want to send flow control information back to a sender across
	an RS232 serial cable.  What signal is appropriate for this?
	Do I use CTS (clear to send), or one of these "secondary" signal
	lines?  All I want to do is to be able to temporarily tell the sender
	not to send my UART data is some relatively standard way.  I am
	using a direct null-modem connection and can get a full 25 pin
	cable.

					Thanks For Any Help!

P.S. Any pointers to good, accessible RS232 docs would be great too...
