I am writing code to do I/O using an RS-232 port on the IBM PC, and
I need to support the following forms of handshaking:

	software: DC1/DC3
		  ETX/ACK
	hardware: DSR/DTR
		  CTS/RTS

I have read the section entitled "IBM Asynchronous Communications Adapter"
(pp. 1-183 to 1-212) of the IBM PC/XT Technical Reference.  I can find no
information on how to set up handshaking.  Do I have to code the protocol
myself, or have I missed something in the documentation?

Please reply by mail.  I will summarize to the net when the responses dwindle.
