Tom:

This is probably what you are looking for.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/devio/base/dcb_str.asp

In particular:

(For XON/XOFF)
fOutX
Indicates whether XON/XOFF flow control is used during transmission. If this member is TRUE, transmission stops when the XoffChar character is received and starts again when the XonChar character is received.
fInX
Indicates whether XON/XOFF flow control is used during reception. If this member is TRUE, the XoffChar character is sent when the input buffer comes within XoffLim bytes of being full, and the XonChar character is sent when the input buffer comes within XonLim bytes of being empty.

fRtsControl
RTS (request-to-send) flow control. This member can be one of the following values. Value Meaning
RTS_CONTROL_DISABLE Disables the RTS line when the device is opened and leaves it disabled.
RTS_CONTROL_ENABLE Enables the RTS line when the device is opened and leaves it on.
RTS_CONTROL_HANDSHAKE Enables RTS handshaking. The driver raises the RTS line when the "type-ahead" (input) buffer is less than one-half full and lowers the RTS line when the buffer is more than three-quarters full. If handshaking is enabled, it is an error for the application to adjust the line by using the EscapeCommFunction function.
RTS_CONTROL_TOGGLE Specifies that the RTS line will be high if bytes are available for transmission. After all buffered bytes have been sent, the RTS line will be low.
Windows Me/98/95: This value is not supported.

fOutxCtsFlow
If this member is TRUE, the CTS (clear-to-send) signal is monitored for output flow control. If this member is TRUE and CTS is turned off, output is suspended until CTS is sent again.

And Possibly ...

fDtrControl
DTR (data-terminal-ready) flow control. This member can be one of the following values. Value Meaning
DTR_CONTROL_DISABLE Disables the DTR line when the device is opened and leaves it disabled.
DTR_CONTROL_ENABLE Enables the DTR line when the device is opened and leaves it on.
DTR_CONTROL_HANDSHAKE Enables DTR handshaking. If handshaking is enabled, it is an error for the application to adjust the line by using the EscapeCommFunction function.

fOutxDsrFlow
If this member is TRUE, the DSR (data-set-ready) signal is monitored for output flow control. If this member is TRUE and DSR is turned off, output is suspended until DSR is sent again.

Let me know if you need any other help, hopefully these are enough to get you by!
