The flow contol is set by SetCommState() usiing control parameter

-- no flow control 
SetCommState(hComm, "baud:9600,parity:even,bits:8,stop:1,control:none") 
-- software flow control (xon/xoff) 
SetCommState(hComm, "baud:9600,parity:even,bits:8,stop:1,control:soft") 
-- hardware flow control DTR/RTS handshake, CTS and DSR are monitored.  
SetCommState(hComm, "baud:9600,parity:even,bits:8,stop:1,control:hard") 

NOTE from: http://msdn.microsoft.com/en-us/library/aa363214(VS.85).aspx
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.
