I disagree. Hardware handshakes are a functionality of the UART and are 
therefore always implemented. The hardware handshakes lines are also 
supported by any serial interface of PCs - for good reasons.

It is true that some applications don't necessarliy require handshakes, 
but I am earning money with the use of serial ports and 
hardware-handshakes are indispensible in 95% of all my cases. The only 
applications using XON/XOFF I ever came accross where terminal 
applications and I don't use them no longer since we got rid of modems 
(decades ago).
