Scott -

Hardware handshaking occurs between the computer and the modem (or whatever
else it's hooked to - another computer, terminal, printer, etc.). It is usually
implemented using CTS/RTS (Clear/Request to send), but some implementations use
DTR (notably printers). In a computer -> modem -\-\-\- modem -> computer
scenario, there's no TRUE hardware handshaking endt to end. Some of the newer
modems can use a wrinkle in their dialog/protocols to effect end to end flow
control.
