In HyperTerminal it's one of the settings in the dialog box that sets the baud rate, etc. In 3.1 (and most likely the 3.1 Terminal running under 95 or NT) it's in the Control Panel. It's also possible to bypass the hardware flow control by jumpering the flow control lines on the plug that plugs into the PC. For test purposes it's easier to just set the software to not use it. When it's set up properly, making a loopback by connecting the PC's receive data to the PC's transmit data will let you see everything typed. If you see everything twice, turn the local echo off.
