The following outlines the steps used to OUTPUT data for software and hardware handshaking.
XON/XOFF Handshaking:
1. If an XOFF has been received from the device,
then the computer waits for an XON to be received.
2. The data is then sent.
Hardware Handshaking:
1. DTR and RTS are turned on.
2. The computer waits for the device to turn on DSR and CTS.
3. The data is then sent.
4. DTR and RTS are turned off.
