RS-232 Handshaking
RS-232 handshaking is a set of rules concerning the exchange of data
between serially communicating devices.
If using RTS/CTS handshaking, the imager issues an active RTS signal
to the receiving device. The imager waits to send its data until it detects
an active CTS signal from the receiving device. The imager then sends
its data while checking the CTS signal before the transmission of each
data character. If an inactive CTS signal is detected at any time, the
imager halts transmission until it detects another active CTS signal.
When the imager has finished transmitting data, it issues an inactive
RTS signal to the receiving device. Default = RTS/CTS Off, XON/XOFF
Off, and ACK/NAK Off.
