Handshaking
Some type of flow control or “handshaking” must be used between two
devices to prevent data from being transmitted before the receiving device
is ready to accept it. Handshake signals interrupt the flow of data until the
receiving device is ready.
SELECTION CODE: E4
X-On/X-Off A
RTS/CTS B
Stop Bit
The stop bit function defines the number of bits used to end the data frame.
Older equipment sometimes requires extra time after receiving a character in
order to process it, and therefore requires two stop bits.
SELECTION CODE: E5
1 bit A
