Purpose: Regulates the data transmission through the serial port. The terminal is a DTE Data
Terminal Equipment) device. There are several flow control options:
•
•
•
•
•
Syntax: YLn.data
where n is:
1
2
Acceptable values for data are:

Clear To Send (CTS) is a hardware signal flow control. The terminal sets and clears
Request To Send (RTS) when it is ready to receive. The terminal checks CTS when
it tries to transmit data.
XON/XOFF response causes the terminal to respond to XON/XOFF characters
received while transmitting.
XON/XOFF control specifies that the terminal transmits XON/XOFF characters to
control the incoming data flow.
XON/XOFF response and control specify that the terminal responds to and
transmits XON/XOFF characters.
CTS/RTS for DTE-DTE allows for peer connections. Each terminal's RTS output
pin is connected to the CTS input pin of the other terminal. Then each terminal sets
RTS whenever it is ready to receive data and waits for CTS to be set before sending
data.
