the CTS2 input value. When CTS2 is set to 1, if transmission is in progress, the line goes to the
mark state after transmission of one frame. When CTS2 is set to 0, the next transmit data is
output starting from the start bit.
Figure 16.10 shows an example of the operation when modem control is used.
