The user Receives data
Radio
CTS
RxD
The CTS signal indicates that the user reception buffer is full. Therefore, the modem does not send data on the serial link
during that time. However, the basic radio operation (synchronization, signal lock, etc.) and the data transmission on the radio
(with data reception on the serial link) continues to operate normally. On the other hand, if another modem sends a data
frame on the radio, this radio frame is not handled (and then not acknowledged). The Transmitter Modem considers this radio
frame as lost and indicates it to the user. (Ack_Tx signal).
It would be better to avoid making the CTS inactive as much as possible.
