Using CTS as busy signal

[TORNIS]

                 Hello !

       I'm using uALFAT USB with the latest firmware, interface UART. I have question about using CTS singal. For example:
requesting time&date in human format, uALFAT confirm request, send string and again confirmation, all ok.
After reception of the requested string, my system leaves in a busy mode and tries to set busy signal to uALFAT
by setting line CTS to HIGH. But uALFAT accept my busy signal on CTS after sending the second confirmations.
(uALFAT continue send at time the CTS line is HIGH) Should the system react to busy signal on CTS line instantly?

uALFAT has a hardware fifo of 8 (or 16 I do not remember) so once you set CTS high, uALFAT will stop responding by those bytes in the hardware FIFO will still come out
