18-4 Control Using CTS and RTS

Depending on the "Ct5" parameter of "Serial interface ( 5if )", the balance performs as follows:
Ct5 0
Regardless of whether the balance can receive a command or not, the balance keeps the CTS line
HI. The balance outputs data regardless of the condition of the RTS line.
Ct5 1
The CTS line is kept Hi normally. When the balance can not receive the next command (e.g. while
the balance is processing last command), the balance sets the CTS line to Lo. The balance confirms
the level of the RTS line before outputting a set of data. If the RTS level is Hi, the balance outputs
data. If the RTS level is Lo, data is not output (The data is canceled).
