The scanner stays ON (is able to receive data) except during certain parts of
the process, such as receiving data (buzzer command execution), transmitting
data, and menu processing. The scanner checks the CTS line before
transmitting data. When it is ON, the scanner transmits data. When it is OFF,
the scanner waits for it to turn ON within a set time. The scanner will abort
transmission with an error indication (buzzer) when the CTS line is not ON
within a specified period. The Flow Control time-outs are as follows, and the
default setting is “indefinitely“ (I0).
