RS232 Handshaking
RS232 Handshaking allows control of data transmission from the scanner using software commands from the host device.
RTS/CTS Off: RTS/CTS is turned off so no data flow control is used, but RTS is still active.
RTS/CTS Off, RTS Inactive: RTS/CTS is turned off so no data flow control is used and RTS is inactive.
Flow Control, No Timeout: The scanner asserts RTS when it has data to send, and will wait indefinitely for CTS to be
asserted by the host.
Character-Based Flow Control, No Timeout: The scanner asserts RTS when it has a character to send, and will wait
indefinitely for CTS to be asserted by the host
Two-Direction Flow Control: The scanner asserts RTS when it is OK for the host to transmit. The host asserts CTS
when it is OK for the device to transmit.
Flow Control with Timeout: The scanner asserts RTS when it has data to send and waits for a delay (see RS232
Timeout on page 2-26) for CTS to be asserted by the host. If the delay time expires and CTS is not asserted, the device
transmit buffer is cleared and scanning may resume.
Character-Based Flow Control with Timeout: The scanner asserts RTS when it has a character to send and waits for a
delay (see RS232 Timeout on page 2-26) for CTS to be asserted by the host. If the delay time expires and CTS is not
asserted, the device transmit buffer is cleared and scanning may resume.
