614N Select Flow Control Option
Command
#614N
selects the flow control option for reader-to-host communications. The factory default
setting is software flow control (XON/XOFF) enabled. In download mode, flow control is not host-
selectable; it is fixed at the default setting. However, during data mode and command mode operation, the
following flow control options are available. The
N

Table 29 Flow Control Commands
Command
Flow Control Option
6140
Disable flow control
6141
Enable software flow control (factory default)
6142
Enable hardware flow control
Reader response:
Done
If the reader is configured for software flow control (XON/XOFF), it stops transmitting if it receives an XOFF
character (host software command 13H). It does not resume transmitting until it receives an XON character
(host software command 11H). If the reader is configured for hardware flow control (RTS/CTS, request to
send/clear to send), it stops transmission if it detects that the CTS line is no longer asserted. It resumes
transmission when this line is asserted again.
Note:
TransCore recommends that XON/XOFF flow control be disabled while using the ECP.
6170 Disable Echo Mode
Command
#6170
disables the reader’s echo of received host commands. If operating in basic protocol
or data inquiry protocol, the reader echoes by default. As the reader receives a host command, it echoes
each character of the command. Once the entire command has been received and processed, the
reader transmits its response. If echoing is disabled with command
#6170
, the reader does not echo
