Software Flow Control
The host can enable or disable flow control with command #614N Select Flow Control
Option.
The host can use software control characters (XON/XOFF) to interrupt reader transmissions.
When the reader is configured for software flow control, it stops transmitting if it receives
the XOFF character from the host (host software command 13H). It resumes transmitting
only when it receives the XON character (host software command 11H) from the host. If flow
control is not needed, the reader should be configured for no flow control (#6140 Disable
Flow Control).
Note: TransCore recommends that XON/XOFF flow control be disabled while using the
ECP.
Use the following procedure to set flow control parameters using the terminal emulation
program. Refer to section
“614N Select Flow Control Option” on page 7–24 .
To select flow control
1. Ensure that the host device is in command mode.
2. Enter command #6140 to disable flow control, command #6141 to enable software flow
control (factory default) and press ENTER.
