Hardware Flow Control

Disable Hardware Control — The scanner transmits to the host regardless of any activity on the CTS line.

Enable CTS Flow Control — The CTS signal controls transmission of data to the host.

Enable CTS Scan Control — The CTS line must be active for the scanner to read and transmit data. While the CTS line is inactive, the scanner remains in a host-disabled state; following a successful label transmis- sion, the CTS signal must transition to inactive and then to active to enable scanning for the next label.

Intercharacter Delay

This delay is inserted after each data character transmitted. If the trans- mission speed is too high, the system may not be able to receive all char- acters. You may need to adjust the delay to make the system work properly.

Software Flow Control

Disables/Enables software control using XON/XOFF characters.
