Response

Three levels, Slow, Normal and Fast, of port response time are designed for user's need. Ports with faster response time will consume more host CPU's resource while slower response consumes less resource. The response time for those ports with normal or slow response can be further tuned by the response level in “Performance Tuning” menu. In addition, if the port feature is set to On-board Line Discipline “Disable” and Feature “Terminal”, response option will be locked at "Slow" level.

UART FIFO

You can set this feature to “Enable” (default) and gain most performance for the board. Or you can set this feature to “Disable” to avoid from data loss when communicating with plain communication devices using S/W flow control.

RTS/CTS Hardware Flow Control

This feature is for more flexible driver behavior. If set to “Disable” (default), CTS signal is not needed for tty port to transfer data and RTS/CTS hardware flow control function in driver is disabled. On the contrary, if set to “Enable”, CTS signal is needed for tty port to transfer data and RTS/CTS hardware flow control function in driver is enabled.
