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.
