3-26 Intellio C320Turbo User's Manual
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
This feature is set to “Enable” by default and is not able to change.
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.
Performance Tuning
The utility let you tune the favored response time for those ports with
Response=Normal or Slow in [Port Feature] sub-menu of Advanced configuration.
Ten response time levels (0-9) are available for tuning. The idea is that the faster
response time will consume more host CPU resource while slower response consume
less resource. If the host CPU is fast enough or a quick response is highly demanded,
choose level 9 would be suitable.
