Special Options
With the exception of Use FIFO Buffers, these options are typically left unselected. They are
provided to maintain compatibility with applications that require strict synchronization between
the Blue Heat/Net and the application. Some degradation of throughput will occur when these
options are selected.
●
Use FIFO Buffers
(default is selected)
The Blue Heat/Net makes use of UARTs with configurable FIFOs. Selecting or deselecting this
option will enable or disable FIFO buffers of the UART respectively.
●
Tx Sync Mode
(default is unselected)
In this mode data will not be marked as sent until the Blue Heat/Net has actually sent the data.
This allows for tight synchronization between the application and the data transmission.
Data is reported as soon as it is sent to the Blue Heat/Net when this mode is
not
turned on.
Leaving this mode unselected improves throughput.
●
Set Xon/Xoff Mode
(default is unselected)
This mode must be turned on if EscapeCommFunction(SETXON\XOFF) is used by the
application connecting to the Blue Heat/Net port. This allows the Blue Heat/Net to keep the flow
control state synchronized with these IOCTLs.
It is best to leave this option unselected if this specific EscapeCommFunction(SETXON\XOFF) is
not used, because the extra work needed to maintain the flow state slows communications down.
●
Apply to All Ports
(default is unselected)
This will apply the above two settings to all ports of the same Blue Heat/Net box.
