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.

●

Timeout (default is 9)

This option sets the protocol timeout between the host driver and Blue Heat/Net firmware. For

some networks this value may need to be modified for better operation. A higher value will

provide a longer time for the host driver to wait for a response from the Blue Heat/Net unit. The

default value is 9 seconds and works well for most network setups.
