Termination Type Field

If none of the bits are set (Type=0), the port will be configured for stream mode.

Any characters received on the port are immediately sent to the processor. The

processor must buffer and assemble a packet of information if this mode is

selected. If the data can be handled by the processor in this mode and it is

appropriate for your application, this is the fastest method of communication

between the device and the processor. However, stream mode tends to be

processor-intensive and does not work well in larger applications due to the

potential for loss of data. For larger applications, consider using one of the other

modes that allows the module to buffer incoming data from complete messages

before transferring it to the processor.
