Inter-message delay
The maximum rate at which data can be transmitted by the MicroBar NX is affected by the
response of the system. An inter-message delay gives the host system time to process
each successive message it receives—useful for example when a control code (such as
Enter) requiring a response from the host is sent after each record.
response of the system. An inter-message delay gives the host system time to process
each successive message it receives—useful for example when a control code (such as
Enter) requiring a response from the host is sent after each record.
Each time the MicroBar NX receives a message, an inter-message delay cycle is activated.
If the MicroBar NX receives a new message before the end of the inter-message delay, it
stores the previous message in a "rolling buffer" memory and the cycle starts again. When
no more messages are received before the end of an inter-message delay cycle, all the
messages stored in the buffer are transmitted to the host system. The messages are
transmitted First-In-First-Out and each message is separated by the inter-message delay.

This feature can be used with all host interfaces.
