Example 2: What happens if you have not completed entering
the data at the keyboard and the next package arrives?
If the next package is a valid read, it will be sent to the discretes I/O
and the host. The package count will increment. This will continue
with each subsequent valid read. When the manual data entry is
complete, it will be sent to the host with the package count of the last
package read.

If the next package (or any of the packages processed before the
manual data entry is completed) is a no-read, the decoder will send
only a single message. The opportunity for entering data for
additional no-reads that occurred during manual data entry will be
lost. In other words, if you can enter data manually more quickly
than no-reads occur, then you will lose no data. If two no-reads occur
before you have completed entering data for the first, then you will
have no opportunity to enter data for the second no-read in the
sequence.
