7.4.3.4 Continuous Read
The reader device reads and displays serial numbers continuously while one or more
tags remain in the field. This command stops if any character is sent to the reader
module.
The reader supports different tag types at the same time. To increase the reading
performance switch to a single tag mode. If more than one tag of the same tag type
should be detected at the same time the Multitag flag must be activated. The
response data length depends on the tag type.

'N' Error: No Tag in the field (only binary protocol)
7.4.3.4.1 Multitag continuous read mode
If the Multitag flag is set in the Protocol Configuration (PCON) register the reader
reads multiple tags continuously.
7.4.3.4.2 Auto start
The continuous read mode is started automatically. The auto start flag must be set in
the PCON register.
7.4.3.4.3 Binary mode
This command is not fully supported in binary protocol mode.
Continuous Read in binary mode does not startup automatically at boot time, even if
the corresponding EEPROM flag is set.
Within the single shot timeout only one response is sent.
