The character format is the same as for the input data transfer
frames include an SOF, data, a CRC and an EOF (as shown in
data transfer, in case of error, the reader does not emit any error code to the SR176, but
must be able to detect and manage this situation. The data transfer rate is 106 Kbit/second.

The EOF, as shown in
