Standard data
transfer
The data is transferred character by character. The number of data
bits, stop bits, the handshake and character parity must be set by
the user.
Blockwise data
transfer
The data is transferred blockwise. For data backup, a so-called
block check character (BCC) is used. This method improves data
security.
