SPC3 evaluates the first seven data bytes (without user prm data), or the first
eight data bytes (with user prm data). The first seven bytes are specified
according to the standard. The eighth byte is used for SPC3-specific
communications. The additional bytes are available to the application.

That is, stop bit monitoring is not
switched off.
WD_Base = 0
That is, the time base is 10 ms.
