The module uses the error flags TIMEOUT, BUF_OV and PRM_ERR to
report errors during the parameter data exchange.
After the last parameter data has been sent to the module (MORE_PRM =
FALSE), the module checks the entire parameter set and accepts it if
everything is correct. Otherwise, the module returns a parameter error
(PRM_ERR = TRUE).
