This function defines a complete transmitter label transfer including error injection
specification to be executed on the selected API429 transmitter channel. When
executing this instruction a data buffer specified by "buf_size" is allocated within the
API429 memory. The data buffer contents may be defined with the
"Api429CmdTxXferData" command.
The allocated buffer should be released using the "Api429CmdTxXferDel"
command.
Note:
This command is not accessible if the transmitter mode 'b_Mode' in the
"Api429CmdTxIni" command is set to replay mode.
