9.1.2.33 WR_74_PARAM
With this function the parameter string of a slave according to profile S-7.4 is writ-
ten. Because it is possible, that the string is longer than the maibox, first it will be
written into the buffer in parts and then it will be transfered to the slave.
n is the length of the part of the string, that should be written into the buffer from
index i.
If i ≡ 0, then the string is transfered to the slave.

9.1.2.34 RD_74_PARAM
With this function the parameter string according to profile S-7.4 is read. Because
the string can be longer as the mailbox, it is written into the buffer. The content of
the buffer can read in parts from index i.
The first byte of the bufferis the length of the read string.
If i ≡ 0, then the string is read from the slave, otherwise the function responses out
of the memory, trough which the data can be read consistently.
