TARGETID. DATASEG may be used to indicate a specific section of the data area
to be written or overwritten.

2. <DATASEG>
3. <DATALENGTH
4. <DATA>
If DATASEG and DATALENGTH are both omitted (zero length items), then all data
in the data area are to be overwritten. If only DATALENGTH is omitted or if
DATALENGTH has a value of zero, then all data within the indicated section are to
be written.
If DATASEG is omitted (zero length items), the value of DATALENGTH sets the
length of data that is to be written. If the length of the data that is to be written is
longer than the value of DATALENGTH, a communication error (CE) occurs.

This message acknowledges the success or failure of writing data to the
