After capturing some Apache Derby traffic (which also use DRDA) there are some
unknown codepoints in wireshark.

DDM codepoint 0xc000
Parameter codepoint 0x01 (within a SQLSTT DDM)
Parameter codepoint 0xc001(within 0xc000 DDM)
Parameter codepoint 0xc002 (within 0xc000 DDM)
It seems also that wireshark sometimes does not detect parameters within a DDM,
