tpktHeader (4 bytes): A TPKT Header, as specified in [T123] section 8.
x224Data (3 bytes): An X.224 Class 0 Data TPDU, as specified in [X224] section 13.7.
mcsSDin (variable): Variable-length PER-encoded MCS Domain PDU (DomainMCSPDU) which encapsulates an MCS Send Data Indication structure (SDin, choice 26 from DomainMCSPDU), as specified in [T125] section 11.33 (the ASN.1 structure definitions are given in [T125] section 7, parts 7 and 10). The userData field of the MCS Send Data Indication contains a Security Header and a Set Keyboard IME Status PDU Data (section 2.2.8.2.2.1) structure.
securityHeader (variable): Optional security header. The presence and format of the security header depends on the Encryption Level and Encryption Method selected by the server (sections 5.3.2 and 2.2.1.4.3). If the Encryption Level selected by the server is greater than ENCRYPTION_LEVEL_NONE (0) and the Encryption Method selected by the server is greater than ENCRYPTION_METHOD_NONE (0) then this field MUST contain one of the following headers:
Basic Security Header (section 2.2.8.1.1.2.1) if the Encryption Level selected by the server is ENCRYPTION_LEVEL_LOW (1).
Non-FIPS Security Header (section 2.2.8.1.1.2.2) if the Encryption Method selected by the server is ENCRYPTION_METHOD_40BIT (0x00000001), ENCRYPTION_METHOD_56BIT (0x00000008), or ENCRYPTION_METHOD_128BIT (0x00000002).
FIPS Security Header (section 2.2.8.1.1.2.3) if the Encryption Method selected by the server is ENCRYPTION_METHOD_FIPS (0x00000010).
-
If the Encryption Level selected by the server is ENCRYPTION_LEVEL_NONE (0) and the Encryption Method selected by the server is ENCRYPTION_METHOD_NONE (0), then this header MUST NOT be included in the PDU.
setKeyBdImeStatusPduData (28 bytes): The actual contents of the Set Keyboard IME Status PDU, as specified in section 2.2.8.2.2.1.
