SRV_RECVMSGTYPE1 Channel: 2 SNAC(4,7) 
 
  This is sent when another user, using an older client, sends you a message. 
This would seem to be a hold back from the AIM protocol as all values are big 
endian. Type 2 messages contain many little endian numbers. 
  Parameters 
Length/TLV Content (If Fixed) Designations Description 
4 xx xx xx xx TIME Seems to be a time stamp in 1/1500 sec since 8am of that Sunday. 
((time(NULL) - (8*60*60)) + DayOfWeek*60*60*24)) * 1500 
4 xx xx xx xx RANDOM A seemingly random ID generated for each message. 
2 00 01 MSGFORMAT This differentiates between messages from newer clients and older
 clients. This will be 0x0001, Type 1, for old clients. 
1 xx STRLEN Length of the following UIN in ASCII format. 
Varies xx .. UIN The sender's UIN in ASCII format. 
2 00 00 WARNING A warning level? Apparently an unused holdover from the AIM protocol. 
2 xx xx COUNT A count of the number of following TLVs. The following TLVs have been seen 
but may not always be present. 
TLV(01) 00 01 00 02 00 50 UNKNOWN Unknown 
TLV(04) 00 04 00 02 00 00 UNKNOWN Unknown, Not present in File Request, File OK, or 
Auto Message Request messages. 
TLV(06) 00 06 00 04 xx xx xx xx STATUS The sender's online status. 
TLV(0F) 00 0F 00 04 xx xx xx xx TIME Seems to be a number of seconds since a recent event. 
TLV(02) 00 02 00 04 xx xx xx xx TIME The member since time(NULL). 
TLV(03) 00 03 00 04 xx xx xx xx TIME The online since time(NULL). 
TLV(02) 00 02 xx xx MESSAGE Yes, TLV(02) again. This TLV contains the message and is 
broken down as follows: 
2 05 01 UNKNOWN Unknown 
2 xx xx BYTELEN Count of the following bytes. 
Varies .. UNKNOWN Unknown 
2 01 01 UNKNOWN Unknown 
2 xx xx MSGLEN This is the length of the actual message text plus 4. 
4 xx xx xx xx UNKNOWN Unknown. Perhaps to ensure that the length is >4, to allow you 
to distinguish between the two TLV(2) parameters? 
Varies .. MESSAGE The actual message text. There will be no ending NULL.
