Severity values:
0 	Success (used for confirming commands), error code must be "00", and an additional flag "FC" contains the FOURCC of the command being confirmed if applicable.
1 	Recoverable (error but no disconnect)
2 	Fatal (disconnect)

Error codes:
00 	Generic, show description
x0 	Same as 00, but categorized according to the rough structure set below
10 	Generic hub error
11 	Hub full
12 	Hub disabled
20 	Generic login/access error
21 	Nick invalid
22 	Nick taken
23 	Invalid password
24 	CID taken
25 	Access denied, flag "FC" is the FOURCC of the offending command. Sent when a user is not allowed to execute a particular command
26 	Registered users only
27 	Invalid PID supplied
30 	Kicks/bans/disconnects generic
31 	Permanently banned
32 	Temporarily banned, flag "TL" is an integer specifying the number of seconds left until it expires (This is used for kick as well…).
40 	Protocol error
41 	Transfer protocol unsupported, flag "TO" the token, flag "PR" the protocol string. The client receiving a CTM or RCM should send this if it doesn't support the C-C protocol.
42 	Direct connection failed, flag "TO" the token, flag "PR" the protocol string. The client receiving a CTM or RCM should send this if it tried but couldn't connect.
43 	Required INF field missing/bad, flag "FM" specifies missing field, "FB" specifies invalid field.
44 	Invalid state, flag "FC" the FOURCC of the offending command.
45 	Required feature missing, flag "FC" specifies the FOURCC of the missing feature.
46 	Invalid IP supplied in INF, flag "I4" or "I6" specifies the correct IP.
47 	No hash support overlap in SUP between client and hub.
50 	Client-client / file transfer error
51 	File not available
52 	File part not available
53 	Slots full
54 	No hash support overlap in SUP between clients.
