ILS::Patron is where most of the intelligence for SIP's representation
is lodged. Currently there is difficulty with C4::Members functions.
GetMemberDetails is required for the needed flags, but it returns
empty structure on bad barcodes, where it should be undef.

The basic problem is that the SIP logic doesn't know where the
input is coming from. It might be a RAW socket, and it might
be telnet. If it is telnet, although the specs declare a
character set (from MS, unfortunately), they do not specify a telnet
implementation. So you might get telnet handshaking or
renegotiations in the middle of an otherwise peaceful session and
these should not be taken as SIP commands. Patches include a move
towards using $CRLF from Socket to avoid problems w/ foreign platform
mapping \n and \r to \015 or \012.
