struct unpack newline

[grant at idscape.co.za]

Hi All,

I am pretty new to python and am having a problem
intepreting binary data using struct.unpack.
I am reading a file containing binary packed data
using open with "rb". All the values are coming through
fine when using (integer1,) = struct.unpack('l', line[86:90])
except when line[86:90] contains "carriage-return" "linefeed"
which are valid binary packed values. Error = unpack
string size dows not match format. It seems that
struct, instead of reading 4 bytes for line[86:90]
only reads 2 bytes if the second byte is CR or LF.

Thanks
Grant
