string _is_ the type one would normally use in Python for 8-bit
encoded data. If you are a Unicode purist, that's perhaps
all you would use it for.

If you have a list [11, 22, 33] of bytes to send,  you can write:
buffer = [chr(i) for i in [11, 22, 33]]

Or possibly, use the struct or array module. Either way, the
problem you have to solve is converting the format you have
to/from an appropriate string. We lack the detail to suggest the
best solution to that.
