Hi !

1 byte is 8 bits. If you want to manage bits, one by one, you can rewrite a
protocol, and replace pyserial.

Have a good day

send string data.

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.

Convert your data to numbers and use module struct to create strings out of
it.

Apart from that: You can only send chunks of bits as configured in your
serial settings - e.g. 8N1 means that you will have to send 8 Bits in a
row. I personally never used anything else, but it might be possible to
alter that setting to lets say 7N1 or even lower numeber - but I doubt that
this will work down to 1N1.

If you give us more details on your actual problem, we migh be able to give
better answers.
