[PD] tcpip binary into pd

Ok, I see. I don't know the [netclient] object, but TCP networking 
objects like [netreceive -b] or [iemnet/tcpreceive] all output a stream 
of bytes. In your case, just collect the bytes into a list until you hit 
byte 13 (CR), then you can split the resulting list by byte 59 (";"). 
Now you need to convert each sublist to a proper Pd message:

Ideally, you know in advance which type you expect for each item. If you 
need an item as a Pd symbol, you can send the (sub)list to [list 
tosymbol], which will output a single Pd symbol - even if the string 
contains whitespace! If the item is numeric, you can pass it to 
[fudiparse], which wil output a Pd float.

Otherwise, you can just pass the (sub)list to [fudiparse] 
unconditionally, but a string like "Affectiva AFFDEX Landmarks" will 
yield a Pd message with 3 symbols, because whitespace is the delimiter 
for Pd message atoms. You can catch this with [list length]: if the 
resulting Pd list has more than 1 item, this means that a string 
originally contained whitespace and you can concatenate the symbols (if 

In your case, you can actually just pass the *whole* message to 
[fudiparse] and it will automatically split it into invididual Pd 
messages (because ";" happens to be the FUDI message delimiter), but 
watch out for the problem with whitespace in strings as described above.

Hope this helps!
