Yes, but I think it should work with individual input bytes, I noticed that it's not checking the buffer for overflow in that case, so I will fix that today. I was getting crashes by feeding [slipdec] with random bytes.

Maybe it's a [print] object overloading? Trying to print thousands of numbers usually hangs Pd.

It should be able to hold on to a partial message indefinitely, but at the moment if the message list isn't a complete SLIP packet it might not work properly.
