I want to display a progress bar showing what proportion of a lump of data has been received via a stream created using COMM:OPEN-TCP-STREAM. I can arrange to be sent the size of the data before it is sent, but is there a way to find how much data has been received at a given time? (I want something like CL:FILE-POSITION, which, as far as I can see, always returns NIL for TCP streams.) Simon Katz
