->Actually, I've noticed that on every Unix system I've used ftp on, the
->number of hash marks is never quite the same, even for the same file.
->And the number of hash marks is always at least as many as there
->should be, but usually more.  For example, transferring an 80K file,
->you might get 93 hash marks one time, and 107 another. My
->interpretation of why this happens is that in the code, it does a
->read(fd,buf,1024) to read 1K, printing a hash mark for that 1K, but
->not taking into account (as far as printing hash marks goes) that the
->read call may return less than 1024 bytes read. So you end up with
->extra reads, and therefore an inappropriate number of hash marks
->printed. I believe it has the same problem with writes, also. (Haven't
->watched carefully; I usually do "ftp" get commands so the umask value
->will take effect.) JTYMLTK.

Another possibility is that some packets were bad so they had to be
retransmitted again :^).
