running netbsd-current and using rzsz-9204. can receive files just fine
with "rz", but when attempting to upload a file to a remote host using "sz"
i get "awaiting pathname nak for <filename>" and it just sits there until
i kill -TERM on the sz process.  is there some magic set of flags i have to
give "sz" to make it work? i'm using "minicom" as a terminal emulator.
