def run(files, wait:)
  files = files.map { |name, data, mtime| [File.basename(name.to_s), data.to_s.b, mtime || Time.now] }
  @out.emit(RZ_COMMAND)
  handshake(wait)
  files.each_with_index { |file, i| send_file(*file, files[i..]) }
  finish
rescue Cancelled, Timeout => e
  @out.emit(ABORT)
  e.is_a?(Cancelled) ? :cancelled : :timeout
rescue Hangup, IOError, SystemCallError
  :hangup
end

Sends files (as for Zmodem.send_files): writes rz and CR, waits up to wait seconds for ZRINIT, offers and streams each file, then ends the session with ZFIN. Writes the abort sequence on cancel or timeout.

Returns :ok, :cancelled, :timeout or :hangup.
