Hardware flow control (RTS/CTS) is enabled, but your serial adapter doesn't support it. Solution: Turn off flow control (DIP switch 6 to OFF). Or use a null modem adapter with loopback pins 4-5 and 6-20.

Access setup mode: Press Setup key (if present) or Ctrl + Shift + Setup or F1 during power-on.
