Does the AXE027 USB to serial cable employ any handshaking flow control?
My question comes from the fact that the AXE027 schematic diagram shows the FTDI FT232RQ chip with pins 8 and 32 tied together.
This connects RTS (request to send) to CTS (clear to send) and would suggest flow control handshaking.
However, I have constructed and tested this circuit and it works properly with RTS and CTS tied together or left unconnected, indicating that flow control is not implemented.
A little light on this matter is much appreciated.
Thank you in advance for a reply.
