Does anyone know where I can purchase one?Just take this one: http://www.ebay.com/itm/USB-To-RS232-TTL-PL2303HX-Auto-Converter-Module-5V-3-3V-Output-Converter-Adapter-/370812126675 US $1.67 and it is yours.But wiring that up to a "real" 9pin serial port would be a pain (doable, but a pain). Is there any devices out there with a DB-9 output connector?
You mean if you want to test full handshake with all signals - that's true. The advantage of the adapter is to get directly 5V and 3,3V. I don't know some other adapter with exactly this chip, because i don't need them. Only this Adapter which use the other chip ch341-uart which works without problems http://www.ebay.com/itm/USB-to-RS232-Serial-9-Pin-DB9-Adapter-PC-PDA-RS-232-/180399132966 When i think about it i never seen that someone uses the handshake for this simple serial communication. Not in communication with mobiles, ARM-boards or AVR microcontroller.The built-in UART's in the ARM and AVR don't suffer handshake signals, so that you must do it by software with additional IO ports.
