Hello Greg,
have you buyed one of this jinxed PL-2303 HX adapters?
No, I have not been able to find one. 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.
thanks,
