Tested three different IDE versions under an XP VM environment.1.0.6
1.56.5-r2
1.6.9
wow, thanks - i really appreciate your comprehensive checking !
avr_fred:
with an identical to yours CH340G board
sorry to be doubtful, but given the multitude of varieties of those things on eBay, can you be quite sure ?

...and a ProMini with the Uno bootloader installed. This was loaded by selecting the Uno board tye and then burn booloader in the IDE. Connections are:CH340G ProMini
DTR <----> DTR
RXD <----> TXD
TXD <----> RXD
VCC <----> VCC
CTS
GND <----> GND
All three versions yield the same results: Board type: Uno - Uploads and runs Board type: Duemilanove w/328P - Uploads and runs Board type: ProMini 5V w/328P - Uploads and runs
the common factor being the ProMini - i wonder whether these CH340G boards are tailored to cater for the ProMini boards that also proliferate on eBay.

Based on the above, I would suspect that either you don't have a Uno bootloader installed or the fuses are set incorrectly on the target device.
that 'saga' i mentioned above documents in detail that this should NOT be the case !
as it stands now, i have the original 328P chip on the breadboard, with a sketch loaded WHILE ON the Uno board (normal upload, meaning HAS the bootloader) and runs the sketch (blinking LED on every digital pin in sequence) running on external power source - ie. standalone success.
it really is the USB-to-TTL converter that is not playing nice with this setup i have atm.
