What I meant is that you can find some of these modules on eBay where they have been modified with the series cap on the correct line. Those ones will do the auto reset of the ATMega without the need to add the series cap on the board itself.
I am not aware of a USB to TTL module - on eBay at least - which has been modified especially to incorporate a series capacitor for use only with breadboarded ATMegas, making it non-standard as an RS-232 interface.I understand some have now been made with the corrected wiring and a pinout to match the FTDI module which does not contain such a capacitor in order that they do suit the Pro Mini and other ready-made boards all of which have the capacitor on the MCU board itself.
Can you point me to an example of such?
Must say that the use of all those italics and stating you are not aware, does make it come across as a little condescending; i.e. you're not aware, therefore I'm making something up.

Jeesh, you are hard to convince!
Yes, it has been modified to include the 0.1uF cap to provide a direct AVR reset pulse on a pin from the module. As it clearly states, it will work with 'barebones' set ups without the need to do the manual reset.
Am I to therefore to gather (since the opposite side of the board is not revealed) that he has modified these by cutting the track to the reset pin on the CP2102 and wired this extra capacitor on the back of the board between DTR and the "RST" pinout?
