Hi Daniel, Yes you should be able to use the FT232R as if it was a normal serial port.
I use the Sparkfun FTDI breakout board (which has a FT232RL) as a bitbang programmer for the ATtiny25 series, the ATmega328P, as well as the ATtiny10 because I do not have a "real" programmer. I (randomly) picked the "dasa" configuration, which utilizes the following signals: RTS, DTR, TXD and CTS. Hope this helps. -- Regards, Darell Tan On Sun, Nov 4, 2012 at 5:17 PM, "Ing.
