I have an ATtiny 13 programmable microprocessor. I wanted to use avrdude, the ATtiny13 and my ft232r chip. To do this,

      ------
 RTS-|ATtiny|-GND
 RXD-|  13  |-
 TXD-|      |-
 VCC-|     o|-DTR
      ------
  • I connected the FTDI chip with the computer
  • I unloaded the ftdi driver:
rmmod ftdi_sio
  • I told avrdude to output the first byte
tweedleburg:~/at/avrdude-5.10 # ./avrdude -cft232r -pt13 -P/dev/ttyUSB0 -U hfuse:r:-:h -B 1
avrdude: BitBang OK 
avrdude: pin assign miso 1 sck 0 mosi 2 reset 4
avrdude: drain OK 

ft245r:  bitclk 4800 -> ft baud 2400
avrdude: AVR device initialized and ready to accept instructions

avrdude: Device signature = 0x1e9007
avrdude: current erase-rewrite cycle count is -158 (if being tracked)
avrdude: reading hfuse memory:

avrdude: writing output file "<stdout>"
0xeb

avrdude: safemode: Fuses OK

avrdude done.  Thank you.

Which is basically what I expected.
