    _______________________________________________________

Details:

This patch adds new commands to avrdude's terminal mode to support direct SPI

transfers.

Two commands are added:

spi
  This command sets RESET# to inactive state allowing AVR to run.

pgm
  This command returns AVR into programming mode

After `spi' command is given, `send' command sends up to 4 bytes to SPI. LED

pin, if present, acts as SS# (slave select) signal. It is set to 0 (active) 
before bytes are transmitted, and returns to 1 (inactive) after all bytes 
sent. In this mode, `send' command is allowed to use with less than 4 
arguments.


This patch was contributed by Andrew O. Shadoura and submitted via the Debian
bug tracking system: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=509130
