Hi all,

I have built the avr-gcc tool chain under Solaris and am able to write 
and burn simple blinking led programs to my Arduino Duemilanove board 
with avrdude and a avrispmkII SPI programmer.

I now would like to establish communication between the Duemilanove 
board and my host (Solaris 10). I could try RS232 but that would mean 
that i have to physically separate the TxD, RxD lines from the ATMEGA to 
the USB-chip and instead solder some MAX232 to the board. Since the 
Ultra 20 Workstation (Solaris 10) I am using for programmming the board 
via SPI does not even have a serial port, I am prefering to communicate 
with the board via TCP. I have the Arduino Ethernet Shield board but no 
idea how to use that. All samples I have found so far are for Arduino 
sketches. Since I am programming on the command line with pico, make, 
aavr-gcc and avrdude, I need to do this differently but how? Any example 
for that? Help (Example code, Example Makefile) would be greatly 

Thanks a lot!!!
