I didn't think getchar/putchar existed in the Atmel libc implementation.. I would suggest using a different function name and implement it differently for either platform. Also you'll want to be careful about the fact that the Atmel has 2 separate address spaces (if it's an AVR anyway) which can cause problems because you have to read from the right one. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
