I didn't think getchar/putchar existed in the Atmel libc implementation.. I would suggest using a different function name and implement it differentl= y=20 for either platform. Also you'll want to be careful about the fact that the Atmel has 2 separate= =20 address spaces (if it's an AVR anyway) which can cause problems because you= =20 have to read from the right one. =2D-=20 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 --nextPart3373236.7uS1DI0nbt Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQBCHV/55ZPcIHs/zowRAlTqAJ9zJZHr2OAlgTNG06Y5MDBeNj+F4QCeOrEC WuRsKRbVVQRwD74rVFMUcx4= =emgK -----END PGP SIGNATURE----- --nextPart3373236.7uS1DI0nbt--
