This article is from the AmiTCP/IP FAQ, by Mike Meyer with numerous contributions by others.
SANA-II is the software interface between AmiTCP and your network interface. There are freely available SANA-II drivers for SLIP. CSLIP, the A2060 card and the A2065 card and PPP. If you are purchasing a card to connect your Amiga to a network such as Ethernet, make sure that the card has a SANA-II driver if you want to use AmiTCP with the card.
The SANA-II is the standard Amiga network device driver specification released by Commodore-Amiga. The SANA-II specification is available on the Aminet, fish disks and other forums. (Thanks Jarno)
