The AppleTalk Standard

Pacer's portable AppleTalk stack, router, and AppleShare file and print services are implementations of Apple Computer's AppleTalk Phase 2 communication protocols.

Pacer's ARA server is a portable implementation of the AppleTalk Remote Access Protocol as defined by the Apple Remote Access Protocol External Reference Specification document (versions 1.0 and 2.0).
