This allows A/UX users to spool printouts to the laserwriter. If a mac user on the localtalk network wishes to login to the A/UX system using telnet he goes via the KFPS-3 onto the ethernet and into the Mac II. Question 1: Has anyone implemented a layer of software that would allow the CommCard to appear as though it were an ethernet card so that telnets to this machine would not need to go out onto the ethernet [and presumably let a MacII running A/UX to be networked without an ethernet card]. This software would encapsulate TCP/IP inside Appletalk packets as well as allowing utilities such as ifconfig to be used. Question 2: If such a layer of software were written, would it then be possible for a MAC II with both interfaces to replace the KFPS altogether, performing routing between the Localtalk and ethernet networks?
