Why has no one ever attempted to do anything with XT? XT is not really much use for something like DNET because it only gives 8 virtual connections. Since that would be a silly limitation to put into DNET, it would still need its whole link protocol support anyway, so it's better to just do it over the raw serial line. Actually, I don't know what DNET uses sockets for, but I doubt that it's for the tty port multiplexing. >2) Write a 630 emulator for the Amiga, and let layers be the host end of the >program.

This would be Truely Awesome, and has been on my "todo" list of Amiga hacks for a long time. Perhaps I can get some official blessing to dedicate some time to it now that Commodore is about to start selling a system with standard XT support (Amix has all the XT drivers and the "layers" program, etc.). Right now, an A2500UX with seven A500's hanging off it is pretty neat, but it would be much better if they could each have several Unix windows instead of just one. I'm pretty sure the info from AT&T can be had, but I think it might introduce some licensing problems (I wouldn't want said 630 emulator to be derived from AT&T code and therefore require a license fee to AT&T -- I'd rather build it just from available information.) Yes, it wouldn't be as general as DNET, but the host end is already written and standard with any recent SysV system. -- -=] Ford [=- "The number of Unix installations (In Real Life: Mike Ditto) has grown to 10, with more expected." ford@kenobi.cts.com - The Unix Programmer's Manual, ...!sdcsvax!crash!kenobi!ford 2nd Edition, June, 1972. ditto@cbmvax.commodore.com
