- Etherslip is an adaptation by Paul Martineau of the old SLIP8250
- Packet Driver and it attempts to provide an Ethernet interface to applications.
- It creates a fake Ethernet hardware address and it fakes ARP packets. Because
- it is based on the old item it probably locks up some machines (loss of serial
- port interrupts, a design issue solved below).
- SLIP8250 is a regular SLIP Packet Driver and presents a SLIP interface
- to applications. Thus the apps need to understand SLIP. I rewrote SLIP8250,
- and that's what you probably have (Crynwr, edition 10). I also rewrote parts
- of Etherslip and gave the material back to Paul, but I've heard nothing on
- it for almost a year now. Questions and comments on Etherslip should be sent
- to him.
- SLIP8250 does NOT do VJ header compression, as a glance at the source
- file will verify.
- CUTCP understands SLIP, as does MS-DOS Kermit v3.12, but NCSA Telnet
- does not (at least the version I have here), nor do many other DIX Ethernet-only
- programs. And so far Kermit is the only pgm to also use ODI directly (no shim),
- so a large number of media are available: Ethernet(s), Token Ring(s), Arcnet,
- etc. That means Kermit can use PPP when that ODI driver becomes available to
- the public.
- To repeat an old song: please fellas (developers), let's get ODI
- support into these programs. All the docs are available, from netlab2.usu.edu
- as well as from Novell's machines.
