- Hi again
-
- About my previous mail: I've looked into parallel.asm, and I'm
- rather confused. Looks like the code agrees with you, but not
- the protocol description preceding it?? I got to look more
- careful, but it wont be for a while (approx a week).

- >make one yourself. The wiring is:
- > INIT 16 - 16 SLCTIN 17 - 17
- > GROUND 25 - 25
- > D0->ERROR 2 - 15 15 - 2
-
- I saw you removed 1 and 14 from the cable description, but not
- 16 and 17. Why is that?
-
- Have been successful in getting parallel.com working (the Messy-Loss
- software). Using the pksend on the sender and pkall/pkwatch/whatnot
- gives me a hung receiver. (The cable works, I've tried unet11, a DOS
- cheap-net prog.)
-
- Using PLIP v0.03 and trying to ping the other end gives
- 88 timeout 88 timeout....(more) 2386 bogus packet size, dropped
- on the receiver, and on the sender lots of timeout, but of
- course I don't know how much is supposed to work.
-
- The following to something I wrote when I should have gone to bed a
- long time ago. Use it for whatever you like, or dump it in the bin. ;^)

-
- What is PLIP?
- =============
-
- PLIP is Parallel Line IP, that is, the transportation of IP packages
- over a parallel port. In the case of a PC, the obvious choice is the
- printer port. PLIP is a non-standard, but [can use] uses the standard
- LapLink null-printer cable [can also work in turbo mode, with a PLIP
- cable]. [The protocol used to pack IP packages, is a simple one
- initiated by Crynwr.]
-
- Advantages of PLIP
- ==================
-
- It's cheap, it's available everywhere, and it's easy.
-
- The PLIP cable is all that's needed to connect two Linux boxes, and it
- can be build for very bucks.
-
- Connecting two Linux boxes takes only a seconds decision and a few
- minutes work, no need to search for a [supported] netcard. This might
- even be especially important in the case of notebooks, where netcard
- are not easily available.
-
- Not requiring a netcard also means that apart from connecting the
- cables, everything else is software configuration [which in principle
- could be made very easy.]
-
- Disadvantages of PLIP
- =====================
-
- Doesn't work over a modem, like SLIP and PPP. Limited range, 15 m.
- Can only be used to connect three (?) Linux boxes. Doesn't connect to
- an exiting ethernet. Isn't standard (not even de facto standard, like
- SLIP).
-
- Performance
- ==========
-
- PLIP easily outperforms ethernet cards....(ups, I was dreaming, but
- it *is* getting late. EOB)
