| 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 preceeding 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 succesful 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 bogous 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. ;^) |

| Becker [& Co] provdly presents PLIP |
| |
| 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 availble 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 availble. |
| |
| 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). |
| |
| Performens |
| ========== |
| |
| PLIP easily outperforms ethernet cards....(ups, I was dreaming, but |
| it *is* getting late. EOB) |
