One of the handier gadgets I've picked up over the years is one of those little gizmos that has a male-female pair of DB25 connectors on it and a set of LEDs (five? seven? I forget...) I can't recall where I got it, some mail-order outfit, but last time I looked radio shack was selling those, too. It appears to be the identical unit. In fact, it's in the handy catalog here for $14.99 as 276-1401. Only about double what I paid for mine. Lacking that, you can probe the pins with a bidirectional LED/resistor combo, the other end of things grounded. Or a pair of back-to-back LEDs, only one resistor needed. No light means that you're either looking at a pin that's not connected or an input, a light tells you that you're looking at an output, and those signals on which pins will tell you how the port is wired. My usual thing with the gizmo was plug it in, see which lights came on, then plug it in to the other half of the hookup and see if the _other_ lights came on, which was a good sign. If the same ones came on both sides, that was usually a pretty good indication that some crossover wiring was needed.

Gotta get the bottom-level hardware stuff right first, doncha think? ---* Origin: TANSTAAFL BBS 717-838-8539 (1:270/615) SEEN-BY: 633/267 270 @PATH: 270/615 150/220 379/1 106/1 2000 633/267 |
