Re: Firecracker and USB-Serial



There is also RS232D, which specifies a pinout for RJ-45 connectors.

I just remembered a couple of things. (I guess it's true that the first
thing to go is short term whachamacallit.) System Profiler will report
details on the adapters, even without the drivers installed. You _may_ be
able to ID the chipset. And, it doesn't cause any problems to install USB
drivers w/o having the target device attached. In one case (Mini - Intel), I
installed the drivers while still hunting for my hardware. In another (iMac
- PPC), I connected the hardware and forgot I needed the drivers until
noticing no ports showed in /dev - for that, you need drivers. While your
problem seems to be that the manufacturer of your adapter failed to
implement DTR, it might be worth trying both FTDI & Prolific drivers with
your adapter on the off chance it's your driver. Can you uninstall the
current driver? (The Mac is still mostly terra incognito for me.) I'd be
concerned about it conflicting with the FTDI or Prolific driver, if not.

Anyway, I'm sure the Y-105 handles DTR and at $8 + first class postage, it's
certainly economical.
