I've just been playing around with the LPFK again.
In loopback mode, it seems to actively send data out of the 8051's serial
port, then loop it back through. I've caught it sending data at 9600 Baud,
apparently 8 bit data with a parity bit:
Keys numbered left to right, top to bottom:
Key Binary data
#11 S_0101_0000_1
#14 S_1011_0000_0
Format: StartBit_D0-D3_D4-D7_Parity
It appears that keys are numbered from zero, odd parity.
Of course this doesn't really help with the "active" mode. I suspect the
loopback switch is being used to toggle a GPIO, and redirect TXD to RXD somewhere.
In "active" mode, sending a serial BREAK causes the LPFK to reset itself.
Sending "SFFFFFFFF" followed by an LF causes the LEDs to blink once, then shut
off.
I don't think there's much that can be done with the LPFK without desoldering
the 8051 chip and reading out the program. Catch is, the chip has probably had
its encryption table programmed, and probably the lock bits as well...

OK. Can I bring up politics and religion, too? As long as I am nice
and say "OT"? I am sure Jay would not mind.

I am already headed to the bathroom so I can put a bar of soap in my mouth.

I'll go with Marden here. The subject line is like a table of contents, and if I
am looking for something, it is just unacceptable to have the table of contents
have no relationship to the books contents.
For some unknown reason, some posters seem to think it is perfectly okay here to
waste the time of other readers here.

You'd be banned already.

Hi,
I have a couple of these SparcPrinters, that I haven't touched since I
got them. Figured I'd offer them to someone who might want them. Not
sure of the demand for these things, and not sure if they work at the
moment, but there's no reason they shouldn't. I also have the cables
for them. Pickup in the Chicagoland areas or willing to ship if you pay
the actual costs.

Funniest, is that "feature" makes it unusable at, oh, 9 out of 10 universities in this country, and countless
numbers of businesses. I know I couldn't use it at work - it wouldn't open hardly anything.
I'd me MORE than happy to install OpenOffice on my wife's laptop...
But what is she to do when the send her stuff in Office 2007 format, which OO can't open?
Don't get me wrong - I'm not pro Microsoft, or anything. This is just a tool that my wife needs in school,
and it was cheap. Obviously, by installing OO 2.4.1 and trying to open some of her docs from her last
semester, OO isn't going to cut it. It opened 3 out of 17,and the rest, it wanted me to go through a HUGE list of formats to choose one,of which most Office 2007 stuff was missing. Office jsut knows what it is.
Couldn't even open the PowerPoint presentations at all.

Funny, but it's still not fully Office 2007 compatible.
Had trouble with Word 2007 templates and certain docs, and can't open PowerPoint 2007 presentations.
I JUST tried 2.4.1 from openoffice.org with some of my wife's school .doc's and PPoint presentations.
Guess THAT didn't work out like you planned.
Has anyone here dealt with the fans on a VAXstation 4000/vlc? I use
one as a DECnet router, and its fans are "howling" loud enough that
it is not "dining room friendly" (believe it or not I'm the one that
says it's to loud to run and not my wife). I'd prefer to keep the
/vlc running rather than replace it with either a /60 or /90.

Not to be a jerk about it, but welcome to the Internet. People swear,
just like they do in real life. If your mom doesn't want you to hear
those words, set up an email filter or something. Hell, he even
censored himself, but you still felt the need to complain?
I do agree that this topic is just fine on the list; it's not like we
have these sort of threads every day, and some people could find this
information (about the Academic Alliance and other things) useful.
