You snarl at everyone here like some junkyard dog. Why?
I have RS-232 ports on my PC's. I need them for talking to various gadgets, some of them our own designs.

If I didn't have an RS323 port, how would I hook up my Commodore 128?
If I didn't have my Commodore 128 hooked up, how would my clients see me surfing the web with CP/M on the Commodore?
Gotta keep up the old mad scientist image... :)
Hmm, strange, I just programmed a new AB rack with a Serial cable and the other day I did a DirectLogix via serial which is rather new via a serial cable. And there are also many other items in the plant we use via serial. Does that mean I'm in the stone age? I don't think so. It looks more like you are being led by those that want you to believe this, so that it cost less to produce a laptop and make you buy and adapter which does not work on every thing.
P.S. I just purchased a new Toshiba S100 S1001 just because it has a serial port on it. You maybe out of the loop here how ever, many of the high end work horse laptops also have other things. Take a look at the Panasonic Tough books. These are made for people that use a laptop for what it should be used for, not just a portable game, video and desktop office package machine.
You must be unable to read. I acknowledged such devices, idiot.
I do not, however, agree that any such device uses up 100% of windows available timeslice resources.
In other words, he's an idiot for saying it, and so are you if you believe it.
Today, it is PS3 via BlueTooth or WLAN, old man.
And yes... it IS a computer.
You may not be in the stone age, but you are blind if you missed what I said.
The PCs, rack PCs, and laptops I use at my work ARE the top of the line, and you are making yet another lame attempt at singing to the choir.
I have spec'd out more jtag and console and remote interface, etc, etc etc cables for hooking up computers to instrumentation and products in the last month than you likely ever have.
Hell, half the connectors I have to use are over $100 each. Our stuff has to survive at 70,000 feet where there is very little cooling air available for thermal management. Many of our items are conduction cooled assemblies.
P.S. We just purchased about 100 ruggedized laptops in the last month alone. All for contracted sales already on the books. Then, perhaps another twenty or more for some of our new engineers to use.
You are out of ALL of my loops, you loopy twit.
0xc0000034 is a win32 exception code, meaning something failed to initialize. At a really wild guess I would think that perhaps qwave.dll is missing from your c:\\windows\\system32.dll.
Blah, Blah, Blah.. Join the industrial world! You're playing with toys.
Jesus. If all you do is use your equipment as calculators I guess you wouldn't need a real mans tool. Have you ever been told that you come up short?
Not that it has any relevance how ever, I have been hearing stories from our IT department on how Vista seems to make some things disappear after updates. And the items apparently are random.
We have very few PC's in house that actually have Vista now, IT, has been down grading those that had Vista to XP pro.
I guess the problem isn't so much of lack of speed where they were being used, they seem to exhibit random unwanted behavior in some of our logging and database applications where data isn't fully log ect. Peach Tree database seems to ring a bell as one of the troubled areas on Vista which is suppose to be Vista ready..
Micro$uck makes garbage...
You're an idiot. Our gear tracks satellites at 30ips slew rates on moving machinery/equipment/plane/trains/cars/ships/etc.
From VME to PC, the controlling equipment doesn't matter, idiot. This is a COTS realm, and you are behind all of the curves we create.
Let's see... HAIPE level IP encryption, satellite tracking, multi-stream/multi-bus specification data management...
Yep... mostly calculations... very fast, very complex calculations. aAlong with a lot of data handling.
In case you forgot, that is what a computer does, idiot.
I don't. My nine inch tool qualifies as a real man's tool all day long.
Have you ever been told that you are guessing, little boy?
snipped retarded little boy spam link.
Being the idiot that you are, I would say that you are so stupid, you are likely trying to install it on mass purchased, bare bones, 5 year old junk that barely runs XP, much less anything more powerful.
I STILL contend that dopes, even those that claim to be in IT departments, that have problems with Vista, are dopes that create their own operator error level faults, and are too stupid to see that it is their own inept lack of capability that keeps them from getting anywhere.
Peach Tree, is so lame, they still think they are running as an underlying DOS based app. I have seen a lot of "accounting" packages and MRP packages that are so damned old when they were first authored that the LAZY company that started them are to cheap to actually do a REAL Windows compliant re-write, which is what they need. So sure, a modern OS might puke a little bit on keeping a barely compliant, non-modernized app from running all the time correctly.
Even the screen forms they present are old ASCII looking DOS app looking stupidity. I could always tell when a company was a money grubbing bunch of jerks, and when they had a REAL product.
Hire a REAL database guru, and PORT your stupid accounting mistake choice to a REAL database. Stop blaming everything OLD on something NEW.
Mine works fine. Even plays both HD DVD and BluRay movies, data discs, etc.
Today's update included new Nvidia drivers, yet it was MS that offered the updates... Imagine that, just like Linux... single point source updating.
Since starting with a beta that MS offered me nearly 4 years ago, I have yet to have a problem.
My box works fine, and has a 4 year old MOBO, a 6 year old sound card, and a two year old video card. Just watch both an HD DVD flic and a BluRay flic to verify that my SATA multi-reader/writer works. It does.
It can also burn a DVD at 16x, which is 22MB per second constant stream. Not bad considering that my first PC based DVD player had it's own decoder board and was over $400, and was only 1X.
I think you children cry too much, and destiny whops you right upside da haed with your own stupidity.
Did I say I was in the IT department? That goes to show just how well you actually pay attention.
I'm fully confident that our IT techs can blow smoke around you any day.
Oh give me a break!...
Just for you. " SOME PEOPLE ARE LIKE SLINKIES. NOT REALLY GOOD FOR ANYTHING BUT THEY BRING A SMILE TO YOUR FACE WHEN PUSHED DOWN THE STAIRS. "

rI use RS-232 for lots of things too. Some of them are also of my own design. RS-232 has the advantage that it can run through 1000 feet of twisted pair without troubles.
I also use the LPT port to do some things. One thing that is handy is to program CPLDs that can program via the JTAG port. With 4 resistors and some connectors, I can build a new programming cable to work with the PCB that has the JTAG connector wired differently.

I think you need to go back and reread what I wrote very carefully. If you still don't get it reread it again. If after rereading it four or 5 times you still don't understand, just go kill yourself.
Not true. The cable is very specific as to the twists per inch, etc. Also, twisted pair is not even needed if the entire cable is shielded, and has a low enough interconductor capacitance. That includes backshells and drain wires properly terminated.
From the trusted wikipedia source:
quote:
The standard does not define a maximum cable length but instead defines the maximum capacitance that a compliant drive circuit must tolerate. A widely-used rule-of-thumb indicates that cables more than 50 feet (15 metres) long will have too much capacitance, unless special cables are used.
By using low-capacitance cables, full speed communication can be maintained over larger distances up to about 1,000 feet.[5] For longer distances, other signal standards are better suited to maintain high speed.
end quote
As you can see, your statement is likely only true with the oldest, slowest data rates, and the heaviest drive circuitry. Things that are not likely even still available.
Are data rates below 9600 even selectable these days? Do you think the drive chips are still as powerful as they were then? I mean... I know what the word compliance means, but I have also seen a lot of fudging over the years.
Yes true. It works very nicely for distances greater than that.
Twisted cable works better than non-twisted shielded. The distance that RS-232 will work over is shorter every shielded cable I've tried. At those sorts of lengths, the losses other than capacitance start to matter.
You show your ignorance with that statement.
The standard does not specify what circuit be used for a driver. It certainly doesn't say that an IC must be used. If I needed to I could use transistors. I don't need to because plenty strong drivers can be had.
More ignorance? I can still set to 75 Baud if I want to.
If I want, the drivers can be stronger. But yes you can get good drivers.
I also know what compliance means that is why I stopped at 1000 feet. It will work far farther but you would not be in complete compliance then.
It depends entirely on the environment one wants to place the run in. Trying to cross even a mere 200 feet of shop floor, hung up in the same place as the power runs, is not the place for UTP.
