Just need a simple method pls

Hello, I don't want to learn the whole communications API just yet but I need a method that will send the RTS line high on a 9 pin common com port 1 say when true and off when false.
Anyone have a method lying around I can use?
Many thanks,
Phil.

Malcom,
Thanks for pointing me to the Logitech USB microphone(s). It was a week before I could get to the nearest store selling them (turns out, Radio Shack has them). Then of course, needed more time to try out the new mic. I ended up "upgrading" to the Logitech headset (ear phones & boom mic) - it works perfectly. I also find the boom mic gives much better fidelity - my voice recordings sound like I'm an announcer on NPR now.
Note to others seeking microphones for their Mac: get the USB connect type. The audio in-line on my Macs (past and present) gave "spotty performance" at best. With in-line audio connected mics, a Griffen iMic is usually needed to even get the mic to show up in "Sound" prefs. That device is merely a "USB simulator" of some kind - and I do not believe they last long enough to justify the $35 price.

  • Just need a simple client sending message to server example????

    Im trying to find a simple client-server example, where i can put the client on one laptop, server on the other and pass messages from the client to the server.

  • Just need a simple mic - suggestions

    Just got my Mac Pro 3 weeks ago so I'm getting around to lower-priority needs for it.
    My experience with external microphones includes only "cheapies" I used on my eMac. The eMac seemed "bound to not" work with mics. I bought Griffin iMic for that but it only worked a few months (seems that's pretty common occurrence for iMics). So: I threw away those mics in disgust - too bad since I coulda tried them on the Mac Pro now.
    Now - the (beautiful) monitor I bought for the Mac Pro came without built-in mic but I don't care because I "like" the advantage of being able to move the mic closer, farther, etc. Just want a mic for occassional use in recording tracks for home vids, etc. Even "semi-pro" equipment of this kind would be a waste for me.
    Oh, I plan to just use QuickTime Pro for audio recordings: worked quite well when I could manage input to the eMac.
    Any suggestions as to make / model, price, and source for "decent low-cost" microphones?
    Thanks in advance for any help.

    The problem you are describing is a known issue with Videora. The author of the software even posted that problem on their website:
    Known Bugs
    Audio/Video sync
    Problem - Output files can be out-of-sync. While no set pattern has been established, it seems to be more frequent with input files of 23.976 fps, non-DVD rips, and WMV/MPG filetypes.
    Workaround solutions - Try the custom option '-async 1'. If the disconnect gradually increases over time, setting 29.97 fps sometimes gets rid of the problem regardless of the input fps. You can also use AviSynth to assume the FPS and have the audio sync to that. If it's a sudden disconnect, check your VOB Cell settings in DVD Decrypter settings per this thread. Otherwise, test with an AviSynth script per the DaProphecy's method in the FAQ. For non-DVD files, PSPVideo 9 may be a good short-term solution until the converter stabilizes some more or try something like AviDemux
    I would suggest that you do some more research and switch to a different converter.

  • Just need some simple stats :)

    I've been using Microsoft's "Excel Lite" program for a few years. I don't even know what it's called, but its performance is more limited than Excel, which I've never used.
    I've never used a mathematical formula in a spreadsheet. All I do is insert data, which I organize an save as a CSV file, which I then import into a database table. For example, I have a spreadsheet with information on the animal kingdom, arranged by class, order, family, genus and species, all coded by cell background color/pattern and various font styles.
    To get to the point, there are two features I've grown to love that I have not found in any other spreadsheet, and I'd like to ask how Numbers compares...
    1) Sortable columns - In "Excel Lite," you can sort as many as three columns at a time. If you highlight cells spanning twelve rows, you can sort by one, two or three columns, even if you've only highlighted a single column. You can also sort an entire column (or two or three columns) by simply highlighting an entire column. I discovered that you cannot do this in OpenOffice.org's spreadsheet. I forget the details, but it was clumsy to work with.
    So how efficient is Numbers' sort feature? Can it sort three columns or just one? If I want to sort every row in a column(s), can I do so by simply highlighting the column, or do I have to specifically highlight every cell in each row and column I want to sort?
    This is the single most important feature I'm looking for.
    2) Cell/Font Attributes - OpenOffice.org's spreadsheet has a respectable number of cell background colors to choose from, but I like Excel's approach better. M$ allows you to choose various shades of each color, combine colors to create new colors and also choose background patterns, such as horizontal, vertical or diagonal lines. What scheme does Numbers use?
    Here are a few more questions...
    How many rows of data can you have in a Numbers spreadsheet? (I think my spreadsheet programs allows about 16,000, while I believe Excel allows 65,000.)
    How much text can you insert in a cell? Unfortunately, I can't use my spreadsheet program for storing articles, because each cell will only accept the equivalent of one or two medium paragraphs. I don't expect any other spreadsheet to do better...I'm just wondering if Numbers does allow you to paste entire articles into cells.
    I'm fascinated to hear that you can paste images into a Numbers document. Right now I'm organizing images I use on my websites into a spreadsheet, with separate columns for each image's ID, caption, text for the ALT tag, etc. It woul be nice if I could actually see a thumbnail of each image next to its ID and description, sort of like connecting a name with a face. Can you really do that? I would think the file size would be enormous if you were working with hundreds of images.
    I assume you can save a Numbers document as a CSV file...right? Is there also a feature that allows you to publish a spreadsheets' content directly into a MySQL database table? (I understand OpenOffice.org has such a feature, though I've never tried it.)
    Sorry for the long post. Any feedback on any particular question would be welcome. I HATE everything Microsoft, and I'm not even using Parallels on my MacBook Pro. The only M$ software program I covet is Excel, so I was elated to discover that there may be a worthy competitor out there.
    Thanks.

    Sorry, I didn't realize there was a free trial version. I just downloaded it, and my first impressions are WOW!
    The sort feature is better than the sort feature on "Excel Lite." Just click "Sort and Filter" to bring up the little Sort dialog box. At first, it looks like you can only sort a single column. But clicking the little plus sign on the right opens additional columns. I don't know what the limit is, but it's certainly far more than three.
    I also verified that you can paste very large amounts of text in a cell.
    Unlike M$'s spreadsheet, there are no cell background patterns, but there are plenty of colors to choose from. Also, it appears that there are far more options for styling text.
    I've only worked with it for a few minutes, but, for my purposes, Numbers rocks!

    The simplest way, is to erase the drive and reinstall the OS X.

    Other than that, you will have to trash all your User files, delete all the photos from within iPhoto and then empty the trash.

  • Need a convenient method to record ALL sound in- and output

    Here's what I'm going to do: I'm working for a small music magazine and I'm going to be responsible for some of the interviews from now on. As they are often done by telephone I'm planning to use Skype, as it's a cheap method to call to foreign countries.
    Now I need a simple and convenient method to record these calls for later review. I tried using 'arecord', but it takes sound from the capturing device set in 'alsamixer', which is either the microphone or the mixer (general sound output). However it has to be the microphone, otherwise I cannot talk in Skype.
    So, 'arecord' is going to record the device which is set to capture, which is the microphone, so, I'm only getting my voice recorded, but not that of the interviewee.
    It would be ok to have something that just records all audio output (independently of what's set in alsamixer) as I usually redirect the microphone to the output as well as I wouldn't hear me that well with the headset on. Commandline-tools would be prefered.

    Hi,
    Do you mean that you want all 7 dates together on 1 row?
    Here's one way:
    SELECT LISTAGG ( TO_CHAR ( SYSDATE + 1 - LEVEL
                              , 'DD-Mon-YYYY'
                    ) WITHIN GROUP (ORDER BY LEVEL)    AS txt
    FROM    dual
    CONNECT BY LEVEL <= 7
    This is an example of String Aggregation, that is, taking a column on multiple rows, and concatenating all the values (however many htere happen to be) into 1 big string column 1 row.
    Like everything else, exactly how to do it depends on your Oracle version.
    For more on String Aggregation, including differetn techniques for different versions, see http://www.oracle-base.com/articles/10g/StringAggregationTechniques.php

  • Why no simple method for reading text files

    I'd like to know, after all this time why there is no simple method of reading ext files into a string.
    Yes, yes, I know all about buffered readers, (it took me long enough to figure them out) but they are cumbersome and seem to change every release (how many file methods have been deprecated...)
    Here's what I'm looking for:
    file.open();
    file.read(String);
    file.close();
    No single character at a time, no loop - the whole file into a single string in one shot. If buffers are used, i want it hidden.
    Perl, PHP, VB, C# all have this. Even Java has it when you write to a file.
    So why not on read?
    Yes, buffered streams are very elegant, but for what most programmers want to do, they are overkill and annoying.

    Just Dennis Ritchie's little joke.
    Do you have a better reason for wanting the feature
    other than that some other languages have it?Yes. It would save me time and help dozens of new programmers who continually ask this question in this and other forums. It is in other languages because people use it and want it - clearly Jarkata saw the need. If you don't like the idea, then I won't argue the point. We agree to disagree.
    Also did you have an answer for my question?in java.io.file you can do the following: (i've used it, it works) Granted, you still have to use the buffered output streams, which in my opinion should be abstracted for a simple text read and write.
    BufferedWriter outputStream = new BufferedWriter(new FileWriter(fileNewPath));
    outputStream.write(fileContent);
    outputStream.close();

  • What's wrong with this simple method

    i'm having compile troubles with this simple method, and i think it's got to be something in my syntax.
    public String setTime()
    String timeString = new String("The time is " + getHours() + ":" + getMinutes() + ":" + getSeconds() + " " + getIsAM());
    return timeString;
    this simple method calls the get methods for hours, minutes, seconds, and isAM. the compiler tells me i need another ) right before getSeconds(), but i don't believe it. i know this is a simple one, but i could use the advice.
    thanks.

    Hi,
    I was able to compile this method , it gave no error

  • Hi I just need to know how I can upload folders of photos to icloud and send a link to clients as in Mobile Me, I'm a professional photographer so it needs to be as good as the mobile me. I've been looking at alternatives but need to be able to send links

    Hi I just need to know how to upload folders of images to iCloud and send links to clients from my iphone when on location as was simple with MobileMe. I'm a professional photographer so it needs to be as easy as it was under Mobile Me. I've looked at several alternatives but they don't seem to give the same facilities of uploading folders from the Mac then sending the link from the iphone. It seems that the iCloud does n't offer this facility so any ideas would be appreciated.
    Thanks

    Welcome to the Apple community.
    If you are doing this from your phone (as you mention) then you can use the new iPhoto Photo Journal feature to do this.
    Unfortunately, iCloud does not offer equivalents to Mobile Me’s iDisk, Gallery or Web Hosting services. You will need to find a third party solution to replace these services. You might consider DropBox, SugarSync, MediaFire or any other service that offers online storage.

  • Just need 1/8 inch to RCA for digital coax out with audigy se right?

    DJust need /8 inch to RCA for digital coax out with audigy se right? Hi there,
    I need a low profile soundcard that can deli'ver digital 5. through either coax or optical, looks like the audigy se will do just that. I have a yamaha receiver with DTS, DD, etc with a coax input that I want to use. I want to confirm that all I really need is a cable that has an /8 inch plug for the blue digital out on the soundcard with an RCA end for my receiver.... sounds simple enough to me but I want to make sure. I know I can get the digital I/O module but don't see a point if I just need the cable I mentioned.
    Thanks.

    Let's take Battlefield 242 for example. The game will not allow me to specify hardware sound.
    That would be because that card DOES NOT have any hardware on it, it is a totally software dri'ven card.
    And yes your old Li've card is much better than the Audigy SE. The Audigy SE is nothing more than a re-named SB Li've 24 bit, which is also a software based card (same applies to the X-Fi Xtreme Audio, a POS card that should have never been given the X-Fi name).
