Need to identify the designation of port COM through BACK...

I'm editting a program that sends and receives information to a device via a USB - serial adapter. Previously, the program has been run only on one pc which always use the same COM port when the device is connected. Scripts used with this program have been written to always specify this port. After having taken the device and connected to another pc, the pc allocates another COM port - this is a relatively easy task for me to go through the device management and identify the appropriate COM port, modify the script and get the device communicates with the pc. HOWEVER, in the future, communication must be maintained between the device and a laptop with any user.

The program you are using may open a windows command prompt and run DOS commands. If possible, I would like to help you find a way to use BACK to identify the COM port used by the USB adapter so I can assign this port number for a variable to be used in scripts, creating their infallible to any user.

Thanks for your time,

Chris

  • Need to identify the model A100 to select the good BIOS update

    Good morning to all and thanks in advance for any whole made :-> assitance

    My question is this:
    How to identify the exact model of a Satellite A100 PSAAxx series laptop?

    Reason:
    I need to update the BIOS and I'm uninclined to simply apply the updates, I could get for fear of turning it into a brick.

    What I know:
    There is some time, my wife and I bought a used Satellite A100 - in good working condition, but warned that he has 'problems' with USB ports driver. The time has come to address the issue of the USB, and the upgrade of the BIOS seems to be a good starting point.

    At the time of purchase, the label with the model number and the number of harem on the bottom of the system was quite readable - unfortunately, this label has subsequently lost all 'tailor-made' (we know what the fields are called by all useful information has disappeared).

    It is a Toshiba Satellite A100 (I have discs recovery and thus marked user manual).
    The user manual specifies the model number PSAAxx.
    CPU: Celeron M 1.4 GHz
    RAM: 704 MB
    HD: 40 GBbyte
    Graphics card: ATI RADEON XPRESS 200 M Series
    BIOS: v1.20 2008-12-12

    Any suggestions gratefully received

    Peter Townson :->

    Hello!

    To identify what A100 you exactly, you can use Toshiba PC Diagnostic. If you have installed the laptop with the recovery disk, this tool is installed too.

    If you n t have PC diagnosis, you can also download:

    In the diagnostic tool you can see on the part number (basic information of category).

  • Need help with the design of database

    Hello!

    I would really appreciate help in the design of my database. I have a client that has one or more provisions of a certain type. These arrangements will have accounts associated with them. A customer has access to a number of accounts (accounts have a guy too) and when the customer has an arrangement, the arrangement will tell what types of accounts are related.

    Some kind of pattern here
    http://S8.PostImage.org/qcoiozcf9/Namnl_s.PNG

    There are business rules to calculate that represents a client has access to (access above). It is basically three queries involving several different tables (you can give accounts, being a parent etc client that allows you to Auditors that you have not really own). One or two of these queries would a NOT IN / NOT EXIST (if you give your account, you won't have access to yourself until you revoke this action). AccountsOnArrangements is a subset of access (indicated by ArrangementType/AccountType-relationship). So A arrangement has all accounts of type 1, 2 and 3 customer B has access.

    My question is, basically, how I should apply access and AccountsOnArrangements.
    I can access in a view, which runs three queries with Union all. I can also use a table that I maintain with the application code. I have experimented a view but the performance doesn't look too good. I might have a materialized for each of the 3 queries that access, or view materialized for the 3 union all, but I wonder how the performance of this one will be. AccountsOnArrangements could also be a view or a table that I will maintain.

    Is it normal to use views or use the code to insert and remove rows from these tables 'close' when a base line is modified?

    Does still make sense? I have a few problems even explain :)

    In AccountsAccess will be stored CustomerId, AccountId pairs that tell the CustomerId has access to AccountId. For the entirely given accounts, there is no line for the CustomerId of the owner.

    Frequently asked questions are representing a client has access to?

    Exactly what accounts is an arrangement linked with?

    a view based on the join of the Arrangements and accounts on (CustomerId, AccountType)

  • Need to identify the model no laptop Pavilion G6

    No standard information on the case label.  Label seems to be hybrid Windows Key code also including HP codes, but no code is identified (IE without s/n, p/n prefix).

    Probably included product codes are:

    584037 001

    X 16-96072

    However, none of these codes are accepted on the HP web site.

    Can anyone help identify the correct HP product/model code?

    Hello

    Can be useful to check the alternative label tags displayed in the sub-heading "Show samples of the additional label" on the page here.

  • I need help in the design of a page with notes

    I would like to place a translation of the word one or two in a narrow column alongside a main text. There are a lot of translations in this text, about one every two lines. The function of reference simply creates a long list at the bottom of the page. This creates design challenges. Does anyone have any suggestions of what I can do to design a page where these translations of one or two words appear in one column next to the text, or somewhere other than a list of unique column at the bottom of the page.

    and iterate this code for all the lines of the vo.

    Just had my PC upgraded to Windows 7 and lost all my Firefox plugins. I had a particular SEO plugin that would show changes in the ranking for each URL in the Google search results (as a + XX, XX - or a disc orange if no change).

    Does anyone know which plugin it was? I depended on it and can find it is no longer.

    Don't worry about this issue. The answer, for someone else who wants it, is actually a plugin called SERPTrends Chrome.
