USB to (DB9) Serial Adapter and Minicom - help needed

I'm having problems with my Netgear DM111P ethernet modem.
I bought it off ebay and it was 'bricked' on arrival .
All of the LEDs are flashing okay except for a solid red one which should be solid green.
I would like to reflash the firmware. However, I've never done this before and I'm learning as I go.
I've only just started the process and so far it hasn't been that successful.
Basically, I don't know what to do.
Since my IBM Thinkpad T40 doesn't have a serial port, I bought a USB to Serial adapter.
When I plug it into a spare USB port, dmesg reports:
usb 2-2: new full speed USB device using uhci_hcd and address 2
usb 2-2: configuration #1 chosen from 1 choice
usbcore: registered new interface driver usbserial
drivers/usb/serial/usb-serial.c: USB Serial support registered for generic
usbcore: registered new interface driver usbserial_generic
drivers/usb/serial/usb-serial.c: USB Serial Driver core
drivers/usb/serial/usb-serial.c: USB Serial support registered for pl2303
pl2303 2-2:1.0: pl2303 converter detected
usb 2-2: pl2303 converter now attached to ttyUSB0
usbcore: registered new interface driver pl2303
drivers/usb/serial/pl2303.c: Prolific PL2303 USB to serial adaptor driver
and lsmod shows the pl2303 kernel module has loaded:
n00b ~ $ lsmod
Module Size Used by
pl2303 19076 0
usbserial 30696 1 pl2303
So, if I understand things correctly, the USB to Serial adapter has been recognised by the kernel and the driver loaded. dmesg also reports:
n00b ~ $ dmesg | grep tty
console [tty0] enabled
00:0a: ttyS0 at I/O 0x3f8 (irq = 4) is a NS16550A
usb 2-2: pl2303 converter now attached to ttyUSB0
which suggests I should configure minicom (# minicom -s) with /dev/ttyUSB0 rather than /dev/ttyS0. However - and this is where I'm out of my depth with minicom - when I invoke minicom it comes up with a dialog saying "Initializing Modem". I don't want to use a modem. I want to see what the CFE bootloader of my DM111P is outputing so that I can see what's wrong with it.
Can anyone help me out with this please? I've never done any serial port work before.

Thanks for the reply Rasika but I already tried that cable. Checked it out with an Ohm meter, cable was pinned correctly. It worked on a 4402 controller but not the 2006. I did try all kinds of serial settings and usually you get some garbage displayed if the baud rate, parity, stop bits, etc... are wrong but this had nothing displayed. I suppose it's possible that both 2006 controllers are bad but the odds are extremely small hence I still suspect the cable. Do you know of an actual Cisco document that shows the console cable pin-out for the 2006? If I had an actual Cisco document and not a user supplied document and that cable didn't work, then I guess there recycling material. Any other idea's or thoughts? Thanks!

Lenovo X131e doesn't work with Prolific PL2303 based USB to Serial Adapter and Windows 7 x64

This is sort of a bug report. A Lenovo X131e with Windows 7 x64 and the PL2303 driver including 1.6, 1.61 and 1.7 will not successfully install the driver - Windows always reports "Driver Install Failed" on plug in to USB 3 or USB2 ports. However, putting a USB2.0 hub inbetween the USB to Serial Adapter and either USB port type makes the adapter work fine. This was not the case with the X130e. I'm not sure where to report this beyond this posting, but more of an FYI.

If the USB can be used for other equipment,
That may be compatibility issues for USB and Prolific PL2303.
Don't plug Serial Adapter when installing the driver,
Ofter installation, Connect serial adapter to see whether it is working normally.

I just moved to Germany, I want to know if an adapter and converter is needed to charge my iPod, iPhone and MacBook Air is needed or can I simply use an adapter? Will the voltage automatically change?

I am having a really hard time with keeping my charger on the adapter/converter that I bought for my trip but I also bought an adapter and with that my charger doen't fall and my apple products would be able to charge withought me having to hold the charger in place. I want to know if the converter is needed or if I only need the adapter. I do not want to blowout my iPhone, iPod or my MacBook Air.

All that is requried is an inexpensive plug adapter. Apple's power adapters themselves will work with any utility power on Earth. Non-Apple power adapters may not.
I don't understand what you mean by having to hold the charger in place though.

[Mostly Sorted] Extracting tags - regexp_substr and count help needed!

My original query got sorted, but additional regexp_substr and count help is required further on down!
Hi,
I have a table on a 10.2.0.3 database which contains a clob field (sql_stmt), with contents that look something like:
SELECT <COB_DATE>, col2, .... coln
FROM   tab1, tab2, ...., tabn
WHERE tab1.run_id = <RUNID>
AND    tab2.other_col = '<OTHER TAG>'(That's a highly simplified sql_stmt example, of course - if they were all that small we'd not be needing a clob field!).
I wanted to extract all the tags from the sql_stmt field for a given row, so I can get my (well not "mine" - I'd never have designed something like this, but hey, it works, sorta, and I'm improving it as and where I can!) pl/sql to replace the tags with the correct values. A tag is anything that's in triangular brackets (eg. <RUNID> from the above example)
So, I did this:
SELECT     SUBSTR (sql_stmt,
                   INSTR (sql_stmt, '<', 1, LEVEL),
                   INSTR (substr(sql_stmt, INSTR (sql_stmt, '<', 1, LEVEL)), '>', 1, 1)
                   ) tag
FROM       export_jobs
WHERE      exp_id = p_exp_id
CONNECT BY LEVEL <= (LENGTH (sql_stmt) - LENGTH (REPLACE (sql_stmt, '<')))Which I thought would be fine (having tested it on a text column). However, it runs very poorly against a clob column, for some reason (probably doesn't like the substr, instr, etc on the clob, at a guess) - the waits show "direct path read".
When I cast the sql_stmt as a varchar2 like so:
with my_tab as (select cast(substr(sql_stmt, instr(sql_stmt, '<', 1), instr(sql_stmt, '>', -1) - instr(sql_stmt, '<', 1) + 1) as varchar2(4000)) sql_stmt
                from export_jobs
                WHERE      exp_id = p_exp_id)
SELECT     SUBSTR (sql_stmt,
                   INSTR (sql_stmt, '<', 1, LEVEL),
                   INSTR (substr(sql_stmt, INSTR (sql_stmt, '<', 1, LEVEL)), '>', 1, 1)
                   ) tag
FROM       my_tab
CONNECT BY LEVEL <= (LENGTH (sql_stmt) - LENGTH (REPLACE (sql_stmt, '<')))it runs blisteringly fast in comparison, except when the substr'd sql_stmt is over 4000 chars, of course! Using dbms_lob instr and substr etc doesn't help either.
So, I thought maybe I could find an xml related method, and from this link:get xml node name in loop , I tried:
select t.column_value.getrootelement() node
from (select sql_stmt xml from export_jobs where exp_id = 28) xml,
table (xmlsequence(xml.xml.extract('//*'))) tBut I get this error: ORA-22806: not an object or REF. (It might not be the way to go after all, as it's not proper xml, being as there are no corresponding close tags, but I was trying to think outside the box. I've not needed to use xml stuff before, so I'm a bit clueless about it, really!)
I tried casting sql_stmt into an xmltype, but I got: ORA-22907: invalid CAST to a type that is not a nested table or VARRAY
Is anyone able to suggest a better method of trying to extract my tags from the clob column, please?

I don't know if it may work for you, but I had a similar activity where I defined sql statements with bind variables (:var_name) and then I simply looked for witch variables to bind in that statement through this query.
with x as (

Can anyone help out there?
The website I need help with is

Thank you...
If you want to help, I can compensate you for helping with an
immediate page..

Thank you for writing. I do need your help, and here's the

Various Direct Debit and Billing Help Needed

FAILURE TO DELIVER BILL IN PAPER FORMAT: Firstly when I discovered that my account number was encrypted in the email and that I could not pay the bill online, without having the whole account number in full - I contacted BT who told me that they would post my bill and it would arrive in paper form. A week later, no sign of it so phoned again and again I was told that another paper copy would be sent out - waited another week - still no sign! Got a reminder email that my bill had not been paid - doh! I knew that but I was trying to get that sorted out! So phoned again today and the guy in India or wherever the heck he is, told me that he would setup a profile on BT.com for me and this would allow me to pay online.
TEMPORARY ACCESS TO BT.COM?: The email address which this member of staff had set up on BT.com for me was identical to my old btinternet.com account minus a number! The new email address with this new account is somewhat different and when I try to edit simple information on the profile page, it does not allow me to do so. Can anyone explain why?
UNABLE TO SET UP DIRECT DEBIT: I log-in to My BT (whether it's temp. access or not) and then click on Bills and Payments but instead of more options I get a graphic which has got "Ugrade to an online account" on one side and "Help with Billing and Payments" on the other side. When I click on "see all billing and payments help" nothing happens and in fact NONE of the links work.
Would it be the better idea to re-register with BT.com and this time put the correct BT email address in, the one that i was given with this account - see if it works that way?
PLEASE HELP!!!

This is essentially a customer to customer help forum; I could make one or two suggestions which might explain things but would be equally likely to complicate the matter. It all looks a bit messy and you need to get BT's help in sorting it out. The moderators who oversee this forum are jolly good at that and you can contact them here: Contact BT Care Team.
They are busy and may take a few days to respond but will contact you by email or phone, and will have access to your account in order to put things straight.
[Edit: My daughter turned up in the middle of writing this and by the time I posted it KB had replied in similar vein.]

External USB encryption key (dm-crypt and luks) - help!

Hi, I've been following the 'System Encryption with LUKS for dm-crypt' wiki during my new laptop install - but am stuck on one bit.
On this line:
echo 'KERNEL=="sd*", ATTRS{serial}=="$SERIAL", SYMLINK+="$SYMLINK%n"' > /etc/udev/rules.d/8-usbstick.rules
What do I put in for the $SYMLINK%n ? is this a link to /dev/sd .. something? Or is it a name for the device?
Many thanks in advance for any help!
Last edited by TornadoTDi (2008-08-27 13:04:10)

Thanks for your reply. The wiki page does say:
"Replace $SYMLINK and $SERIAL with their respective values. %n will expand to the partition (just like sda is subdivided into sda1, sda2, ...).".
Now, the $SERIAL part can be obtained, but it's not clear what form the $SYMLINK variable is in...

USB Flash Drive issues, FAT and Windows, Help!

Here's the deal:
I have a flash drive, I formatted it in FAT because it needs to be used on my Mac (Snow Leopard) and Windows. When I format it, it adds 2 or 3 other partitions like 200MB. BUT does not show it in Disk Manager or in Finder. I can read and write to the drive on my Mac, and it works (Mac thinks it's FAT). When I go to Windows it says it needs to be formatted. So after a leg-breaking experience in XP to reformat it as FAT, I can't just drag and drop folders into it. If I drag a folder to it it gives me an error code -36. HOWEVER, I can make a new folder on the drive (CommandShiftN) and drag files into the new folder. What the heck? Never had these issues in Leopard. What is the issue? Is this just Snow Leopard or is something screwed and I need to reinstall? Help. Thanks in advance.

1) Open Disk Utility.
2) Click your flash drive.
3) Click "Partition" tab.
4) Change "Volume Scheme" drop down box to 1 partition.
5) Change format to FAT.
6) Click "Options" button.
7) Change partition table from GUID to Master Boot Record.
8) Click Apply.
All done.

Mac Mini and WPA Help needed

I just upgraded my wife's USB wireless adapter to a Linksys WUSB54G which supports WPA. When I try to invoke WPA personal from my macmini, I get a message that reads that my macmini is not WPA capable. Both machines are attached to an Airport Extreme. The airport is running 5.5.1. I'm running 10.4.2 on the macmini.
I'm almost up to date on my airport software, running, I think 4.1. I've seen postings warning against 4.2.
What am I missing?
Steve

Indeed - but the preceding discussion came about because someone wanted to use WPA security on a Mac running 10.4.2 without installing the Airport 4.2 update. That will work (as was already pointed out above) but you will get a non-fatal error message when attempting to do this.
I do understand the original poster's concerns over installing the Airport 4.2 update. While the vast majority of people (like yourself) have no problems, there are still a sizeable number of people who run into trouble when installing this update - and recovering from that problem can sometimes take nothing short of a complete reinstall of MacOS 10.4.

Flash fading movies and sound-HELP NEEDED

hey guys i need some help
firstly if u want to help me could u please visit this site
http://www.thetimemovie.com/
this site is what i want to do
notice the fading pictures that can be controlled and the
sound bar at the bottom on the left
Any help would b aprreciated GREATLY
thanks in advance
BUTCH101
PS: email [email protected] if u have any info
thanks

What I see in the sample site is that the "sound bars" aren't
sync'd at all. They are just a looping clip that stops in diagonal
shape when clicked. And, the sound is not actually being stopped
when you click the bars. Rather, the actionscript is actually
turning the volume down, gradually. The sound is still continually
playing, you just can't hear it. This is evident in the fact that
when you restart the sound, it picks up not where you left off, but
at the point where it would have been anyway, had you not clicked
the button.
I believe that the sound is set to streaming and as such can
be dealt with frame by frame. So, your real quest is to have
someone (more knowledgable than me) provide sample code that would
begin reducing the volume of the sound object in increments as the
movie moves through frames. Something like:
onFrame (95){
mySound.setVolume(80);
onFrame (110){
mySound.setVolume(60);
onFrame (120){
mySound.setVolume(40);
onFrame (130){
mySound.setVolume(20);
onFrame (140){
mySound.setVolume(10);
onFrame (150){
mySound.setVolume(0);
Obviously, you wouldn't use frame numbers, but a variable
representing the current frame relative to the frame the movie was
in when you clicked the button.

OS X Yosemite and CS6 help needed.

I have a MacBook Pro (2013) which I want to update to OS X Yosemite but I have one question about CS6.
When I update my Mac system to OS X Yosemite do I have to remove and reinstall CS6? Or can I leave the program on my Mac and update it when OS X Yosemite is ready?
I'm quite worried about this because I'm a student who needs CS6 every day to make my homework. Any help would really be appricated!

SWF and FLV - help needed

Hi,
I'm finding flash very difficult, i've read tutorials and i still find it confussing. What i'm trying to do is embed my FLV video into my website that keeps my XHTML 1.0 Transitional page vaild.
I download swfobject 2.2 and i have a FLV file that i exported from premiere pro CS3, from what i understand i need SWF file to go with the FLV.
When i import my FLV into Flash CS3, choose the skin i want then export everything. I then have three files; FLV, skin and the player. What i don't understand is, i've seen certain skins that are two in one, both the skin and the player.
Could someone please tell me what are the main files that i require in order to get my flash on my html page.
I've spent hours trying different embed codes and nothing seems to work.
I've created a lot of websites, but when it comes to flash i'm puzzled.
Any help is much appreciated, thanks.

Thanks for your reply.
I eventually got everything working with swfobject.
I think i'm finally getting the hang of flash, well the basic stuff anyway, lol.

Find and replace help needed, multiple variables

Hi everyone,
Im trying to find all urls in my code that start in a particular way but have a number variable at the end, see examples below
<a href="/example/examplefolder/enquiry.asp?pid=123">
<a href="/example/examplefolder/enquiry.asp?pid=485">
<a href="/example/examplefolder/enquiry.asp?pid=284">
and replace them with one url, see example below
<a href="/example/examplefolder/default.asp">
How can I use Dreamweaver find and replace to achieve this across my whole website?
So far I only know how to find one thing and replace with another, rather than finding variables and replacing them with one thing.
Thanks for your help with this!

In the Find field of the Find and Replace dialog box, enter this:
(href\s*=\s*\"\/example\/examplefolder\/enquiry\.asp)\?pid=\d+(\")
In the Replace field, enter this:
$1$2
Select the "Use regular expression" checkbox.
Explanation:
The two sets of parentheses are capturing groups, which capture the actual values as $1 and $2.
The \s* matches zero or more spaces.
\" matches a double quote.
\/ matches a forward slash.
\? matches a question mark
\d+ matches one or more numbers.
I have written a two-part tutorial on using regular expressions, which can be found here: http://www.adobe.com/devnet/dreamweaver/articles/regular_expressions_pt1.html.
