Hello, I have to use a securid card (constantly generates a code) to log in to our ras server at work.

On the laptop the afterdial terminal option is enabled, I enter no password/username click dial and a window pops up for me to enter the username and generated password.

I cannot find a way of using an afterdial terminal on the zaurus.

I have tried putting the securid password in before I dial but this doesn't work, possibly because the password has changed by the time it connects.

I am connecting via bluetooth which works for internet through gprs ans also works when I dial up a gsm internet provider.

Anyone got this working?

I guess it was bound to happen.

It's a shame that it's only a proof of concept and ask permission to install itself.

Still, the majority of ppc users would probably still install it biggrin.gif

First off, many thanks to Derekp for discovering this setting, my tests reveal (as did Dereks) that this significantly improves sd/cf read/write speeds at no apparent cost to stability.

In fact my Sandisk card which normally screws up after a single suspend when formatted to ext2 now works fine with ext2.

So removing this setting not only provides blinding speed improvements, but is more stable.

I would love to know the reasons for the existance of this setting, as removing it gives a truly massive improvement, and so far, no downside.

TEST 1
======

The test file was a 46,409,728 byte tar file ( a backup from my c760 ).
I chose large files to try to eliminate buffer cache form the copy tests.
The first test was copy the file from my 512mb kingston cf card to my 256mb sd card (both formatted as fat16).
The second test was to extract the copied tar file from the sd card, to the sd card.
tests done on 5500 and c760 models.

The roms were all stock install, other than specified differences.
CODE
               copy from       tar -x

5500            cf to sd        sd->sd.    

=======================================

As above but    1m13s           1m59s     9sec

overclocked,    635749 b/sec

cpu 471mhz      620 kb/sec

bus 235mhz


Observations,:-
1: The c760 is much faster for sd read/write. due to a faster bus speed, (already a known fact from previous tests)
2: Overclocking the c760 resulted in a further but small speed increase, again due to faster bus speed.
3: The overall write speed is not really much faster. (expected result)
4: Extracting tar files is much quicker due to removing redundant writes. (expected result)
5: Deleting lots of files shows the best improvements (535 seconds down to 9seconds), as it is only accessing the fat table (again this was expected).
6: One reason why Oz, performed better in the extract was the tar file had loads of symbolic links, oz did not display any error messages for these, but could not write them out as it was fat16.
The other roms did display error messages and had to spend cpu time doing this.
on the c760 test, I used 2>/dev/null for both extracts so screen display of error messages was removed.
7: Sadly I didn't test the delete times on the 5500, but expect similar improvement.


TEST 2
======
As my backup had several large files on it 7-14mb I decided to test an archive of my news spool which contains lots of small text files. I also tested the cf card in a similar way to the sd test.

test2 news.tar file contains 7063 small text files size is 25,461,760 bytes
Test done on c760 only
CODE
               copy from      tar -x    delete         tar -x   delete

c760            cf to sd       sd->sd    files          cf->c    files

Cacko QT        39sec          5m46s     32s            4m14s    19sec

CONFIG_FS_SYNC  652865 b/sec

disabled        637 kb/sec



As above but    32sec          4m52s     27s            3m38s    16sec

overclocked,    795680 b/sec

cpu 471mhz      777 kb/sec

bus 235mhz


Observations:-
1: CF is way faster than sd regardless of settings (already proven fact).
2: Speed improvement between sd and cf is not as much when disabling CONFIG_FS_SYNC.
3: read/write speed is dependant on the bus speed, buying 32x sd cards is a waste of money as the bus on the Zaurus is not up to the job and offers no speed improvement over a standard speed card (again proved by me in other speed tests).

Check out this console app :-

http://killefiz.de/zaurus/showdetail.php?app=1667

It is totally awesome!

On the cxx0, you can use the fn_1/fn_2 keys to zoom in and out from the smallest font possible right upto "/home/zaurus" taking up half the screen!

You can also go full screen by clicking an icon. it is suposed to go fullscreen with fn-5, but I can't get this to work with the cacko rom, maybe fn_5 is remapped in this rom???

Either way, to finally get a full screen shell is now possible, makes all my character based apps (slrn) work so much better.

This is the dogs b*ll*cks, if the author reads this, then well done mate, a fine piece of code!

I don't know if it works on the sl5x00 range, I may try it later on my 5500.

HI,

I am after a bluetooth card and spotted this on EBAY.

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...6&category=3730

Does anybody know what card this is, and will it work on a C760?

or this one?

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...5&category=3730

Everybody raves about the socket card and I would buy one, but the last post I saw concerning them said that the new revision (G) does not work, and you have to get a revision F card.

Does this still apply? I think it may be hard to find a revision (F) card now.

Peter.
