Subject description: script to get content of SIM Card		  
I am working on a script to fetch all possible stored data from the SIM card of my broadband usb modem .

It goes something like this :

1) create a database file with the current supported AT commands by sending ' " AT+CLAC" |tr ',' '\n' |sort -d >database.file ' .

2) read the databasefile line for line and send
"AT${line}?" to show the current setting
and
"AT${line}=?" to show the supported settings .

Sending the AT commands i came up using the /usr/sbin/modem-stats binary , which is the best tool i have found so far .

Now i have the problem to locate the source for "modem-stats" .

I can not find it on google, debian, ubuntu, bkhome.org/sources or inside woof tarball .

Could anyone point me there ?

WOW ! From 1995 !! Not found even on archive.debian.net ..

At least the second time you've helped me out Panzerkopf !

Now i've something to chew on !

The problem is i have overstepped my 5GB limit and my second provider had apparently cut me off while dl win8 preview 64bit .iso . They apparently wanted me to confirm to order some GB more at UMTS speed while looking for /usr/bin/defaultbrowser, which was of course not available ..

My first provider squeezed the speed to 8KB/s without problems, which my second provider also did in former days (did not happen many times) .

So i got me a 2,5GB win.iso.part and a 750MB win.iso and want to wget -c it .

Somehow i was not able to connect anymore with Puppy to internet and also not able in windows .

Now the month from 6th to 5th is a new month and i can connect with windows, but pgprs-connect does still not work anymore, nor pupdial .. Grrrrr ...

Installed hyperterminal from xp to vista and here not much garbage output, but also a short CONNECTED 7200000 and "NO CARRIER" ..

Posting from racy with my first provider ...

Cannot get the SMS from the card :

AT+CMGF=1

AT+CMGL='"ALL"'
[empty space here]
OK

Seems that the SMS gets directly somewhere to c:\USERS\USER\AppData\Roaming\Vodafone ...

Some people say linux has a complicated folder structure , haha ..

Now my provider has turned up the download speed again and i can connect with pgprs-connect . Will take me some time to figure out settings to connect in isdn mode ..

So here's my get_modem_values.sh script :
It works pretty well at my 2 years old and grown 5GB+ Puppy-4.3x full installations,
while on Puppy-5.1.1 it got me a bunch of crap as answers to modem-stats -c AT$COMMAND $DEVICE

Code:
#!/bin/bash

DEV_MODEM=/dev/ttyUSB0
CLAC_FILE=/modem-stats_AT+CLAC.sort_d.txt
VALUE_FILE=/get_modem_values.txt

Version=1.0-Puppy-4.3x

usage(){

exit 0


Note 1 : Every MODEM seems to have its own registers and commands, so it is probably the best to adjust to the needs, especially the "dangerous_func" .
Note 2 : googling "AT COMMANDS" gives a large amount of hits with a lot of PDFs .
Note 3 : My modem needs to be unlocked with pin=$MYPIN to answer the at+clac command to build the database .

Hi Karl !
As far as I know, every modem has Hayes compatibile commands and as option - some extended commands.
Also, some modems have own additional vendor specific commands.
This should be described in these standards: TIA/EIA-602, V.250 and GSM07.07
