Modem problem - bad communication with
 

Good Mornig!

I have bought the Sony Ericsson GC89 GPRS/EDGE/WLAN modem, and the Ricoh PCI to CardBus controller for my desktop PC. When I trying to init modem, for exampel, with minicom at start was printed many characters, like “}!--”. No AT*, AT+CFUN, AT+CPIN commands work.

I think this problem can be interested for Linux developers

Please help!
Regardes,

I have resolved my problem, it was simple, but I haven't think so much simple).
It was enught to set bud rate to 57600 bps.

I assume you have used original windows driver and ndiswrapper. I think I have sucessfully installed ndiswrapper but where did you found the driver? oryginal CD contains only an .exe file. stachu

Sorry, for time You have wait for my reply, but I have much work and I've just forgot :-)

I don't use ndiswrapper (in particulary I don't know exactly what is it...).
I have a desktop machine, so I've must bought the PCI to PCMCIA bridge and it work like normally PCMCIA / PC Card slot on laptops.

So first, You must turn on PCMCIA and PC Card (!) support in kernel and support for UART compatible chips.

Next, try to install pcmcia-cs package and start it (try to add pcmcia-cs to your system services). Don't worry about bad identification of your card.

If everytttyS2 at I/O 0xc000 (irq = 16) is a 16550Ahing is OK in dmesg you will see something like:
ttyS2 at I/O 0xc000 (irq = 16) is a 16550A

You must manually obtain the device file, as I've read the pcmcia-cs package docs this device file can change.

Next configure minicom. The most important is speed 57600 kbps - no much no less! My configuration looks like 57600 8N1.

And its all! Your modem now response to commands.

For make connection send
AT+CFUN=1
AT+CPIN=<YOUR PIN>
ATDT**99***<CID>2#

You must set CID manuall or by Windows software for modem, see AT Command References included with modem for more deatils.

Good luck!

P.S. If You have future question write, and I will try to answer as best I can. Sorry for my english.
