Huawei E220 Boot loop?

[wg]

Hallo,


an einer Linux ist ein Huawei E220 HSPDA USB Modem angeschlossen.

mit

~> ls -l /dev/ttyUSB*
crw-rw---- 1 root dialout 188, 0 2013-12-12 09:07 /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 1 2013-12-12 09:10 /dev/ttyUSB1

sieht man die erkannten devices.


Aus Konsole 1 erfolgt die Eingabe
~> echo -e "ATZ\r\n" >/dev/ttyUSB1
~> echo -e "AT+CMGF=1\r\n" >/dev/ttyUSB1
~> echo -e "AT+CPIN=\"1234\"\r\n" >/dev/ttyUSB1
~> echo -e "AT+CPIN=\"1234\"\r\n" >/dev/ttyUSB1
~> echo -e "AT+CMGF=1\r\n" >/dev/ttyUSB1
~> echo -e "AT+CMGF=1\r\n" >/dev/ttyUSB1


Ein 'cat /dev/ttyUSB1' auf Konsole 2, vor Einage auf Konsole 1, zeigt
folgendes Output:

--- <output> ---
ATZ


OK

Frage:
Was bedeuten die alle 30 Sekunden wiederkehrenden Meldungen
^BOOT:27046241,0,0,0,6


Ich hab das Modem unter Windows mit der mitgelieferten Software vor dem
Anschluß an Linux ausprobiert, da ging alles bestens.

Nachdem ich auf der Linux einigemal verschiedene AT Befehle ausprobiert
habe, scheint das Moden nicht mehr zu gehen, auch auf Windows nicht mehr.

Frage: kan man ein Modem mit AT-Befehlen beschädigen?

Ein Rücksetzen mit AT%F hat nix gebracht.





Danke fürs Lesen und Hinweise,
