Hi there,

I would like to get some advice in using a Siemens M20 modem, my details are:

Operating system name and version: SUSE Linux Enterprise Server 11 Patchlevel 1
Version of smsd: 3.1.14
Smsd installed from: sources
Name and model of a modem / phone: Siemens M20
Interface: USB

My modem is currently configured like this:
Quote
[GSM1]
device = /dev/ttyUSB0
incoming = yes
pre_init = yes
init = AT+CBC;+CSQ
pin = ****
smsc = 49173*******
baudrate = 19200
report = yes

When trying to send an SMS, the following error log output occurs:

Does anyone have a hint on this "error 500" thing?

Hmmm, I just accidentially detected a possible cause for the "error 500" thing... when trying to use the modem manually (e.g. with kermit) the same things happen, but when I try to init a voice call into the mobile network, then NO CARRIER occurs, while a voice call to a landline number works fine. Looks to me like a problem with the SIM card, but what kind of problem could cause that?

Ok, for the ones that already read this - forget it - the problem was so simple - wrong number in smsc configured ...
