[outdated] smsd stops working with mobile broadband

Location: Kgs. Lyngby, Denmark
Operating system name and version: Fedora 14 (Laughlin)
Version of smsd: 3.1.8
Smsd installed from: package repository
Name and model of a modem / phone: Sony Ericsson Z530 and Huawei E182E USB modem
Interface: USB

I previously reported a problem with my Huawei E182E 3G/HSPA modem when trying to use it with smsd.

I have now found out that the poblem is that if you connect the modem to your USB port but do not define the modem in NetworkManager as a mobile broadband modem then smsd works fine.

AS soon as you define the modem in NetworkManager and use it for mobile broadband then smsd stops working.
This means that the linux kernel and/or NetworkManager can not handle smsd and mobile broadband simultaneously.

The problem even occurs if you connect another modem like e.g. as I have done a Sony Ericsson Z530 as a modem and configure this modem to use smsd, and not the mobile broadband modem. As soon as you define the mobile broadband modem in NetworkManager the smsd (Sony Ericsson Z530) stops working (ERROR is timeout, i.e. the modem does not answer).

I wonder if there exists a workaround for the above problem?

Sorry for the late answer :(.

I do not know about Fedora, but generally taken 3G modem may provide two ports: single port for the modem itself, and another port for "UI Interface". Even when 3G connection is active, SMSTools should be able to use the another port for SMS messaging, if the port is free. If it's not free, it cannot be used.

The issue with Sony Ericsson is strange. Mobile broadband with Huawei should not have any effect with different modem which has nothing to do with broadband usage. Perhaps this issue is caused by some configuration problem, but I do not know what it could be.

I do not use 3G broadband with any Unix or Linux, so hopefully some members of Community have some information which may be helpful.
