How to control the KNX bus via SMS and send notices via SMS?

[ferrim]

With this low cost USB 3G Modem I need to add one init string in the resident script:

Code:

    -- set to pdu mode
    modem:send('AT+CMGF=0')
    -- enable sms notifications
    modem:send('AT+CNMI=1,1,0,0,0')
    -- fixup encoding
    modem:send('AT+CSCS="GSM"')
    -- set preferred sms message storage to SIM
    modem:send('AT+CPMS="SM", "SM", "SM"')

and using the ttyUSB2 (the third USB) everything seems to work fine.
The Huawei E173 are a little expensive and hard to find...
