Is this a known device with a solution?
Thanks

I am leaving away -> AT+CNMI=0,0,0,1,0 but this doesn't help:

seems to be a strange modem ....

I have introduced a "sleep 4" before starting smsd after plugin the modem to USB,
now everything seems to work:

In my /lib/udev/rules.d/76-GSM-Modem.rules file:
KERNELS=="5-1:1.0",SYMLINK+="GSM-Modem",GROUP="uucp",ACTION=="add",RUN+="/etc/init.d/sms3-marcel restart"
(in /etc/init.d/sms3-marcel a sleep 4 is added)

It seems the modem needs some seconds after getting power before we start
talking to it.

regards
Marcel

It is a Siemens Module MC388 or 389
