Hello people, I'm trying to connect my gsm modem (siemens mc35i) to my linux redhat pc. I use minicom to cofigure it and i create a symbolic link with command line " ln -s /dev/ttyS0 /dev/modem. After launching "minicom modem", AT command return me OK but but when i try to define my PDP context with "AT+CGDCONT=1,"IP","free" " it return me ERROR. Can somebody help me please? I need it before using SMSlib for my internship.
