Hi,
Now I tried to send GSM codes (like *#21#, oder
*21*{NUMBER}#) to set and
unset call diverts. It seems, that "call 1 *21*{NUMBER}#" does not work.
Normal GSM cellphones seem to handle these codes not as a normal call.
Theses are called USSD and are not implemented in mobile yet
Unstructured Supplementary Service Data (USSD)
GSM 03.90 IIRC.
Does anybody know how one could send GSM codes to the
network?
Sure:
Read the specs for USSD, implement them and submit the patch :)
Cheers,
Sylvain
