5.7 Siemens-defined AT commands for enhanced functions
Self-defined commands do not have to be implemented in accordance with the official syntax. The "+C" string can there-
fore be replaced by "^S" ("^" = 0x5E). If a self-defined command with the same syntax is to be included in future in the
GSM recommendations, the command can be addressed with both strings.
