Emulates ME keypad by giving each keystroke as a character . Ifemulation fails in an ME, an error, +CME ERROR: is returned. Thiscommand should be accepted (OK returned) before actually starting topress the keys. Thus unsolicited result codes of key pressings and displayevents can be returned (see AT+CMER). It will also be possible to receiveunsolicited event for CKEV when an EKEY is sent to the ME. For example,this makes it possible for a connected Bluetooth device to be controlled bythe EKEY command.The physical keypad always has higher priority than emulation of key-strokes via AT*EKEY. That is, if the physical keypad is operated duringexecution of a series of keystrokes generated by AT*EKEY the emulatedkeypad operation is terminated immediately.
To use some of the keys, a specific character set has to be set viacommand AT+CSCS=. For example, the characters “[“ and “]”used to emulate the left and right selection keys on the phone are notincluded in the default GSM character table. To handle this issue, the8859-1 character table can be set by first sending AT+CSCS=”8859-1” tothe phone.
