Table 9.4: Status Control Commands
Command Description
AT+CMER
Mobile Equipment Event Reporting:
AT+CMER=<mode>,0,0,<ind>,0
Mode:
0 - Discard "+CIEV" and "^SLCC" URCs.
1 - Discard "+CIEV" and "^SLCC" URCs when TA-TE link is reserved, e.g. in
online data mode. Otherwise they are forwarded directly to the TE.
2 - Buffer "+CIEV" and "^SLCC" URCs in the TA while TA-TE link is reserved,
e.g.
in online data mode, and flush them to the TE afterwards. Otherwise they are
forwarded directly to the TE.
3 - Forward "+CIEV" and "^SLCC" URCs directly to the TE. If TC65 is in online
data mode, URCs are signaled via sending BREAK (100ms) and stored in a
buffer. Once it is back in command mode e.g. after +++ was entered, all URCs
stored in the buffer will be output.
Ind:
0 - Disable indicator event reporting.
2 - Enable indicator event reporting.
