Set command enables/disables sending of unsolicited result codes from TA to TE in the
case of indicator state changes (n.b.: sending of URCs in the case of key pressings or
display changes are currently not implemented).
Parameters:
<mode> -
controls the processing of unsolicited result codes
0 - discard +CIEV Unsolicited Result Codes.
1 - discard +CIEV Unsolicited Result Codes when TA-TE link is reserved (e.g. on-line
data mode); otherwise forward them directly to the TE.
2 - buffer +CIEV Unsolicited Result Codes in the TA when TA-TE link is reserved
(e.g. on-line data mode) and flush them to the TE after reservation; otherwise
forward them directly to the TE.
3 - forward +CIEV Unsolicited Result Codes directly to the TE; when TA is in on-line
data mode each +CIEV URC is replaced with a Break (100 ms), and is stored in a
buffer; onche the ME goes into command mode (after +++ was entered), all URCs
stored in the buffer will be output.
<keyp> - keypad event reporting
0 - no keypad event reporting
<disp> - display event reporting
0 - no display event reporting
<ind> - indicator event reporting
0 - no indicator event reporting
2 - indicator event reporting
<bfr> - TA buffer clearing
