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.
AT+CMER in online data mode, and flush them to the TE afterwards. Otherwise they are
forwarded directly to the TE.

stored in the buffer will be output.
