\Tn Inactivity Timer Limit
The AT\Tn command specifies length of time (in minutes) that the
modem waits before disconnecting when no data is sent or received. The
time period can be set at n = 0 - 255. A setting of zero disables the timer.
As an alternative, the timer may be specified in S-Register S30. This
function is only applicable in buffer mode.

which the last call attempted in the past two hours failed. In countries that
do not require blacklisting, this command returns ERROR.
