AT$H
On-line timer
– If set to 0 (the factory default setting), the M7
will always revert to the operation-mode(on-line). This is the
factory default operation, and is the way the M7 has operated
since its inception. Set to 10 or more to configure M7 to revert
off-line (command mode) if more than xxx seconds pass with
no TX or RX data. C22 or higher firmware required.

is within 20% of actual current draw.
Range: 0-9999
