current channel number.
ATGP
Group Number – Set/read the group number for this unit.
0 means ignore the group number. 1-255 is a group identifier.
Only M7s with the same Group Number will communicate
together.
0-255
0 (ignore
group
numbers)
ATH0
Hang-Up – Tells the M7 to stay off-line. Effectively does
nothing.

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. See
technical bulletin AN163 for more information about this
