ATRQ
Receiver Signal Level – Reads the Receiver Signal
strength this instant, and returns the level in dBm.
Range: -40 to –130 (dBm)
-
ATRS
RSSI (Receive Signal Strength Indicator) – Returns the
signal level of last received packet. The reading is in dBm.
Usable for relative comparison of signals, but absolute value
is within10dB at -90dBm.
No parameters. Returns a
number : -50 to –140
(dBm) varies by model.

modem will respond to over-the-air RPR requests, Pings, and
over-the-air commands. Default is OFF (1).
0 = Remote Access on
1 = Remote Access off

anything but 255), sets the pre-data time for CD Data
Framing (See 15.1 for more information)
0-254 = Enabled
255 = Disabled
255

LPM Operation Enable –
When set to 1, the DTR input line
controls the M7’s low-power operation. When set to 0, the M7
will not go into LPM, regardless of the state of the DTR pin.
When set to 2, the modem is forced into a low-power mode,
disabling the receiver. The unit will still transmit data in sleep
mode 2. Mode 4 keeps RX off but will transmit data.
Range: 0, 1, 2, 3, 4

– When issued, the modem will begin
transmitting data. The type of data sent is set in the
parameter. Entering a <CR> will terminate the transmission.
0 = Go back to normal
1 = Random
3 = 1010… at ¼ baud rate
4 = TX all 0s
