Test Commands
Rev. 8 May.12 Proprietary and Confidential 121
!KEYON
Supporting chipsets:
• MDM9600
Note: The modem must be in
FTM mode to use this
command—use
!DAFTMACT
to enter FTM mode.
Key on the transmitter
Tune the radio, key the transmitter at maximum, and select pseudo-random noise or a
sine wave signal.
The power amplifier is set to maximum gain and the output power limit is disabled.
Note: This command enables the transmitter circuitry—!TX does not need to be used
before !KEYON.
To turn off the power amplifier, use !KEYOFF on page 120. To turn off the transmitter,
use !TX on page 123.
Usage:
• Execution: AT!KEYON=<channel>,<band>,<wave>
Response:
OK
Purpose: Key on the transmitter
Parameters:
<channel>
• 0–799, 991–1023 (Cellular)
• 0–1200 (PCS)
<band>
• 0=US Cellular
• 1=PCS
<wave>
• 0=PN (pseudo-random noise)
• 1=SINE (sine wave)
!OSDSM
Supporting chipsets:
• All
Display memory usage for DSM buffer pools
Display memory usage of the DSM (Distributed Shared Memory) buffer pools. This
provides a means of detecting memory leaks.
Usage:
• Query: AT!OSDSM?
Response:
Pool n Size <size> Free <free>/<max> Min <min free>
...
(list displays one line for each buffer pool from 0 to n)
OK
Purpose: Display memory usage.
Parameters:
All values are ASCII strings representing hexadecimal numbers from 0x0000 to 0xFFFF.
<size> (Size (in bytes) of each item in the pool)
• Valid range: 0x0000–0xFFFF
<free> (Number of items currently available in the pool)
• Valid range: 0x0000–0xFFFF
<max> (Total number of items in the pool)
• Valid range: 0x0000–0xFFFF
<min free> (Lowest number of free items since power-on)
• Valid range: 0x0000–0xFFFF
