Soft Reset
Description:
The soft reset command is used to return the modem to the initial conditions upon power up. The Soft
Reset will return S Registers to their stored values, restart the channel scan process, clear all data buffers
including any pending data that is still contained within the modem. The modem will shut down any
existing stack in an orderly manner. A soft reset will de-register a modem from the CDPD network if
necessary.
In PROG mode, this command may be used to exit without saving any NVM changes.
Format:
ATZ
To perform a modem soft reset
Validity:
Valid for AT Command and Program Modes.
Other Considerations:
Upon issuing a Soft Reset, the modem will disconnect from the CDPD Network and restart the channel
scan procedure. This results in a temporary lapse in the modem’s ability to send or receive data. Before
initiating a data mode session (PPP, SLIP, UDP or TCP) immediately following a soft reset, it is
recommended that the application verify that the modem is registered on the network.
