Command
Table 3. AT Command Set (Continued)
Single Chip Modem with Integrated Controller, Data Pump, and AFE
Function and Description
#QSIb
After the download command is issued, the host controller waits for the modem
to return an ASCII ACK (0x06), then transmits the table of country parameters.
The modem returns a result code after the download completes, either OK or
ERROR. If an ERROR result code is returned, the host controller is expected to
reset the modem.
The country parameters stored in RAM include all the parameters stored in
EEPROM or ROM except the client message (AT14), the S-register defaults
and limits, and the adjustable transmit levels. The modem uses the copies of
these parameters kept in the optional EEPROM, or the ROM.
Download a table of parameters as binary 8-bit data. Use
this format when the host controller sends 8-bit data to the
modem (that is, when no parity bit is used on data sent to
the modem).
