Download PRL +DPRL
Description:
Syntax:
Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide (PN S000478C)
This command is used to download a Preferred Roamer List (PRL) to the modem. The PRL must
be formatted in accordance with TIA/EIA-683-A.
The +DPRL command is part of the Wavecom suite of service programming commands. The
modem service programming code must be successfully entered (see +WSPC) prior to using this
command.
The +DPRL command is a multiline command, which means that the modem will expect the host
to continue to input data after the first line of command is entered.
The first line of the +DPRL command consists of four parameters and a carriage return. The
parameters consist of the target NAM number (1 or 2), current sequence number, last sequence
number, and length (in bytes) of the PRL data in the current sequence. The PRL data can be
large in size (up to 16k Bytes). The host may divide the whole PRL into multiple sequences if it
doesn’t have a large enough buffer to hold it. The sequence number needs to start from 0 to tell
the modem to start counting the sequence number. To send the next sequence, you need to use
the same command (+DPRL) and only increment the sequence number by 1. You may split the
PRL into no more than 255 sequences. When the last sequence equals the current sequence, the
modem will put the PRL data altogether and start processing it.
The second line of the command consists of <PrlData>, which is a stream of bytes usually
encoded in hexadecimal. The number of bytes must equal the length specified in the first line. It is
not recommended to manually type the <PrlData> since some of the ASCII characters are
invisible. If you are using HyperTerminal, you may use the send text file feature to download a
PRL.
Once the PRL has been successfully downloaded to the modem, the +WCMT=1 command must
be used to save the PRL to NV memory and activate it. The PRL is validated as part of the
commit operation and the validation result is returned using the +DPRL unsolicited response. A
downloaded PRL that fails validation is not activated and the old PRL, if any, remains in effect.
To abort PRL download prior to final commit, use the AT+WCMT=0 command. To re-start the
download sequence, set the current sequence number (<cur_seq>) to zero.
Command syntax: AT+DPRL=<nam>,<cur_seq>,< last_seq>,<length><cr><PrlData>
Command
AT+WSPC=1,0000
Note: Enter service programming code. The
SPC code for your modem may be different.
AT+DPRL=1,0,0,18<cr>
Note: Target NAM is 1, current sequence is 0
(start), last sequence is 0 (total 1 sequence),
total bytes in current sequence is 18.
Use HyperTerminal’s “Send Text File” feature
to send the PRL file , or use your application
to send 18 hexadecimal data bytes
AT+WCMT=1
Note: Save the PRL in NV and activate new
Nam1 PRL.
Possible Responses

Note: PRL stored in modem.
+DPRL:0
Note: PRL validated.
OK
Note: Modem software reset begins.
+WIND: 8
Note: Modem software reset complete.
