| 314 The fundamental operating model of all message stores for SMS (whether SIM or | |
| 315 phone-based) is that received messages accumulate (and possibly sent ones too, | |
| 316 if they are stored in this manner), the limited available memory fills up, and | |
| 317 then the user needs to clean out the accumulated messages, preferably also | |
| 318 archiving them by transferring to a larger computer for longer-term storage. | |
| 319 Given this fundamental operating model, we only need to provide commands for | |
| 320 dumping the content of the message store and for cleaning it out - there is no | |
| 321 real need to implement commands for writing messages into the store. | |
| 322 | |
| 323 The extent of special support for the SIM SMS store in fc-simtool is rather | |
| 324 minimal because it just so happened that we already have external tools that do | |
| 325 a major part of the work. Some phone firmwares, particularly that of the | |
| 326 Pirelli DP-L10 phone currently used by the Mother, implement their on-the-phone | |
| 327 SMS storage by a way of a file in their local flash file system whose binary | |
| 328 format just happens to be exactly the same as the binary format of SIM-based | |
| 329 EF_SMS if all 176-byte records are simply abutted together in the host-based | |
| 330 binary representation. A few release cycles ago we added a new utility named | |
| 331 pcm-sms-decode to our FreeCalypso host tools suite; this utility reads a binary | |
| 332 file in this "EF_SMS records concat" format and performs the quite involved job | |
| 333 of fully decoding all messages into human-readable form. Given that we have | |
| 334 this external pcm-sms-decode utility, all we need to do in fc-simtool is save | |
| 335 all records of EF_SMS into a single concatenated binary file, and let | |
| 336 pcm-sms-decode do the rest. | |
| 337 | |
| 338 Our dedicated commands for working with the SIM SMS store are as follows: | |
| 339 | |
| 340 save-sms-bin host-filename | |
| 341 | |
| 342 This command saves the full content of EF_SMS in the named file in the host file | |
| 343 system in binary format, suitable for further decoding with pcm-sms-decode. | |
| 344 | |
| 345 sms-erase-all | |
| 346 | |
| 347 This command erases every record entry in EF_SMS. | |
| 348 | |
| 349 sms-erase-one rec | |
| 350 | |
| 351 This command erases the specified individual record in EF_SMS. | |
| 352 | |
| 353 sms-erase-range start-rec end-rec | |
| 354 | |
| 355 This command erases the specified range of records in EF_SMS. The starting | |
| 356 record must be identified by number (SIM record numbers are 1-based); the | |
| 357 ending record argument may be either as a number or the "end" keyword. | |
