The command SFSTAT sets or resets various status information to a file. The file don't have to be opened!
It is to be noted that; all values, which are more greater than 8 bits in reverse order will transfer. The LOW byte sent as the first over the line and only then follows the HIGH byte!
The commands always the same format has SFSTAT. It is as a consequence built into the PLP:
| Header | PLP | RFSV SFSTAT | Footer | CRC | ||||
|---|---|---|---|---|---|---|---|---|
| 16 10 02 | 32 03 02 01 | Command 18 00 |
Size 17 00 |
Status info. 21 00 |
Filter 20 00 |
absolute file name "REM::/boot/home/psion/agenda.agn" |
10 03 | 12 34 |
A valid response takes place with the command RESPONSE and returns the delivery an error code.
| Header | PLP | RFSV RESPONSE | Footer | CRC | ||
|---|---|---|---|---|---|---|
| 16 10 02 | 33 02 03 01 | Command 2a 00 |
Size 02 00 |
Result 00 00 |
10 03 | 12 34 |
| bold | Values represent fixed of values, which are used accurately in such a way! |
| italic | Values represent examples, which have a different meaning on the basis the instruction. |
The command SFSTAT consists of 5 information units. These have the following meanings:
| Length in byte | possible values | Meaning | |||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Command | 2 byte | 00 18 (fixed) | The command identifier has always the same value! | ||||||||||||
| Size | 2 byte | variable | Since the file name with is transmitted, the value of the length of the file name, needed here, depends! The final 0-Bytes with the file name is to be likewise considered! | ||||||||||||
| Status info. | 2 byte | variable | The various Statics says outer whether the values will have to be deleted set, or. If the bit is set,
the appropriate value is to be set to delete otherwise.
|
||||||||||||
| Bit mask | 2 byte | variable | The bit mask determines, whether the appropriate bit in the field status info. is to be considered at all, or not. If the bit is here
set to zero, the value on the old status remains!
|
||||||||||||
| File name | 1 byte or more | 0-terminated string | The file name is to be transmitted, with which the values are to be modified. |
The command SFSTAT is answered with RESPONSE. This returns the delivery an error code as result. If 00 00 is returned the delivery, then no error occurred.
| Length in byte | possible values | Meaning | ||||
|---|---|---|---|---|---|---|
| Command | 2 byte | 00 2a (fixed) | The command identifier has always the same value! | |||
| Size | 2 byte | 00 02 (fixed) | Always 2 additional byte are supplied! | |||
| Result | 2 byte | variable | The result can obtain the following values:
