The command SFDATE sets the installation date of a file. The file have not 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!
That command SFDATE has always the same format. It is as a consequence built into the PLP:
| Header | PLP | RFSV SFSTAT | Footer | CRC | |||
|---|---|---|---|---|---|---|---|
| 16 10 02 | 32 03 02 01 | Command 28 00 |
Size 17 00 |
Creation date 12 34 56 78 |
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 SFDATE consists of 4 information units. These have the following meanings:
| Length in byte | possible values | Meaning | |
|---|---|---|---|
| Command | 2 byte | 00 28 (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! |
| Creation date | 4 byte | variable | This value determines the creation date of the file. The specification effected in seconds since that 1,1,1970 and contains thus also the creation time. |
| 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 SFDATE 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:
