RFSV command PATHTEST


Description of command

The command PATHTEST used over to test whether a path is correct and can be used. Whereby me however the difference to the command PARSE is not quite clear.

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!


Transmission direction (command) in the interface format

The instruction is PATHTEST as a consequence built into the PLP:

Header PLP RFSV PATHTEST Footer CRC
16 10 02 32 03 02 01 Command
22 00
Size
11 00
File name
"REM::\M:\AGN\AGENDA.AGN"
10 03 12 34

Receipt direction (result) in the interface format

A valid response takes place with the command RESPONSE and returns the delivery an error code. If 00 00 is supplied, then the path is correct and can be used. A predicate about whether the path existed or not, not returned the delivery of this command.

boldValues represent fixed of values, which are used accurately in such a way!
italicValues represent examples, which have a different meaning on the basis the instruction.

Description of command

The command FOPEN consists of 3 information units. These have the following meanings:

Length in byte possible values Meaning
Command 2 byte 00 22 (fixed) The command identifier has always the same value!
Size 2 byte variable Since the path name with is transmitted, the value of the length of the path name, needed here, depends! The final 0-Bytes is to be considered with the length
Path name 1 byte or more 0-terminated string The path name is to be transmitted, which is to be checked.

Description of result

The command PATHTEST is answered with RESPONSE. This returns the delivery an error code as result.

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:
NO_ERROR 00 00No error occurred
You can look at all defined errorvalues.
