6 | * This driver can be added to the RTEMS file system with a call to |

---|
8 | * From then on, you can open, read and close files on a remote FTP server |
---|
9 | * using the following syntax: |
---|
10 | * To open a file "myfile.txt" in the directory "mydir" (relative to home |
---|
11 | * directory) on a server named "myserver" using the user id |
---|
12 | * "myuserid" and the password "my_very_secret_password" you must |
---|
13 | * specify the following path: |
---|
14 | * |
---|
15 | * /FTP/myuserid:my_very_secret_password/@myserver/mydirectory/myfile.txt |
---|
16 | * |
---|
17 | * If the server is the default server specified in BOOTP, it can be ommitted: |
---|
18 | * |
---|
19 | * /FTP/myuserid:my_very_secret_password/mydirectory/myfile.txt |
