The L: directory

The L drawer contains a number of programs called Handlers. As with many parts of computing there is no simple way of explaining handlers so I'm going to go for a very rudimentary explanation. Handlers are high-level filing systems that allow the Amiga to understand "alien" file systems such as PC and Mac disks, or various Amiga ports such as the Parallel and Serial. They provide a high-level system friendly way of allowing the user to directly access these ports through the Workbench GUI and the AmigaShell CLI. To be activated handler must be either referred to in the MountList or a mount file specifically for the device.

Aux-Handler
The Aux-Handler provides access to an unbuffered serial I/O device.

The DosDrivers mount file for AUX is:

Handler = L:Aux-Handler
Stacksize = 1000
Priority = 5

Queue-Handler (PIPE:)
The Queue-Handler forms the basis of interprocess communication whilst applications are running through a virtual device called PIPE:

Port-Handler
As the name suggests, the Port-Handler provides an OS-friendly way of accessing the serial (SER:), parallel (PAR:), and printer (PRT) devices.

CrossDOSFileSystem
The CrossDOSFileSystem is required to access PC filesystems using CrossDOS.

FileSystem_Trans
The FileSystem_Trans directory contains data files that are required for the text translation in CrossDOS.

  • Dansk.crossdos - Filters Danish text files
  • INTL.crossdos - Preserves international characters
  • MAC.crossdos - Converts Apple Macintosh ASCII files.
CDFileSystem
The Standard Commodore CDFileSystem that provides basic access to CD-ROM drives. It is quite old and bugged, and should be replaced with a more modern file system capable of handling different versions of the ISO9600 standard, such as Asimware CDFS.

As mentioned elsewhere, if you want to find out more about it read "SystemGuide" by Dan Elgaard.
