Novell's modem control is implemented in multiple environments. This section briefly describes how modem description files are used in each environment.
Modem description files on a NetWare server are placed in a subdirectory accessible to NetWare Loadable ModuleTM (NLMTM) files. The files for both the routing and the remote access components of Novell Internet Access Server 4.1 are located in the SYS:SYSTEM directory. You should work in this directory when adding new scripts, editing existing scripts, and compiling scripts. Novell Internet Access Server 4.1 uses all compiled scripts with the .MDC extension that exist in the SYS:SYSTEM directory.
The modem control components of the remote access software exist in a subdirectory called SYS:SYSTEM. All files containing compiled modem descriptions are copied to this subdirectory. When NetWare Asynchronous I/O (AIO) is loaded, it searches this subdirectory for files with the extension .MDC. AIO then creates a list of all modem names defined in these files and indicates which file contains the description for each modem. When one of the remote access services attempts a modem operation on a port, AIO determines which modem is attached to that port and ensures that the modem's description has been read into memory. AIO then starts the execution of the operation using the service's request parameters and the modem description.
The standard set of scripts that are included in the remote access software are contained in the following three files:
The routing software uses modem definition files that are placed in the SYS:SYSTEM directory. It interprets these files as required for modem control. The standard set of scripts that are included in the routing software are contained in the following three files:
