Drucker SPOOLER

Es folgt die Originaldokumentation der englischen Firma M.M.L. Systems Ltd. für die Spooler-RSX:


    ==========================================================
    SPOOL - CP/M Plus LST: SPOOLER for computers with M: drive
    ==========================================================

SPOOL  is  a utility which automatically spools all output to  the 
LST:  device (Printer) using the fast silicon ram memory disk  M:. 
Using  the  spooler,  the  computer is  available  for  additional 
processing  whilst  the printing continues in the  background.  In 
addition, many types of printing are actually produced faster with 
the  SPOOL utility as the computer no longer has to wait  for  the 
printer to be ready during processing.

The SPOOL utility is very easy to activate,  simply type SPOOL and 
spooling  automatically  starts.  This can be done as part of  the 
initial procedures when the computer is first switched on.

The  utility DESPOOL removes the SPOOL utility when,  for  example 
the  printer is jamed,  and it is necessary to start the  printing 
again.

|              CP/M 2.2 nor MP/M II.                             |

| SPOOL: *** Cannot load SPOOL - Insufficient common memory      |
|              The SPOOL utility requires to be loaded into      |
|              'common' memory. The most likely cause of this    |
|              error is the presence of other RSXs consuming     |
|              the common memory space available.                |
|                                                                |
| SPOOL: ERROR - No M: RAM DISK MEMORY found                     |
|              The SPOOL utility requires the logical drive      |
|              name M: to be assigned to silicon ram memory.     |
|              SPOOL was unable to select this disc drive or     |
|              the M: drive failed to be validated as a          |
|              silicon ram memory drive.                         |

| SPOOL: Spooler file already exists - Delete it first (Y/N) ?   |
|              The SPOOL utility uses a file of name             |
|              M:spooler.$$$ and this file already exists        |
|              perhaps because the SPOOL utility has been        |
|              previously used.                                  |

|              The SPOOL utility could not delete the file       |
|              M:spooler.$$$ either because it is a read only    |
|              file or because the M: drive was read only,       |

The  SPOOL  utility is an RSX which is loaded at the  top  of  the 
Transient  Program  Area  (TPA)  and the remove flag  is  not  set 
forcing  the RSX to remain in place.  The RSX requires 8 pages  of 
memory which includes a one page buffer area. The SPOOL RSX spools 
LST: output onto the file M:spooler.$$$ and removes data from this 
file  whenever  a  console input request is made  and  no  console 
character is ready and when the LST:  physical device (or devices) 
are ready.
