As I haven't found the time to translate the documentation into English
I shall give a short introduction here. German readers may move on to
SPULER45.DVI or SPULER45.TXT straight away.
FUNCTION
The heart of SPULER45 is an interrupt spooler. It writes data given to
the BIOS into a buffer and prints it out asynchronously in the
background. Since version 4.4 there is also a file spooler available
which utilizes the interrupt spooler to print out large files. The file
spooler is designed as a GEM-process that runs parallel to the main
application.
INSTALLATION
Simply put SP45_TSR.PRG into the AUTO folder. If you want to use the
file spooler or want to have some control over the spool process simply
start SPULER45.APP. However, on singletasking machines it may be a
good idea to rename it to SPULER45.ACC and to put it wherever your
accessories are, normally on C:\.
USAGE OF THE TSR
The TSR is completely invisible to you, apart from the fact that
printing seems to be more fluent now. You can, however, change the
configuration (i.e. the buffer size and two delays to play with in case
of lost characters) by starting SP45_CFG.PRG. The changes will come
into effect after the next boot.
USAGE OF THE ACC/APP
Starting with a filename as a parameter or dragging a file on the ACC
in GEMINI initiates the file spooler. Activating without filename can
have three possible consequences:
(1) Normally the main window will appear, showing the status as a bar
graph.
(2) If LSHIFT is pressed a dialog box will pop up and allow you to
cancel printing. In any case the spooler will be completely
reinitialized on exiting the dialog.
(3) If CONTROL is pressed you will be asked for a file to be spooled
out.
Clicking into the main window with LSHIFT or CONTROL has the
corresponding effect.
FEATURES
- small (TSR and ACC are without buffer <17 KB in memory)
- lean (no traps are being caught)
- quick (TSR in assembler, effective AES-binding)
- uses the AV-protocol
- version 3.0 was published in c't 6/90
- under MagiC or MultiTOS the file spooler is not halted by the screen
semaphore. Because of that a buffer of 8 KB is totally sufficient.
