[Coco] VCC, NitrOS-9 and "/P"

[Stephen H. Fischer]

Hi,

The VCC emulator has support for the bitbanger printer port.

ChangeLog
Version 1.42 08/13/2010
Updated documentation.
Added Monitor Console for BitBanger Output.

The supplied NitrOS-9 "Preinstalled Hard disk image Nitros9 Ver 3.2.8" does 
not have the "/P" and "PRINTER" modules.

I am trying to keep my "OS-9 Multicolumn Printing software" project under 
control but I have run into trouble with several items including "/P".

The changes to my "C" program I think are simple but my twenty year old 
memory of "C" is failing me.

"EPS" is hardwired to output to "/P" and I wish to add a command line option 
to switch it's output to "stdout" so that it can write to a file using 
">filename.txt".

"OS9:ECHO This is a test >/P" produces a 221 error but my program gives no 
error.

"OS9:EPS BEll"

I want to test it's output to "/P" and have loaded the modules from my old 
boot disk but a 207 error occurred with "OS9:ECHO This is a test >/P".

How can I do this?

TIA.
