Three things:
>How are you running this DOS program under Linux? Have you re-compiled,
or are you using something like dosemu, qemu, or wine? As if it's the
latter, you may be able to set LPT1 in the configuration file.
I have been running it under dosbox. The accounting program (which I
have been using since 1987) is a pure DOS program.
Unfortunately, dosbox does not know anything about printer ports.
Wine does not do DOS programs...
I have been completely unable to get dosemu to install and run...the
'freedos' hd image install never works.
>Or you may just find that adding a networked printer and calling it
LPT2 works fine.
And where *exactly* would I call it 'LPT2' (or lpt2'. There seems to be
no correlation between the printer name and the port which it uses...Of
course there is a correlation by none of the config tools make that
visible and I am unable to find any config which sets that out. Both
OS/2 and Winblows make that correlation quite visible....I know it must
exist, the question is where is the damn thing!

print to the filename, and the data would be set to the waiting program.
I haven't tested this fully, but something like
rm /tmp/fifo # make sure there's nothing already there
mkfifo /tmp/fifo
lp -d printername </tmp/fifo & # & keeps the lp command running
~/dos/program.exe
should allow you to "print" a file to /tmp/fifo and have them come out
where you want.
This has possibilities. I will try it with a fifo called 'lpt2....
One other, fairly obvious thing: please remember to change the subject
line back if you're going to respond to a digest? Otherwise your message
gets "lost".
Yeah, noticed that myself....
