Yeah, no kidding.

Put about 3/4 of the accounting packages in the WORLD in that basket.  They
deserve it.  Then shoot the programmers -- they deserve it too.

MCBA is an offender.  They try to talk direct to serial printers.  It
doesn't work much of the time, since they aren't smart enough to do an
ioctl() once they open the port!

Guess what?  You end up with a few processes "holding open" the port, which
can cause other problems.  That REALLY sucks, folks.

What they should do is use the "class" features of the spooler if they're
worried about special forms, or use the "forms" features in the SVR3
spooler.  But no, they have to be "cute" and write direct.

If I had a dollar for everytime I saw this........

And they wonder why people don't take Unix seriously in the business
marketplace?  It has nothing to do with the operating system, and everything
to do with the monkeys who program the applications for it.
