I was struck by an idea while writing the article I just posted on getting the
DAK $199 CDROM drive going to comp.os.os2.misc. It's a really grody hack, but
has the advantage of sidestepping completely the question of how to do
low-level hardware access to all these unsupported devices:
How about an OS/2 device driver that, instead of talking to the hardware
directly, communicates (presumably via one or more named pipes) to a program
running in a specific DOS session, which would receive the requests and
process them?
Is this even possible under OS/2? Just how badly am I violating the OS/2
architecture? I know performance would stink, but it'd at least get access to
these devices under OS/2 for those of us who can't/don't want to spend several
hundred dollars on a SCSI adapter and supported CDROM drive. Is it documented
anywhere just what CDFS.IFS expects of a device driver it's talking to?
