Greetings,
Well, as I learned from examining the driver, it intentionally
disables st devices based on certain criteria. I was not actually able
to discern the exact criteria used. Could someone please enlighten me a
bit here?
Also, as I mentioned before, I'm developing a printer driver for a
color plotter that emulates a SCSI tape. I've included the messages
which resulted from turning the debug on in st.c, and recreating the
problems that I have been having. The driver is being open sourced, and
the company who makes the plotter (Atlantek, Inc.) has been extremely
helpful in aiding my in the Linux development. Therefore, any
information whatsoever about what is going on would be greatly
appreciated.
