- That is a bug in the ROM 03 version of StatusTextDev. It caught me
- out in an earlier version of my ABOUT program, which was using
- StatusTextDev to see if the printer was online. Whenever trying to
- print on a ROM 03, it always brought up a dialog box saying the printer
- was offline! I fixed this in version 1.5, about a year ago.
-
- I seem to recall that this function doesn't work properly on a ROM 01
- either, but it has a DIFFERENT bug (I don't remember the details).
-
- In the end, I just used FWEntry to call the Pascal firmware's STATUS
- routine directly (by looking at the appropriate location in $C1xx to
- find the address, etc.)
