[comp.unix.xenix] Printer-Magic

fag@norad.UUCP (Florian Gutzwiller) (09/15/88)

I  got quite other strange problems with 'lp'.  When I boot my 386-SCO on
my  25MHZ CPU only COM1 and COM2 are detected.  Some days ago LPT's  were
detected  too,  but now ??  The crazy thing is:  When I run  Norton's  SI
under  VP/ix  it detects again LPT1 and LPT2 and VP/ix does  even  print.
NOW!   Why does SCO not print ?  Is my bus too fast ?  - No.  What else ?
HEEELP ...


Sometimes I'd rather do some Black Magic ...

  This usually means that you are simply polling the devices faster than
they can respond. The autoconfig does something like
	out	something
	in	something
which all happens too fast for some boards to respond.

  I had the problem that when booting with cache the system thought it
had arnet boards. I "fixed" it by rebuilding the kernel with only
standard serial support (thanks, whoever told me about it). If you can
easily replace your parallel port, even as a test, you may be able to
solve or better identify the problem.
