[linrad] Re: Linrad 02.06a




Linrad uses the parallel port to control the WSE hardware.
For this reason one has to run Linrad as root, something that also makes it easier to use svgalib.

Thanks, I shoud have read the manual.



If you want to disable the parallel port reads and writes,
set VALGRIND TRUE in vernr.h


Ok.


I have now downloaded Sarge and it does not support my Delta44
so I have to use the SCSI card in RDWR mode. This made me
discover a bug in 06a (and a few earlier ones): Linrad closes
the device before it stopped both input and output which
causes segfaults. It has nothing to do with Sarge, I noticed
because Sarge made me try RDWR which I had not done for quite some time.........

Interesting. At least your 12 hours download worth the effort!
RDWR is the mode I use!


Ramiro, since your hardware does not need the parallel
port, you should make a users hwaredriver that does not
offend your preferred mode of operation. That is another way to disable parallel port access.

Linrad 02-07 will (hopefully) give an error message rather
than a segfault.....

Thank you very much Leif for the suggestions. I hope one day I can understand how Linrad works internally. Anyway, I am learning C reading your code under Vim editor and it is a very good learning experience. This editor is really efficient for jumping between function calls. ;-)
