Is it possible with OpenBSD i386 to use the parallel port for lcdproc?
More specifically:
Did something change at OpenBSD i386 between 5.9 and 6.0
related to parallel port / lpt hardware permissions?
Up to OpenBSD i386 5.9,
I used to be able to have a working case-LCD-screen
with lcdproc-0.5.7, driver=hd44780, winamp wiring, with 'allowaperture'.
At OpenBSD i386 6.0 and after, it fails.
I have a computer case with a builtin LCD screen.
(Actually a VFD - vacuum fluorescent display)
Silverstone LC03V, has a Samsung 16T202DA1E, which uses the HD44780 protocol
with a cable from the 14 pins on the 16T202DA1E connected to a parallel
port DB25 in the 'winamp' pin wiring style.
The motherboard is an Intel D2700MUD with a parallel port on back panel.
Stripped to the essentials:
- install OpenBSD i386
- lcdproc-0.5.7.tar.gz from sourceforge
compile from source, because package does not include proper hd44780,
and I only needed the LCDd server and the hd44780.so driver
./configure --sysconfdir=/etc/ --enable-drivers=hd44780
cd shared; make
cd server; make
only need:
LCDd (to /usr/local/sbin )
hd44780.so (/usr/local/lib/lcdproc )
created a simple /etc/LCDd.conf, including importantly
Driver=hd44780, ConnectionType=winamp
For OpenBSD i386 (5.8 and 5.9), there seemed to be a permissions issue on the
0x378.
So the tweak that I had to use in the past was to 'allowaperture'
/etc/sysctl.conf
machdep.allowaperture=1
by OS release:
5.9/i386 fail: hd44780: cannot get IO-permission for 0x378: Operation not
permitted
5.9/i386 w/sysctl.conf machdep.allowaperture=1 : ***works***
(for the following these are with machdep.allowaperture=1)
6.0/i386 fail: hd44780: cannot get IO-permission for 0x378: No such file or
directory
6.1/i386 fail: hd44780: cannot get IO-permission for 0x378: No such file or
directory
6.3/i386 fail: hd44780: cannot get IO-permission for 0x378: No such file or
directory
6.7/i386 fail: hd44780: cannot get IO-permission for 0x378: No such file or
directory
I noted that previously (5.8 and 5.9), without allowaperture,
there was a warning "Operation not permitted" that was fixed with
'allowaperture'.
After 6.0, the warning says "No such file or directory"
Also I saw some web pages suggesting 'securelevel' may be a problem
for low level device interfacing, so I tried
6.0/i386 with /etc/rc.securelevel
/usr/local/sbin/LCDd -u root -r 5
This still fails.
Could tell me if they know about this parallel port issue and if there is a fix?
Thanks very much
