Hello @misc,
I could not resist more againist the strength of OpenBSD and PF so switched
to this great OS from Linux at my network servers.
Also i have to admit that OpenSmtpd is my next target. For the first,
thanks to all who contributed these technologies.
Here is my problem.
I need to implement OpenBSD device driver for an unsupported parallel LCD
display module. The vendor supplied me some information and also linux
driver.
I read this paper :
http://www.openbsd.org/papers/opencon06-drivers/index.html
But i could not clearly understand how to develop device driver code under
OpenBSD.
I know that OpenBSD is againist to binary blobs so i do. So should i ignore
man lkm?
Please tell me a fresh start point. Is there any device driver template?
Any supported parallel port lcd display module's code to strip?
Are you talking about a NxM character LCD display connected to the
"printer port", and if so, are you using it as a proper display or do
you merely need to be able to feed it some characters now and then?
Rather, from the [partial lack of] information you supply, do you really
need a driver, or would accessing the device through /dev/lpt0 be enough?
