Controlling a 10-pin non-standard parallel port
I have a Linux RedHat 7.3 (2.4.17 gcc 2.95.3) embedded on a PC board.
On this board, there is a small 10-pin non-standard parallel port (He10) that I would like to control thanks to ioctl() calls (PPCLAIM,...).
This should be possible by installing ppdev module (that does not seem to be here right now).
I did not install Linux myself and I am currently trying to find out which "Parallel Port Support" options shall be set in order to control it.
1. Which are the right options to set in that case (non-standard 10-pin port)?
-Multi-IO cards (parallel and serial)
-Support Foreign Harware
-IEEE 1284 transfer modes
Or which modules are required ?
Then, what config files/directories should I check to be sure my 10-pin parallel port is accessible and manageable (in /dev, /proc...) ?
2. I think "ppdev" allows me to manage this non-standard port, am I right ?
Thanks for your help.
