Granted this isn't the usual question, but I've drawn a blank as to the proper way that I'm supposed to access a device (parallel port or serial port) under UN*X. I get the feeling I am supposed to get a file descriptor and ioctl the rest. I would like to know how to do the raw as well as "standard" (for serial I/O) communications, if there is any difference. Also, is it generally bad to attempt assembly under FreeBSD, or is there some special way to go about it? I am running 3.0-RELEASE and have other machines on 2.2.5-RELEASE and 2.2.7-RELEASE. I doubt that will make much difference except for ELF. -- Kris Kirby UAH Mail <kirbyk@email.uah.edu> UAH CS <kkirby@cs.uah.edu> Home <kris@airnet.net> WWW <nomurphy@hotmail.com> ------------------------------------------- TGIFreeBSD...
