It is the driver who does all the work. i know that this printer will never work with fbsd or even linux so i hoped i could setup a qemu with win98 and just passing lpt0 throu ... but unfort. this does not work :( what i need is a possibility to give qemu/vmware access to lpt0 without any checking done by fbsd thx, regards, stan ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Well, I'm pretty sure you can. AFAIK the only difference is that lpt0.ctl ignores BUSY on open so lptcontrol can use it. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C pgpHOteqYASe8.pgp Description: PGP signature

It seriously looks like the printer, cable or port are broken, or the printer is very very special.. What sort of printer is it? You could try printing to /dev/lpt0.ctl since that will ignore BUSY for the open. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C pgpbzbQ9ql2e8.pgp Description: PGP signature
