Under -current this would be trivial; see the ppi(4) manpage for geek-port access to the parallel port. The next set of updates to the ppbus code add a programmable port microsequencer to the driver, which would let you write a trivial in-kernel BDM driver that would be a lot faster. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
