The ppi(4) man page has a code fragment to get y= ou=20 started. The program you have in mind would be quite easy to write.. Read config, Op= en=20 PPI, Daemonize, poll the parallel port. The only problem is that the parallel port can't capture edges so you would= =20 need to poll fairly frequently if you are trying to capture a button press. =2D-=20 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 --nextPart1423603.AkcVOqVo0C Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (FreeBSD) iD8DBQBEAEp95ZPcIHs/zowRAr/hAKCCQS+tJhx2yUiYaYDAzui93oJqywCgrIG7 Fdvp0nkFvsNfkeGufIh8kkc= =I5An -----END PGP SIGNATURE----- --nextPart1423603.AkcVOqVo0C--
