Well, I use an awfull hack here to communicate with small LCD displays via the parallel port, this seems like the opportunity to get some support for that too.. > ftp://smith.net.au/ppa/ppbus-970730.tgz I'll take a look.. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Søren Schmidt (sos@FreeBSD.org) FreeBSD Core Team Even more code to hack -- will it ever end ..
