AFAIK we're still using them at work. I've also used the Digiboard Xem adapters quite successfully on both FreeBSD and Solaris. Unfortunately, they are a bit tempramental on FreeBSD: They can't share interrupts (you get interrupt storms if you attempt it), digi(4) is limited to 16 ports (no expansion boxes) and digi(4) hasn't been adapted to the new TTY subsystem and so won't work on FreeBSD 8. >There's two ports which can make interfacing/using these devices, or a >multiport serial card, much easier -- Conserver[3]. I work with the guy >who wrote it, so I'm biased. :-) I can also thoroughly recommend conserver-com - as well as handling local serial devices, it can talk to serial-over-TCP ports, handles logging, distributed master/client hosts and allowed multiple people to connect to a single serial port (though only one person has write access at a time). Note that it's embedded in the LOM processor on (eg) Sun v20Z. --=20 Peter Jeremy --Dxnq1zWXvFF0Q93v Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (FreeBSD) iEYEARECAAYFAktNeyAACgkQ/opHv/APuIcDiQCeNrb1t5clWhnjiCdrCBQBhNX7 /38An2rP4SUNuff6L83aO0xauyZYA0To =2ujx -----END PGP SIGNATURE----- --Dxnq1zWXvFF0Q93v--
