Howdy. After a 4 day stint working with Digiboard PC/16Xe cards, I've come to the conclusion that with the driver provided with FreeBSD, they can't stream all the ports to 57600 at the same time (the ports just stop xmitting data, and ppp links and ftp transfers stall, then die). I've worked with the Boca ATIO66 cards, getting 12 ports per machine, but I'm looking for a better footprint - approaching 32-64 serial ports per pentium (or pentium pro) that can handle 57600+ on all channels at the same time. I'm assuming the problem with the Digiboard is due to the polled IO (certain channels just get "lost"), but I haven't verified this yet. All channels work fine independantly, and in small groups (<5 streaming at once). Anyhow, if anyone has any suggestions as to hardware that they've tried that will physically support this port density, please let me know. -Brian
