Hey! I talked to you before about this same problem. I believe you may have been the one that suspected the "AT&Q5" to be the problem with the "output stalled" messages. Have you tried switching to "&Q6" to see if that fixed the problem? As for the Xem board, the way I alleviated the problem was to use the old firmware for the Xem board. You can do this by editing your digisetup command in the /etc/rc file. This is what you would change it to: /usr/sbin/digisetup -l 48 -o /dev/ttyA00 The "48" is the number of ports you want initialized, you can leave it at 48 or change it to 32, it doesn't really matter as long as you have at least as many ports as you want to run. This command will cause the older firmware to be loaded rather than the newer firmware. This was BSDI's recommendation, and they seemed a bit disturbed that we had to do this. I have a feeling that they developed a new firmware driver for the digiboard in BSDI 2.1, and it hasn't been perfected yet. Anyway, I found that using the older firmware did help tremendously, however, I do still see "output stalled" messages occasionally, but nothing like before. I am now wondering if maybe the Xem board can't handle more than 32 ports at 57600. We're running 48 right now. Digi says it will handle 57600 up to 32, but they say the performance will decrease once you add more than 32 ports. I'm now looking at the Comtrol Rocketport which will handle 128 ports at 57600, however, I still want to find out what is causing "output stalled" messages. Try using the older firmware and see if that helps. I would also appreciate it if you keep me posted on your progress. Thanks! *David* P.S. - Try to continue posting to the newsgroup when replying to me so others can contribute and learn from this.
