Though that's odd because it's not specific to the 90L server. I do have a couple of 90L (not +) servers but I no longer have a power supply to drive them Then again, I'm also away from home at the moment so I can't do much off-hand anyway I'm afraid. The next thing to do would be to strace the latd daemon (Warning, this generates a lot of output!) with timestamps (strace -tt -p <pid>) to see just at which point the keystroke is being delayed. > Thanks a lot, > John <jo...@fo...> > P.S.

I've fixed that, and the right place is here: http://sourceforge.net/mailarchive/forum.php?forum_name=linux-decnet-user Feel free to send the strace output to the list, but don't expect a fast response - they are hard work to search through, I'm frightfully busy (even when not away from home), and I haven't looked much at the latd code in a couple of years now ... sorry. LAT is pretty much a one-woman project unless you fancy digging into the code yourself! Chrissie |
