I noticed a few days ago that the user telnet program acted "weird" when
it was run from the console; terminals on the dh worked just fine. Upon
closer examination of the kl driver, I noticed that logic to support the
select() system call was missing. It's a simple 5 line fix to the device
driver. A diff -c follows (kl.c~ is the older one).
