As I said, the problem is not related to stty settings. Anyone using the machine experiences it, whether they are on when it first starts, or login once the server is in this state. I'm not sure where the problem lies, but it would appear to be at the tty device driver level. I have not yet checked to see if different ttys are updated all at once, or in round-robin fashion. However, all experience the one-second delay between updates. A stuck select() somewhere, perhaps? -- Brian Tao (BT300, taob@io.org, taob@ican.net) Systems and Network Administrator, Internet Canada Corp. "Though this be madness, yet there is method in't"
