This is what tty_hangup() does, but it was implemented in 2.6.9. It may be just a bug with the order of zeroing for pointers. There was a fair amount of code shifting since then around those "if (port->tty)". Can you give it a new try to a more recent kernel? -- Pete ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
