How do I recover control of a serial port? cu reports tty0 not available, ps shows nothing running, but if I call init 1, wait a bit, call init 2, wait till the console responds and try again it usually works. If the line is busy and I reboot, the port seems usually to remain busy. Any ideas? bob prohaska

It sometimes gets left around by cu or getty. -- Andy Peterman | Opinions expressed treehouse!andyp@gvgpsa.gvg.tek.com | are definitely those of (916) 273-4569 | my employer!

It should remove stale locks automatically, but it does not. --- Alexis Rosen Owner/Sysadmin, PANIX Public Access Unix, NY {cmcl2,apple}!panix!alexis
