Re: serial device

[Tim Hurman <kano-tlug@example.com>]

Can ou post a little more info please. Is this something you wrote?, if
so, what arguments are you using to open the device. If not, are you sure
no locks exist in /var/lock/ or elsewhere . The reason I ask is this, when
a program crashed, the Linux should clean up after it, un-allocating it's
memory, closing it's file descriptors, sockets etc so the serial port
should be ok to open again.

If you did write it, what is the value of errno when open fails, if you
didn't, run the program with strace and see what it is up to.
