Re: [uml-user] Problems reconnecting to serial line

Apologies for following-up to myself, but I'm still struggling with this
one.

How hard would it be to make it so that it never hangs up the TTY inside
the UML machine?  From my point of view, it would be perfectly
acceptable, possibly even desirable, that a session inside the machine
remains open through multiple connections to the pts. 

I've had a bit of a meddle myself, but my amateur attempts at hacking
this in have been somewhat unsuccessful.  I'm happy to continue trying,
but I'd be very grateful for some pointers.

thanks,

Paul
