If you regularly have long-running sessions, and you might need to 
disconnect from and reconnect to them, you should start them from 
within screen (misc/screen).

If you have really important things in that session right now that you 
can only recover immediatly, you could try the snp(4) device together 
with watch(8) to hook onto the tty, but your success might be limited 
by the fact that the tty is effectivly closed. snp(4) can be loaded as 
a module.


Good luck,
Stefan
