   Hi,

Usually qemu takes the server part, i.e. for serial ports you usually do 
'-serial telnet::$port,server,nowait', then 'telnet $host $port' to 
connect to your virtual serial line.  When the connection drops, just 
re-run telnet.

In my usage of qemu I didn't came across a use case which needs qemu 
reconnecting yet.

cheers,
   Gerd
