I am using a socat command to create a tty interface on my embedded linux device like:

socat pty,link=/dev/ttyS9 TCP:10.0.10.1:9999

The connection is a long distance connecstion over a dsl-line. This line is disconnected every night and my tty interface is down. Is it possible to create the tty interace with a mechanism to reconnect until the server side is online again?

Next question: is it possible to call the socat command from a java programm?

Thanks a lot! Karl-Heinz
