Yep, there is a signal for that, "CONT". You can use the "kill" command 
to send it to your POV process (Despite its name, "kill" can send any 
signal to a process). You need the process id (PID) of the POV process 
to do that, which you can get from ps:

	ps -A | grep povray

The first number in the line shown is the PID. Use it with kill:

	kill -s CONT your_pid_here

You may need to grep for something else instead of "povray" if you're 
using MegaPOV.
