If I the software will stop when trying to read from the child...? I
also thought this was strange and that you should be able to read/write
to the child in sequences...

That is true that the line should end with a \n to be processed by the
awk script that looks like :

#!/bin/awk -f
/\.[mM][pP]3/ {print $0}

But changing the software to send \n to the child I still have to close
the run->pc[OUTPUT] to be able to read anything at all... If I try to
read without doing that the software hangs...
