You need to add STDIN and STDOUT to your $sel IO::Socket object and treat it like any other. If anything is available for reading, add it to the write queue for the other. If anything's in the write queue and the file handle is available for writing, write it.

Without selecting first (like you're doing implicitely via $sel->can_read), a sysread call will block until data is available to be read.

You may be interested in setting $|=1 (or doing $filehandle->autoflush), to keep stdio buffering from slowing you up.
