I started "/empeg/bin/player -s- 2>&1 >/dev/null &", but I still couldn't get back to my shell.
All the keys listed http://www.empeg.mars.org/devel/software/player.php3 worked.
What's wrong?

UPDATE:
Besides player prints that usage message:

player [options]

Options:
-u Enable USB server.
-i Ignore emergency persist data.

When I run "/empeg/bin/player -s &" I have to type each key two times for the shell to get it.

Running "ltrace /empeg/bin/player -s" showed that player still touches /dev/ttyS1:
memcpy(0x02127400, "/dev/ttyS1", 10) = 0x02127400

How can I trust the information posted here by the empeg guys?
