file transfer between Unix(Linux) and digital piano

hi all

how would one go about transfering files between a
Linux box with Yamaha S80 digital piano connected via
"to-host" serial cable ?

The S80 has some files on the smartcard which I would
like to backup
under Linux. What's needed for this ? Can I somehow
use a "midi dump" mechanism, or is a special sysex
needed ?

Idealy, this would be a perl program, but at this
point I'll take anything that will work with linux

thanks
john
