Since you seem to be just taking data and pushing it off to disk, you might want to consider Sys::Syslog and use a syslog or syslog-ng daemon.

    A related program is www.cronolog.org . You might be able to use a command line like this one instead of writing any code:
    cat /dev/ttyS0 | cronolog /logs/serial_data_%Y-%m-%d

    [download]
    The above line will automatically create one log file per day and date-stamp it with the format YYYY-MM-DD .
