My understanding of English grammar is that a comma should not precede an 'and' statement when describing a list - If I am mistaken on this understanding, please feel free to enlighten me. Be that the case however, I would rewrite your function as follows:

sub serial
{
    join( ', ', @_[ 0..$#_-1 ] ) . 
        ( @_ > 1 ? ' and ' : '' ) .
        $_[-1]
}

perl -le 'print+unpack("N",pack("B32","00000000000000000000001001001011"))'
