Answer 1

Try using a "*" after the format directive to eat all the elements in the list:

s.write [0x03, 0x00, 0x00, 0x16,
         0x11, 0xE0, 0x00, 0x00, 0x00, 
         0x01, 0x00, 0xC1, 0x02, 0x02, 
         0x02, 0xC2, 0x02, 0x02, 0x02, 
         0xC0, 0x01, 0x0A ].pack('C*')

There are lots of neat tricks possible with string#format so it's worth studying the documentation.
