Hello -- I'm trying to write out specific byte sequences over the
wire / to a file / etc.  Let's say for example that I wanted to write
out

99 111 108 108 105 110

as a simple, six byte sequence to a file.  In Java, I might use the
byte primitive, but it seems that in Ruby you have Fixnum and then a
Float for fractions.  If I simply create a Fixnum using the 99
literal, I think that that will create more than an 8-bit sequence
when I write out to the file.

Any ideas on how to do this?
