I've only had need for this once, but when I 'realized' that a 
byte was just eight bits, my problem was solved. For you that 
depends on if you're ok with writing bits in multiples of eight, 
and that you can create the proper 8 bit seqeunces for your 
needs.  chr(0) through chr(255) should cover your needs, I think.

chr(107) + chr(168) will give you

'011010110101000'

CAVEAT: I might be completely off my rocker on this. 8-)

Good luck.
