Perhaps there is an example somewhere of writing bits to a > serial port? Perhaps there is. Can you really send bits at a time? I don't think so. The PC serial port is byte oriented. You can send a byte with some bits masked off. The serial port uses start and stop bits to synchronize. I'd be curious to know what devices can receive bits less than an 8 bit byte.
