With the ratios of on and off bits, though, wouldn't it be possible to use, say, 512 bytes per value? I don't understand how the start and end bits work, exactly. I happen to have a HIN232: http://www.hobbyengineering.com/H1345.html Although I'm guessing that it will be simpler without the extra volts.
Baud rate is something I don't understand too. Would a super-high baud rate minimalize the effects of the start/end bits? ANYWAY, I'm still not sure how to use the [comport] object. I tried the help patch, but I don't know how to test it. -Chuckk On 11/6/06, Martin Peach <[EMAIL PROTECTED]> wrote:

You can toggle the handshaking lines at high speed but you will run into the jitter caused by pd's audio block size. Or you could send data through the serial port with different ratios of on and off bits, but you will only get 8 different levels. I think you need to put a serial dac there. It's possible to clock serial data into a dac using just the handshaking lines -- one serves as a clock and the other data. Martin
