I'm really curious why the QuickTake is designed to only start transmitting once the serial port signals it's not ready. Is that some kind of proprietary change to make it harder to reverse-engineer? Is it a quirk of the way RS-232 is designed as a client-server protocol rather than peer-to-peer?
- bmonkey325 274 days agoRs-232 is an electrical signalling mechanism. The pins are there to create a protocol but it’s not enforced or required. In this case they are flashing DTR high low just to act as a “wake-up”. DTR being down doesn’t have control of what signals pass on the other pins eg Rx/Tx/CTS/RTS
