That's a damn good question. Obviously the either RTS->CTS or DTR->DSR transition affects the adapter somehow. You can test it by using a 3-pin cable and have modem signals looped locally on the connector. In fact, it's probably the configuration you want to use for real. I would not trust the hardware flow control across pl2303 anyway. It's a driver developed by reverse-engineering. Prolific was not forthcoming with the documentation. -- Pete ------------------------------------------------------------------------- Take Surveys. Earn Cash.
