I'm looking for the source code for the PL2303 USB to RS232 adapter cable. I hope to make it somewhat more functional.
I have had good luck with the device. The driver seems to sense hardware signal changes (DCE ready, DCD, CTS). At 110 baud, the meter needle swings when connected to the Tx pin, and I type a character at the keyboard. But there is no echo when I connect Rx to Tx. (This is under Win XP SP3).
The driver version that works is V2.0.0.26, dated 25/06/2004, and has the name "USB to Serial Comm Port" an earlier version (V2.0.0.25) named "USB to Serial Port Bridge" also seems to work. Later drivers (2009, 2010) don't work with this cable. I did not purchase this cable directly from Prolific.
I have had similar results with these drivers under Vista Home Premium.
