This maybe an issue with the SDrive-MAX hardware but I know RespeQt well and it can say I have never had that issue unless I have an actual SIO device collision. You see that with real hardware anyway. Anyway - just an opinion - not to trigger anyone. A little more info. https://github.com/pjones1063/RespeQt/blob/master/usb2pc_build_instructions.pdf I ordered both cables (PL2303 and FTDI) online. The PL2303 chipset one arrived first, so I made an SIO2PC cable with it, some old ATX power supply pins stuck into the SIO port on the back of my Atari 65XE. It worked fine with RespeQt handshake set to "None". It seems that speeds for this cable top out at 19200. Probably the limitations of not having any handshake? Still waiting for the FTDI version so I can build another cable with a CTS handshake. Quote Link to comment Share on other sites More sharing options...
