PS1CardLink - help with cable needed

[Shendo]

Do you have a multimeter? Check continuity from adapter to the end of the serial cable.
Also make sure that you actually connect to TX and RX lines on a cable.

And leave CTS - DTR connected at all times.

BTW: BIOS and games won't print debug info even if your cable is working properly because serial port is disabled.

No$psx emulator prints that info regardless of the port status
(or in fact only when it's disabled, completely opposite).

On a real PS1 software like my PS1CardLink needs to activate serial port for communication.
Best option for debugging is burning a PSY-Q echo sample.

Your link cable it too long, shorten the cable will reduce the errors in data transmission.
