Failed Serial ports

[richard]

My serial port has stopped working on my A500+

I was able to share files between my Amiga and PC without any problems, then all of a sudden they couldnt talk to each other.

Using Coloanto's AmigaExplorer, all that gets sent to the PC is garbage.

Do you think that my PSU could be failing? How can I test it?

I have checked the serial cable over and over again. Also tried different serial ports on my PC and another PC.

It has to be on my Amiga side. Other packages also dont work. (TwinExpress)
