Somewhere I've got an old RS232 breakout box for testing/patching/setting all those signals.

Mind you in many cases a paper clip usually did the trick

You often find that some devices use x-on/x-off which makes life difficult and can be looking for DSR too. And devices like lasers of course often need a page throw of some sort to force a print out, otherwise it just gets buffered internally.

Xon Xoff only works with a Tx data and a Rx data connection between the kit.

The interface only has Tx data connected.... thats what threw me a bit at first.

All sussed now.. I even got the laser to work after a fashion...

a Life ?

really really sorry but the chance was there and I`m too weak LOL

Very good

Yes, that's why I said anything that uses Xon/Xoff would be difficult (impossible?)

Glad you got it working, I was getting ready to dig out all my old serial interface documentation. Just for amusement like
