Surprisingly enough this is inside DOSBox documentation (Why was it hidden?)

I don't understand what you mean. Would you mind to rephrase using intelligible English?

directserial=false
comport=1

How connect in dosbox kontroller DS9097 for touch-memory?

Your serial port is already opened by another application

No luck yet with Dallas DS9097 (I try make it work too);
I will let you know when it is working.
Also try babelfish.altavista.com

Tried my serial port patch?

Thanks Hal; yes, I've also been using my own variant.
The problem is that the DS chipsets require REALLY accurate timing.
I was thinking of stubbing a little WinXX driver to assist, but I don't
think 6 months of work for a single application is going to be worth the effort.

No. Where it find?

Don't bother, that Dallas IButton/1-wire thing needs good timing...

(my patch is in the dosbox patches section)
