Hi Steven:
I am very interested in this thread (about connecting a DOS and a BL box)

My nullmodem cable is a parallel one, so that I want to connect it to the
LPT1.
Up to now, I have solved my problem of connecting boxes under DOS. But I
would like to know how to do it under BL.

I supose these programs are freely available.

And that is all? So easy?

I do not need anything else.

With this method we do not need to install anything else to the BL, right?

So if does not use telnet, what kind of server does it use to do the

So we must install minicom.tgz package, right?

Could it work direct-connecting it to a parallel port?

Thank you.
