Again, I have no clue how these programs work. I'm using a VT100 Terminal.
This cable however is a DB9 female (MVME side) to DB25 male (VT100 side)
cable. So I cannot use it for the PeeCee.
I now have a cable with 2x DB9 female with

2 - 3
3 - 2
5 - 5
7 - 7

I have no idea how minicom or kermit works. I could set them up to use
9600 8N1 no_handshake.
I suppose I just start minicom (which somhow expects a modem, and (I
think) sends a character sequence to init. the modem of course does not
exist: there is just the above cable.
The transition module is a 712A/AM + 712B
If I start the MVME (or reset it) I don't get any output.

Help.
