There are plenty of things that can go wrong. Pins can go bad on M100 or pc side interfaces. The cable wiring can be flaky. The wiring of the cable can be substandard or non standard. If you build your own cable, if signal ground is not well connected it causes bizarre problems. Hey, is it possible you have more than one process competing for the port? Sometimes people try to set up a serial Getty process for remote login. That would have to be disabled for dlplus to work. The original dl could be set up AS a login process but I didn’t know what it was for at the time I started modifying it and disabled or removed it. So now if you run dlplus or LaddieAlpha you need to make sure nothing else is using the port. Say, inittab — John. — John. — John.
