Practically any DTE-DTE cabling ought to work fine. A lot of folks around here suggest sticking with a USB/RS-232 bridge with an FTDI chip but I've never gone out of my way to get one. I use one of the basic StarTech ones with null wiring built in. Then it's DB9 to DB25 and I'm good to go. Something to keep in mind on macOS in particular is that the /dev/cu.* device is dynamically created and doesn't consistently come up with the same name. More than once I've had to fish around in /dev to find what it decided to call the serial bridge today. Once that's squared away I can bring up a getty or fire up dl2/LaddieAlpha with no problem. John's note about DSR/DTR is worth paying attention to. I've never had to concern myself with it using either of my RS-232 bridges but not all cabling setups take care of this for you. It looks like StarTech does business in NL so you might have good luck picking up something from them. They're not cheap but StarTech makes great stuff as a whole. I think it's the ICUSB232PROC. It's a Prolific chip rather than FTDI but those have never given me a problem; my guess is that the folks who struggle with them are Windows users and that the drivers are bunk there.
