Maybe it's a silly question, but why is it needed to have a USB converter? Specifically, in the article, they mention connecting to a raspberry Pi. Couldn't they use the UART serial port on the GPIO of the Rpi? I see the baud rate seems limited to 4800, would that be the issue? (I don't know how this stuff work, I often use serial port to connect to my SBCs - RPi or similar - and I would love to use a minitel for that after reading the article ^^)
You don't if you are going into a serial port on the other side. I chose to go USB because it gives me flexibility to connect into a Raspberry Pi or my Mac or ...
Hi Alduin32,
May I ask you a related question?
I bought recently a VaxStation 3100 and tried to connect to it with a USB FTDI (I didn't try hard), but I was unable to get anything.
You basically just need an USB FTDI and a 3.3/5V TTL converter.
