Back in the late 90s, I had a couple of VT-100 terminals that I
attached to my Linux boxes. Depending on where I was sitting, either
X or text terminal. Considering how much time I spent on an
telnetable BBS during that time, the VT-100 or xterm were equally
effective.
I do sometimes still use a serial console, usually minicom, for
debugging things.
Serial multiplexors used to be common in datacenters. Connect to the
multiplexor over ssh or equivalent, and select which physical device
on the rack to connect to. Most enterprise hardware would output the
boot screens (including BIOS) to the serial port. These days, I think
most of them run sshd or equivalent in the BIOS?
