To be pedantically IBM, "midrange" terminals use twinax (and implement a
superset of the 5250 functionality).  "Mainframe" terminals are
traditionally 3270 descendants and connect via BNC/RG-62 coax or twisted
pair with BNC baluns.

The line is pretty darn blurred, especially when you take async terminal
channel controllers into account.  Some IBM shops did indeed use VT or VT
clones for data entry.
