This is - unfortunately - true for every serial console (nothing specific to s390), as there's no architected interface to transport console size changes. By running /usr/bin/resize, the actual cols/rows will be set.

  s390x qemu vt220 terminal, tput cols and lines is wrong

Bug description:
  s390x qemu vt220 terminal, tput cols and lines is reported as 80x24,
  whilst that's not true.

  The number of columns is semi-true, as the shell wraps them, however,
  one can print things beyond 80 cols.

  Ideally resizing qemu window, should manage to report the actual
  number of lines and columns to the underlying terminal.

  Similarly, one should be able to resize ASCII terminal window in HMC
  beyond 80x24.

  These days everyone has HD widescreen monitors, there is no reason to
  limit to 80x24.
