View File tty3270-on-serial-line-of-s390.patch of Package util-linux (Project Base:System)

Support the special terminal on first serial line on a S/390(x) which
is due legacy reasons a block terminal of type 3270 or higher.  Whereas
the second serial line on a S/390(x) is a real character terminal which
is compatible with VT220.
