13270 devices 2============ 3 4QEMU supports connecting an external 3270 terminal emulator (such as 5``x3270``) to make a single 3270 device available to a guest. Note that this 6supports basic features only. 7 8To provide a 3270 device to a guest, create a ``x-terminal3270`` linked to 9a ``tn3270`` chardev. The guest will see a 3270 channel device. In order 10to actually be able to use it, attach the ``x3270`` emulator to the chardev. 11 12Example configuration 13--------------------- 14 15* Add a ``tn3270`` chardev and a ``x-terminal3270`` to the QEMU command line:: 16 17 -chardev socket,id=char_0,host=0.0.0.0,port=2300,nowait,server,tn3270 18 -device x-terminal3270,chardev=char_0,devno=fe.0.000a,id=terminal_0 19 20* Start the guest. In the guest, use ``chccwdev -e 0.0.000a`` to enable 21 the device. 22 23* On the host, start the ``x3270`` emulator:: 24 25 x3270 <host>:2300 26 27* In the guest, locate the 3270 device node under ``/dev/3270/`` (say, 28 ``tty1``) and start a getty on it:: 29 30 systemctl start serial-getty@3270-tty1.service 31 32This should get you an addtional tty for logging into the guest. 33
