The solution has to work for guests and natively in an LPAR.  Without
better 3270 support in Linux, a well-defined pipe that accepts ASCII is
the only reasonable solution, I think.  That means the integrated VT
console.  In an LPAR it talks to a VT emulator on the SE.  In VM, it
"simply" needs to be connected to a TCP pipe to a network-attached VT
emulator.
