/*******************************************************************************
Skeleton driver for Siemens Bitel and similar BtX terminals.
"Bitel" apparently stands for "Bildschirmtext + Telefon."
"Fe Ap" is short for "Fernsprechapparat."
Both of these terminals have an integrated membrane keyboard and a
telephone receiver mounted on top of the black-and-white monitor.
