I have spend some time on it last night and found nothing.

However, the I just realized how simple this one is ;-)
The "futurlec" uses STROBE as MOSI and we only save and restore 
PPIDATA, not PPICTRL ;-(

I will do a patch right away. This patch will also remove the save() 
and restore() functions.

However, according to the documentation of the old TL16C452 the 
STROBE-pin is an I/O-pin. Technically it is an open-drain output. So 
if STROBE is high (from the PC-point-of-view), we don't read high, 
but the value on the pin, AFAIK.
