Are you *really* shure?

The confusion is continuing...

As far as I know, there are two signals on the parport: the SELECT (Pin
13) and SELECT_IN (Pin 17). The IN in SELECT_IN is seen from the
printer's point of view (it's a input for the printer, and an output on
the PC side). You cannot control the SELECT line (as it's an input line,
and the corresponding bit is in the status register), but you can
control the SELECT_IN signal (by setting the bit in the control register).

I have no clue why this should work for you, Stefan.


bye, Michael
