Parallel port Interfacing
Posted on 2001-08-19
how can i send data tru parallel port
or ACCEPT DATA Coming from outside.
all i know at port 378h you can assign a
value tru it example when you let
378h:=1 then on the parallel Port PIN 2
The (5 Volts) is On or HIGH when you
put a 0 on port 378h then all PINS from 2 to
9 will have no volts and it will remain as low.
how can i do that in Delphi
and also how can i accept data ?
on PIN 10,11,12,13 ON the parallel port
have a HIGH signal having 5Volts on each pin.
when i SUPPPLY a LOW signal in each pin a data
received on port 379H. exp.
exp. on Turbo Pascal
--when you send a LOW Signal on pin 10 THE VALUE
of Port[$379] is 63.
How can i do this in DELPHI or is there another
way to received a data in Delphi?
