Send data through Parallel Port

Hi Group,

I would be interested in getting information about data transmission through
a parallel port if anyone has had experience with it.  We have to send data
to LED displays and we sort of wonder what would be the easiest and most
reliable way (Com or Parallel?) to get it to work in Delphi 5.  Any
suggestions on components you would have seen would be appreciated and
samples or examples would be great :-).

Thank You
Andr

It depends on what OS you are running. for Win9x you can use asm to
access the port, OS>Win9x you need a component. Have a look at
groups.google, torry, ...

Re:Send data through Parallel Port


Hi all,

I would prefer the serial port.
I used in D5 a good (free) component to control the serial port:

Re:Send data through Parallel Port


I have actually found some components (a few) for transmitting data through
LPTs but what I am looking for is something with more control over the pins
of the DB-25 connector.  The test set we have to develop with requires a CLK
and CS pin and we need to be able to set them to Hi or Lo as necessary.  I
know this is far fetched but I also know it can be done, I simply lack the
experience and knowledge to get it done.
Any advice or previous experience would be appreciated.

Thank you again
Andr

I haven`t tried any of these components, but I think it should be
possible...
Again, what OS are you runnig?
If you are using asm on Win9x machines, you can set the pins as you like
it. (Have a search in groups.google, I posted these functions some time
ago, probably another delphi newsgroup but you should find it...)
